G7L-2A-BUBJ-AC100-120 — relay coil in the G7L power relay line
The Omron G7L-2A-BUBJ-AC100-120 is a general-purpose relay from the G7L series, built around a 100-120 VAC coil and the same footprint as the rest of the G7L power-relay family — meaning it drops into existing panel layouts that already use the G7L socket and mounting pattern. General-purpose relays in this class are used to switch higher-current loads (heaters, motors, solenoids, lighting contactors) from a low-power control circuit — the coil draws a small control-side current and the contacts carry the panel-side load, which is why the G7L sits at the boundary between control wiring and power wiring rather than next to signal-level logic relays.
Handling and panel fit
Mounting is via the standard G7L socket — confirm the socket part number on the BOM matches the coil variant before energising, because a mismatched socket wiring pattern is the most common commissioning fault on this relay family.
