Contact resistance reduced to 1/10

*1. G7L-X: Initial 100 mΩ or less to G7L-X-SI: Initial 10 mΩ or less

Newly released low contact resistance type with initial 10 mΩ or less for the 1000 VDC board-mount type high-capacity power relay G7L-X

The need for high-capacity products such as electric vehicle chargers and household power storage systems has further increased in recent years.
However, the heat generated by the large current flow will shorten the life of the circuit board of the equipment. Therefore, relays with low contact resistance should be selected.
OMRON has launched a new relay with “low contact resistance of initial 10 mΩ or less” in the high-capacity band of 1000 VDC.
OMRON contributes to solving customers’ heat generation problems with its high-capacity, low-heat generating relays based on ultra-low contact resistance technology.

OMRON contributes to the construction of DC energy systems.

OMRON’s DC switching relays make it possible to construct high-voltage, high-current DC energy systems in a safe, secure, and compact manner.
