Miniature control relays
■
Description
The HH52, 53 and 54 are a series of
miniature general purpose relays
specially designed for users
demanding small size, sturdy
construction and high electrical
capacity. Mechanisms are furnished in
polycarbonate dust-proof enclosures
and are recommended for a multitude
of electrical control applications for
their reliability and compact size.
Continuous duty coils, either AC or DC
are available for voltages up to 240V
AC or 120V DC. Contacts can be
supplied in 2PDT, 3PDT, 4PDT
arrangements. Continuous current
ratings are 3, 5 and 7 Amps. Many
terminal types are available for solder,
plug-in or printed circuit board
mounting.
Features
• 3, 5 and 7 Amp. contacts
• 2PDT, 3PDT and 4PDT
• Reliable operation, long service life
• High dielectric strength
• Solder, PC board, wire wrap and
screw terminal socket
• AC or DC coils
• Barriered contacts for opposite
polarity available

General information
Contacts
Miniature relays can be supplied with
contacts that meet most electrical and
mechanical contact requirements. The
standard HH52, 53 and 54 series are of
the single contact type as illustrated.
The HH52W (2PDT) and HH54W (4PDT)
relays are supplied with bifurcated
contacts. These bifurcated contacts are
with good conducting characteristics
and are recommended where limited
control power is available.
The dielectric strength is 1000 volts rms
50/60Hz (between open contacts) which
makes them more than adequate for
power circuit use.
■
●
Special purpose relays can be supplied
with diode for surge suppression, for
operating display devices such as
LED's, and magnetically held type.
●
Enclosures
All miniature relays are enclosed in
sturdy heat-resistant polycarbonate
covers providing protection against
dust and dirt.

Operating status indicator
All relays can be supplied on request
with a visual indicating signal–a light
emitting diode (LED).
LED's are fitted to relays with nominal
operating voltages up to 240 volts.
The LED emits highly visible red light
for AC and green light for DC when
power is applied to the relay coil, an
extremely useful signal when trouble
shooting either equipment or a
system.
AF91-855
With operation indicator and surge
suppression device
This type has a built-in operation
indicator and suge suppressor.

Dual coil magnetically held
One coil firmly holds the contacts in
one position, the second coil releases
them.
This relay has a good memory stability
because it will maintain the ON
condition during loss of power. It
operates on a momentary pulse to
either coil. The relay saves space as
well as power, since a single unit
occupies half the space of a
mechanically interlocking latching relay
of the same rating.
Voltages: 6V–110V AC, 6V–48V DC

Surge suppression
We can also supply relays with a
diode (or CR) for surge suppression.
The highly efficient diode (or CR) is
connected in parallel with the coil in
order to suppress the surge
generated within the coil.
Consequently this coil can be used in
electric circuits which include highly
sensitive relays or transistors, etc.
without interfering with their
operation, so increasing the
dependability of the equipment.

With extra pick-up operating coil
This type is recommended for use in
poor power supply environments.
Pick-up voltage: 65% of rated voltage
(at 20°C)
Drop-out voltage: 10% of rated voltage
(at 20°C)
Mechanical durability: 10 million

Other specifications are the same as
those of the basic model.
High capacity type
This type is suitable for switching a
load like solenoid . The current rating
of the contacts is 7A for HH52PU and
5A for HH54PU. Other specifications
are the same as those of the basic
model.
