Relays that operate stably even with reduced coil power consumption contribute to energy savings
Renewable energies are necessary to realize a decarbonized society. The widespread use of these power generation devices and the use of DC energy are being introduced into general household and industrial applications.
Along with such trends, relays are required to have higher capacity as the capacity of devices increases, but this requires larger switching capability, which in turn increases the power consumption of the coil.
OMRON contributes to the realization of a decarbonized society by achieving both low power consumption and higher capacity switching of relay coils through its unique design.

Reasons why coil power consumption increases

OMRON contributes to energy savings with three types that reduce power consumption
Latching type
Allows current to flow only when switching ON/OFF.
Example: One-turn latch

Latching relays

G2RK/U

G6BK/U

G6CK/U

G5RL-K/-U

Information on the latching relay lineup and applications is shown on the product.
PWM control type *1
Reduces the time to apply voltage.
*1. Applicable to those whose type name ends with -PW or -PW1.

Low holding voltage type
When the contact is ON, the rated voltage is applied and the voltage in the holding state is lowered.
Example: G6QE

Low holding power relays
