1 Form A 5A
slim power relay
for interface
RoHS compliant
Protective construction: Sealed type
FEATURES
1. Slim size (width 5 mm .197 inch,
height 12.5 mm .492 inch) permits
higher density mounting
Despite the slim 5 mm .197 inch width,
the 20 mm .787 inch 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 .709 inch. 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 down 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 by
noise and surges.
6. Outstanding vibration and shock
resistance
Functional shock resistance: 147 m/s2
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.
PA RELAYS
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 devices such
as timers, counters, sensors, and
temperature controllers
