Hints on Correct Use
Single-winding type (G5AU)
Example of low-power drive circuit
1. The figure below shows a drive circuit (JAPA N PAT. N O. 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, latch-
ing 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.
Note: 1. When applying the relay for practical use, make sure of the
set or reset state of the relay; then determine the circuit con-
straints.
2. Because OMRO N possesses the patent of this drive circuit,
contact OMRO N when adopting it.
Precautions
Long-term Continuously ON Contacts
Using the Relay in a circuit where the Relay will be O N continuously
for long periods (without switching) can lead to unstable contacts
because the heat generated by the coil itself will affect the insulation,
causing a film to develop on the contact surfaces. We recommend
using a latching relay (magnetic-holding relay) in this kind of circuit. If
a single-side stable model must be used in this kind of circuit, we rec-
ommend using a fail-safe circuit design that provides protection
against contact failure or coil burnout.
Relay Handling
When washing the product after soldering the Relay to a PCB, use a
water-based solvent or alcohol-based solvent, and keep the solvent
temperature to less than 40 ° C. Do not put the Relay in a cold clean-
ing bath immediately after soldering.
