Product Details


Solid State Relays from Omron that are compact with a thin profile, ideal for close PCB mounting. They are a small bottom surface area SSR with a monoblock construction incorporating the PCB, terminals and a heatsink.

Bottom surface area approximately three times as small as that of the G3M, ideal for high density PCB applications
Mono-block lead frame incorporating terminals, heatsink and a PCB directly mounted with bare chips make it possible to miniaturise the relay
Isolation voltage 2.5kV
Dimensions (WxHxD) 4.5x20.5x24.5mm
Operating temperature range -30 to +80°C

Solid State Relay Interface Applications.

Controlling outputs from programmable controllers, positioning controllers plus other devices are transferred to actuators whilst providing isolation. The G3MC is suitable for applications that require frequent switching, noiseless operation and resistance to vibration, shock, dust and gas.

What does Zero Cross Function mean in SSR in Solid State Relays?

Zero cross function will allow the relay to turn ON when the AC load power supply approaches 0 V suppressing any noise generated with a sudden load current increase. Zero cross function is effective across 2 types of noise, noise on power lines and noise emitted into open space.

What is a Snubber Circuit in SSR – Solid State Relays?

A snubber circuit is a circuit which consists of a resistor and a capacitor preventing faulty ignition from happening within the SSR – solid state relay triac suppressing any sudden increases in the voltage applied.
