Omron G2R-1-SN 12VAC (S) Plug-in Relay Guide

The Omron G2R-1-SN 12VAC (S) plug-in relay is a general-purpose relay for low-voltage AC control applications. It is commonly used in automation panels, control cabinets, test systems, signal switching circuits, and equipment where 12 VAC control voltage is preferred.

As part of the Omron G2RS relay family, this model combines a compact plug-in design with practical diagnostic features. It uses a 1-pole SPDT contact arrangement, allowing one circuit to switch between normally open and normally closed states. This makes it useful for control logic and auxiliary switching.

Technical Profile

The G2R-1-SN 12VAC (S) operates with a 12 VAC coil and provides a rated carry current of 10 A. The plug-in terminal structure supports socket-based installation, which is valuable for maintenance-focused panel designs. Instead of replacing wiring, technicians can remove and replace the relay body from the socket.

The relay includes LED and mechanical indication. These features are not cosmetic; they help reduce troubleshooting time by making relay status visible. The transparent case also supports visual inspection inside the relay body.

Best-Fit Applications

This relay is suitable for low-voltage AC control panels, equipment testing circuits, auxiliary control wiring, machine interfaces, and small automation systems. It is often selected when users need a trusted electromechanical relay format with easy replacement and clear operating indication.

Omron G2R-1-SN 12VAC (S) FAQ

What makes Omron G2R-1-SN 12VAC (S) different from DC versions?

The main difference is the coil operating voltage. This model uses a 12 VAC coil, while DC versions are designed for direct-current control circuits.

Is this relay suitable for low-voltage control systems?

Yes. Its 12 VAC coil makes it appropriate for low-voltage AC control applications.

What does the SN designation indicate?

In this relay family, SN versions include visual indication features such as LED and mechanical indication.

Can it switch both normally open and normally closed circuits?

Yes. Its SPDT contact structure provides both NO and NC switching paths through one changeover contact.

Why is socket mounting useful?

Socket mounting allows faster replacement, cleaner panel wiring, and easier maintenance compared with permanently wired relay formats.
