for a particular purpose. TE Connectivitys only obligations and liability
with respect to its products are governed solely by the TE Connecti-
vitys Standard Terms and Conditions of Sale for these products or the
respective written agreement under which the products are supplied.
TE CONNECTIVITY WILL IN NO CASE BE LIABLE IN ANY CIRCUM-
STANCES FOR ANY INCIDENTAL, INDIRECT, CONSEQUENTIAL
DAMAGES OR LOSS OF PROFITS ARISING FROM OR IN CONNEC-
TION WITH THE INFORMATION CONTAINED IN ITS DATASHEETS AND
CATALOGS OR IN CONNECTION WITH ITS PRODUCTS, INCLUDING,
BUT NOT LIMITED TO, THE SALE, RESALE, USE OR MISUSE OF ITS
PRODUCTS. USERS SHOULD RELY ON THEIR OWN JUDGMENT TO
EVALUATE THE SUITABILITY OF A PRODUCT FOR A CERTAIN PUR-
POSE AND TEST EACH PRODUCT FOR ITS INTENDED APPLICATION.
TE Connectivity strongly recommends to monitor the life cycle of the product
and to verify the relevant failure mode per IEC 61810-1 .
Technical data
Unless otherwise stated, the stated technical data are based on laboratory
tests under standardized conditions and are within the conditions of normal
use for these components . The vast number of influencing factors does not
allow TE to test its products for all imaginable applications and processes .
Furthermore, the large number of possible variations within a relay family
makes it impossible to give a comprehensive description of the different
characteristics for all variants in one datasheet . Typical data are derived from
the standard versions .
The decision on the suitability of a specific component is solely responsibility
of the user . To ensure the suitability of the product for a specific application
the user has to test these products before the use under the most stringent
conditions they will be exposed to in the actual application . Taking into
consideration the aspects of operational availability and safety, the user has
to rate the actual service life in an adequate relation to the expected life of
the relay .
The use of the relay beyond its specified characteristics or beyond suf-
ficiently tested life expectancy bears the risk of dangerous conditions; the
user has to prevent such conditions by adequate measures, being entirely
responsible in case of non-observance .
All product data are intended for users with knowledge and experience in
the application of such specifications . The utilization is at the entire risk of
the user .
The user has to verify the accordance with existing regulations and relevant
standards for the application; in particular with reference to the insulation
requirements as function of applied voltages and ambient conditions .
The standards (e .g . IEC 61810 'Electrical endurance') are based on the
principal assumption of occurences of malfunctions such as malfunction
to make contact, malfunction to break or as insufficient dielectric strength .
Such malfunctions have to be taken into consideration and must not ge-
nerate risks . Depending on the specific load, its characteristics and power
in the contact set, a relay malfunction situation may generate various risks
such as malfunction of the equipment and its controls, electrical shock, the
risk of excessive heat and fire and others . It is in the entire responsibility of
the user to provide for additional precautions against such possible effects
according to the relevant application standards .
Protection against risks under all operation conditions even in case of
malfunction can only be ensured by the design of the equipment as well
as by application instructions for the end user; it is the responsibility of the
manufacturer of the equipment to take the appropriate measures . Incorrect
connections by the user may lead to risks, faulty operation and abnormal
heating or fire . It is also the responsibility of the manufacturer of the equip-
ment to take appropriate measures to avoid potential danger of electrical
shock by preventing access to live parts of the relay including parts as
terminals and accessories .
Specification
In order to improve performance and quality, we continuously develop our
products . We reserve the right to change technical parameters and product
specifications . The technical data listed are for description purposes of the
components only and are not an agreement and do not guarantee specific
characteristics and parameters; for detailed questions, please contact our
application support . Drawings, photos data and descriptions are subject to
change without prior notice .
Availability
The databooks and datasheets list a broad range of products and the
descriptive part code structure (product code) does allow a large number
of possible variations, but not all possible variations are defined as standard
types in the current product portfolio (product code) and thus may not be
included in the product range . Some products are normally maintained in
stock for immediate delivery, or are available within 'normal leadtimes for
industry'; however, there may be extended leadtimes for some non-stock
items . Special versions to customer specifications may be supplied .
Additionally, minimum quantity requirements apply and these requirements
may differ from indicated packaging units . Please consult with your TE sales
organization or authorized distributor regarding availability and minimum
order requirements .

AC-coil
Relays for direct energization with AC supply . If not otherwise stated, the
data is given as V
rms
for 50 Hz supply .
Adjacent contacts
Insulation parameters between two adjacent contact circuits (poles of a
relay), which do not have a conductive connection . The level of insulation
depends on the relays design, rated voltage and ambient conditions .
Ambient temperature (function, in operation)
The temperature in the vicinity of the relay (distance according to IEC
61810-1) .The minimum ambient temperature is the miniumum operating
temperature, the maximum ambient temperature is the maximum opera-
ting temperature for the use of the relay or accessory when operated . This
temperature range should not be exceeded; within the indicated tempera-
ture range the ambient temperature does influence the electrical endurance .
Ambient temperature range according to IEC 61810-1 and indicated in °C .
Unless otherwise stated data is referred to an ambient temperature of 23°C .
Approvals
With the approval label the independent approval agency and/or test house
confirms the compliance with the relevant product standards and/or certain
product characteristics .
NOTE: the ordering code structure does allow a large number of possible
variations, but not all variations are defined as standard types (ordering
codes) and thus some relays may not be included in the list of approved
relays . It is recommended that users also seek the pertinent approval files
of the agencies/laboratories and review them to ensure that the selected
product is filed and meets the requirements . Technical data and approved
types on request .
Bandwidth
The range of frequencies for which the performance falls within the specified
limits .
Bifurcated contact
See > 'Twin contact' .
Bistable relay, latching relay
In a bistable or latching relay the contacts remain in the last switching positi-
on once the coil input voltage is disconnected .
Bistable relays only require a short set respectively reset pulse and do not
need any energization once the switching position changed . Unless otherwi-
se stated the bistable relays can endure a permanent energization .
NOTE: for some relay series a permanent coil power supply is not permit-
ted; in this case the maximum energization duration or the required coil
power reduction is indicated in the respective datasheet .
Bistable relay, switching characteristics
In a bistable relay, the contacts remain in the last switching position after the
input voltage is disconnected .
NOTE: Unlike monostable relays which return to their predefined contact
rest state in case of power supply break down and thus might be showing
a fail safe behaviour, bistable relays do not automatically return to such
predefined position . Therefore the application and relay control has to be
designed to cover such situations and bistable relays should not be used in
applications that are rated according to ISO/TS 16949 7 .5 .3 'Product Identi-
fication and Traceability' .
NOTE: Even though the bistable relays are leaving production preferrably
in reset contact position, the position of the contact (set position/reset
position) is not defined at delivery unless otherwise stated . The user needs
to check the contact position and to set/reset the relay to the required
position .
Bounce
An unintentional phenomenon that can occur during the making or breaking
of a contact circuit when the contact elements touch successively and
separate again before they have reached their final position .
Bounce time
The time from the first to the last closing or opening of a relay contact .
Unless otherwise stated the indicated times are maximum values and are for
energization with rated voltage, without any components in series or parallel
to the coil, and at reference temperature . Also see > 'Relay cycles' .
Breaking capacity max.
Product of the switching current and switching voltage (in W for direct cur-
rent, in VA for alternating current) . Also see > 'DC breaking capacity'
Bridging contact
Double contact configuration, where two movable contacts are mechani-
cally connected and operate simultaneously . In a bridge configuration, the
load current flows from one stationary contact via the bridge to a second
stationary contact . See also table 'Contact arrangement' .

Category of protection (IEC 61810)
The ´Relay Technology Categories´ (IEC 61810) describe the degree of
sealing of the relay case or its contact unit:
RT 0:
RT I:
RT II:
unenclosed relay
Relay not provided with a protective case .
dust protected relay
Relay provided with a case which protects its mechanism from
dust .
flux proof relay
Relay capable of being automatically soldered without allowing
the migration of solder fluxes beyond the intended areas . These
are the contacts, movable parts of the magnetic system and their
immediate environment .
wash tight (washable) relay
Relay capable of being automatically soldered and subsequently
undergoing a washing process to remove flux residues without
allowing the ingress of flux or washing solvents .
The test to evaluate the sealing of the case for wash tight relays is
performed according to the IEC 60068-2-17, Qc test .
NOTE - Please refer to the 'Processing' section for additional infor-
mation .
In service this type of relay is sometimes vented to the atmosphere
after soldering or washing process; in this case the requirements
with respect to clearances and creepage distances can change .
RT IV:
sealed relay
Relay provided with a case which has no venting to the outside
atmosphere, and having a time constant better than 2x10
4
s in
accordance with IEC 60068-2-17 .
hermetically sealed relay
Sealed relay having an enhanced level of sealing, assuring a time
constant better than 2x10
6
s in accordance with IEC 60068-2-17 .
Coil insulation system according to UL1446
These requirements cover test procedures to be used in the evaluation of
electrical insulation systems intended for connection to branch circuits rated
600V or less . This standard refers to insulation systems and does not cover
individual insulating materials .
Coil Operative range (graph)
Admissible range of energizing voltage with respect to the ambient tempera-
ture . The upper limit is the maximum coil voltage, the lower limit is the ope-
rate voltage U
min
(coil without pre-energization) and/or the operate voltage
U
1
(pre-energized coil) .
The diagrams are valid for single mounting of relays without thermal inter-
ference and connection wiring according to IEC 61810-1; unless otherwise
stated the data is indicated without contact load, thus not taking into
account the temperature rise due to the contact current .
The use of a relay with an energizeing voltage other than the rated coil volta-
ge may lead to reduced electrical life (mechanical and dynamic effects) .
In case the application requires an energization with other than the rated
coil voltage and a recommended voltage range is indicated, the coil voltage
should be within the recommended voltage range (shaded area) to keep the
effects on electrical life to a minimum .
curve 1: operate-/minimal voltage U

recommended voltage range (shaded area):
the coil voltage should be within the recommended voltage range
to keep adverse effects on electrical life to a minimum .

no other devices (e .g . diode) in parallel or in series to the coil
■
single mounting of relays .
Indicated data for the operative range class, is given for the minimum allo-
wed mounting distance .
Unless otherwise stated a duty factor of 100% (permanently operated) is
permissible .
Coil inductivity
The inductivity is a nonlinear parameter due to saturation effects and
depends, amongst others, on the position of the armature . The value of the
relay coil inductivity depends on the measurement method and its parame-
ters . Therefore the inductivity is not a generally guaranteed parameter; for
technical questions, please contact our technical support .
Coil operative range for bistable relays
curve 1: operate voltage at coil temperature equal to ambient temperature
curve 2: minimum reset voltage
curve 3: maximum operate voltage
curve 4: maximum reset voltage
For bistable relays, all curves are given for pulse energization (short energi-
zation duration) .

Coil power
Power consumption of the coil at rated coil voltage and coil resistance, with
coil temperature at 23°C, given as rated typical value .
Coil resistance
Electrical resistance of the relay coil at reference temperature; this value is
indicated for the coil without any other devices in parallel (e .g . coil suppres-
sion, diode, etc .) .
Coil suppression circuit
Circuit to reduce the inductive switch off voltage peak of the relay coil (EMC
protection, switch off voltage peak) . Most of such circuits reduce the
armature release speed, which may decrease the relay lifetime depending
on the application load . Especially diodes or any pn-junction of the electronic
control system in parallel to the coil will significantly reduce the electrical
lifetime . Recommended that relay performance testings to be evaluated with
the suppression that will be used .
Note: unless otherwise specified the indicated relay data refers to coils
without any components in parallel or in series to the coil .
Coil voltage
Voltage applied across the coil terminals .
Coil voltage range
Voltage range at which the relay displays the operating characteristics .
These specified operating characteristics are given for a constant DC supply
or sinusoidal AC supply . Other operating conditions (e .g . pulse control,
ramp voltage, half wave rectifying, etc .) may lead to characteristics other
than specified .
Coil-contact circuit data
Insulation parameters between the coil system and the contact circuit/sys-
tem .
Combination of relay and socket, insulation requirements
The relay standard IEC 61810-1 has an important impact on the combina-
tion of a relay and the respective socket . The relay sockets have to comply
with the requirements of IEC 61984 and the insulation reqirements of the
IEC 61810-1 . Even if the socket alone fullfills or exceeds the insulation
reqirements as clearance/creepage for the relay, the combination of a relay
with a socket may reduce the creepage and lead to a lower rated insula-
tion voltage . Hence restrictions for the combination relay-socket may be
the consequence, e .g . a reduction of the voltage range or of the pollution
degree . Especially for miniature multi-pole relay and respective sockets with
small distance between the contact circuits, these restrictions have a big
impact .
Apart from the insulation properties, the thermal characteristics of the
combination relay and socket are of utmost importance (see > 'Derating
curves') . As sockets from different sources are not directly comparable, the
compliance with the technical specification can only be confirmed for an
approved combination relay-socket . As design details and characteristics
for non TE products are beyond our control, confirmations for technical
parameters and characteristics regarding such combinations is not possible .
Risks as reduced dielectric strength, fire hazard, etc . due to use based on
unclear or omitted data, limitations or restrictions must not be underestima-
ted .
NOTE: We only confirm the characteristics and parameters for the approved
combinations of relays and sockets as indicated in the catalog and datas-
heets .

Contact material
The list gives an overview of the most important plating- and contact materi-
als and their use in signal-, automotive and general purpose relays .
The switching capacity of the contacts and the respective electrical endu-
rance depends not only on the contact material but also to a high degree on
the relay design . Decisive for the application therefore is the optimal combi-
nation of the mechanical system and the contact material . The characteris-
tics for certain relay types cannot be transferred to other designs, nor can
