Datasheet G8N-1 Specification

G8N

Micro-mini PCB relay for automobile use

High-density design
(smallest class in the
industry)
Half-size in comparison
with the existing type

(Omron G8QN)

• Super-slim width (7.2mm). Good for parts layout.

• Even at a small size, high-wattage switching is

possible due to the contacts and heat-release
design. 100,000 times at 14VDC/25A (motor lock).

■ Purpose

• DC motor control for automobile parts (Door lock motor, power window motor, wiper motor, washer motor, sunroof motor, etc.)

• Flasher lamp (indicator or hazard)
