● Please refer to “PCB Relays Common Precautions” for correct use.

●Mounting Position Compared to G2R Model

Although the G2RL model and the G2R model are both low profile Relays, their characteristics such as switching capacity are different. Be sure to check operation under the actual operating conditions before use.


The G2RL model is flux-resistant with two sealing holes on the case. Thus, do not clean the Relay by boiling or soaking in water. Consult your Omron sales representative for sealed type Relay.

●Using Relays in an Atmosphere Containing Corrosive Gas

Do not use Relays in an atmosphere containing corrosive gas (sulfuric or organic gas).Otherwise, connection failure due to corrosion on the contact surface may lead to functional faults.

●Coil Voltage Reduction (Holding Voltage) after Relay Operation

・If the coil voltage is reduced to the holding voltage after Relay operation, first apply the rated voltage to the coil for at least 100 ms, as shown below

・A voltage of at least 50% of the rated voltage is required for the coil holding voltage. Do not allow voltage fluctuations to cause the coil holding voltage to fall below this level.
