1a 5A slim power relay for

interface

PA RELAYS

RoHS compliant

FEATURES

1. Slim size (width 5 mm .197 inch,
height 12.5 mm .492 inch) permits
higher density mounting

Despite the slim 5 mm width, the 20 mm
length is still compact and the 12.5 mm
profile is low. Even when a socket is
used, the height is still only 18 mm.
Suitable for high-density mounting, these
relays enable device size smaller.

2. Nominal operating power: High
sensitivity of 120mW

Enables smaller power supplies,
facilitates energy saving applications,
and contributes to device size smaller.

3. Control from low level loads to 5 A

Use of gold-clad twin contacts enables
control of low level loads do wn to 100 mV
100 µA and up to 5 A 250 V AC and 30 V
DC.

4. Reinforced according to IEC1131-2
(TÜV)

5. High surge breakdown voltage
(4000 V) and high breakdown voltage
(2000 V)

Between contacts and coil of 2,000 V and
surge resistance of 4,000 V work to
prevent controller malfunctions caused b y
noise and surges.

6. Outstanding vibration and shock
resistance.

Functional shock resistance: 147 m/s
Functional vibration resistance:
10 to 55 Hz (at double amplitude of

2.5 mm .098 inch)
Keeps equipment from miss-operation
due to vibration and shock.
Can be used as mounted on control
panel doors.

7. Sealed construction allows
automatic washing.

8. SIL (single in line) terminal layout

9. Complies with safety standards

Complies with Japanese Electrical
Appliance and Material Safety Law, and
certified by UL, CSA, and TÜV.

10. Sockets are available

TYPICAL APPLICATIONS

1. Industrial equipment, office
equipment

2. Measuring devices and test
equipment

3. Interface relays for programmable
controllers

4. Output relays in small de vices suc h
as timers, counters, sensors, and
temperature controllers.
