TX-D

TESTING

High Breakdown

Voltage Relay

TX-D RELAYS

Destructive vibration resistance:

10 to 55 Hz (at double amplitude of

5 mm

.197 inch)

7. Sealed construction allows

automatic washing.

FEATURES

1. Approved to the supplementary

insulation class in the EN standards

(EN60950).

The insulation distance between the

contact and coil meet the

supplementary insulation class of the

EN60950 standards as required for

equipment connected to the telephone

lines in Europe.

Satisfies the following conditions:

• Clearances: 2.0 mm

.079 inch

• Creepage distance: 2.5 mm

.098 inch

or more

2. 3,000 V breakdown voltage between

contact and coil. (Surge breakdown

voltage 6,000 V type)

The body block construction of the coil

that is sealed formation offers a high

breakdown voltage of 3,000 V between

contact and coil.

3. Nominal operating power:

High sensitivity of 200 mW

By using the highly efficient polar

magnetic circuit “seesaw balance

mechanism”, a nominal operating

power of 200 mW has been achieved.

4. High contact capacity: 2 A 30 V DC

5. High contact reliability achieved

with gold-clad crossbar twin

contacts and the use of gas

expelling materials during

formation.

*We also offer TX-series relays with

AgPd contacts, suitable for use in low

level load analog circuits.

6. Outstanding vibration and shock

resistance.

Functional shock resistance: 750 m/s

Destructive shock resistance:

1,000 m/s

Functional vibration resistance:

10 to 55 Hz (at double amplitude of

3.3 mm

.130 inch)

TYPICAL APPLICATIONS

1. Facsimile

2. Modem

3. Communications (xDSL)

4. Medical equipment

5. Security

This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the actual

load. (AgPd contact type is available for low level load switching.)

The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. Refer to “6. Usage, Storage and Transport
