Omron Electronics G9EK-1 High-Power DC Relays

Omron Electronics G9EK-1 High-Power DC Relays are UL-certified single-pole, single-throw (SPST) high-power relays that provide a cost-effective solution for DC disconnect applications. These Omron high-power relays switch at 120A at 500VDC bi-directionally, eliminating the need for multiple switching components to alternate forward and reverse currents. The G9EK-1 offers high shock and vibration characteristics coupled with the cost-effective benefits of hermetically sealed switching predecessors.
