New G9EK-1-EX handles 250A, 500V, with efficiency, resilience, and gasless simplicity
Hoofddorp, The Netherlands, 4 February 2026 – OMRON Electronic Components Europe has introduced G9EK-1-EX DC power relays with 250A/500VDC switching rating for safety isolation in electric-vehicle charging infrastructure, renewable energy, and e-mobility applications.
Extending the G9EK screw-terminal series, the normally-open relays leverage an optimized internal structure that has contact resistance of only 15mΩ when closed and coil consumption of just 4W. By combining low power consumption and dissipation with greater switching current, in the 47.7mm x 86mm x 64.2mm high outline of other G9EK-1 relays, the G9EK-1-EX provides an efficient and space-saving alternative to high-current contactors. With its 250A/500VDC switching rating, the G9EK-1-EX expands the application reach and enhances safety margin compared to the G9EK-1-E, which is rated for 200A/500VDC.
The G9EK-1-EX contact mechanism provides enhanced tolerance to shock and vibration, withstanding shocks up to 100g for superior safety and reliability in e-mobility applications including industrial autonomous guided vehicles (AGVs). In addition, the G9EK-1-EX terminal structure minimizes magnetic repulsive forces generated by large currents during conditions such as short circuits, ensuring longer lifetime and greater reliability.
Targeting applications that demand outstanding electrical and mechanical robustness, Omron’s G9EK-1-EX relays handle interruption current up to 1000A at 400V and withstand voltage pulses up to 4000V. While the relays can handle superior current and voltage, their gasless design ensures safe operation and a simplified internal architecture with carbon-neutral credentials.
The G9EK-1-EX also ensures fast switching responses, with 50ms operating time and 30ms release time, as well as assured mechanical longevity of 200,000 operations.
