Correct Use

●Differences with the G2R

The G2RG-2A-X has the same terminal arrangement as the G2R-2A4 but the switching capacity and electrical endurance are different. Confirm that correct operation is possible in the actual operating conditions before using in applications.


The enclosure rating of this product is flux protection. Therefore, do not wash with water or detergent.


The contacts of this product have polarity. Be sufficiently careful because incorrect wiring may result in a failure to break the circuit.
This product is designed and manufactured under the assumption that it will be used with 2-pole series wiring.
Do not use it with 1 pole only.
Install the product in a dry location with little dust and corrosive gas.
Use in high temperature and humidity or an atmosphere containing corrosive gas may lead to the relay itself failing or suffering burn damage caused by performance deterioration due to the influence of condensation or corrosive materials.

●Connection of diodes to the operating coil

Connect a diode and zener diode to the relay coil (refer to the following figure).
The diodes are for coil surge absorption. Switching performance may be affected if only a diode is used, so use in combination with a zener diode.
The coil has no polarity. Connect the diodes in the reverse polarity of the voltage applied to the coil.
The recommended zener voltage of the zener diode is three times the rated coil voltage.



Do not use this product if it has been dropped.

●Electrical endurance

Since this product is specifically for high DC voltages, the final failure mode is failure to break the circuit, and in a worse-case scenario, burning may extend to surrounding components.
Do not exceed the specified ratings or number of operations during use, or use the product for any application other than high DC voltages.
Implement a safety circuit and other safety measures to minimize the risk in the event of a failure.
The electrical endurance of this product is the number of load switching operations with a resistive load under the standard testing conditions specified by OMRON.
The coil drive circuit, ambient environment, switching frequency, or load condition (use under an inductive load or capacitor load) may reduce the endurance and lead to a failure to break the circuit. Always confirm operation with the actual equipment.
