G5A
Subminiature 8.40 H x 9.90 W x 16 L mm
(0.33 H x 0.38 W x 0.63 L in)
Unique moving magnet armature (Moving
Loop System) reduces relay size, magnetic
interference, and contact bounce time
Low nominal power consumption (200 mW)
Bifurcated crossbar contact assures highly
reliable switching of loads as low as
10 mVDC, 0.1 mA (reference value)
Automatic flow or dip soldering possible
Available in standard, high-sensitivity,
high-dielectric (FCC part 68), low
thermoelectromotive force, and ultrasonic
cleaning versions
■ Highly stable magnetic circuit for latching
endurance and excellent resistance to
vibration and shock
■ Single or double coil winding types available

Hints on Correct Use
Single-winding type (G5AU)
Example of low-power drive circuit
1. The figure below shows a drive circuit (JAPAN PAT. NO.
1239293) in which the latching relay can function like a
general-purpose relay from a normal input pulse for
switching.
2. Use a charging current of capacitor C to operate the
latching relay, which flows suddenly through diode D1,
capacitor C, latching relay, and diode D2, and the relay
contacts will be put in the locked state.
3. Use a discharging current of capacitor C to release the
latching relay, which flows through transistor TR, capacitor
C, and the latching relay.

Notes:
1. When applying the relay for practical use, make sure of the
set or reset state of the relay; then determine the circuit
constraints.
2. Because OMRON possesses the patent of this drive
circuit, contact OMRON when adopting it.
