The high-current relay targets EV charging, renewable energy, and e-mobility applications, says Omron. Note that it expands the safety margin compared to the G9EK-1-E, which is rated for 200A/500VDC.
G9EK-1-EX
In terms of switching responses, the relay has a 50ms operating time and 30ms release time.
The company also highlights low contact resistance (15 mΩ), low coil power (4W), and enhanced shock and vibration resistance.
It measures 64.2 x 86 x 47.7mm (H x W x L) and the part has a mechanical longevity of 200,000 operations and the datasheet is on the Omron website.
Details on the part’s maximum switching capacity and carry current are shown below.
Vibration
Highlighting mechanical robustness, Omron writes:
“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.”
