Omron G2R-2-SND 12VDC (S) Relay Socket: Technical Overview

The Omron G2R-2-SND 12VDC (S) relay socket is a plug-in general purpose relay designed for 12 VDC control circuits. It combines DPDT switching, LED indication, mechanical indication, and a coil suppressor feature, making it a practical option for compact industrial and electrical control applications.

Technical Profile

This model operates with a 12 VDC coil and provides a 5 A rated carry current. The DPDT contact structure allows two separate circuits to be controlled at the same time. The SND version includes coil suppression, which is especially useful in DC control systems where coil de-energization can create voltage spikes.

Why Coil Suppression Is Important

In DC relay circuits, suppressing reverse voltage helps protect nearby electronics such as PLC outputs, transistor drivers, control boards, and monitoring modules. The Omron G2R-2-SND 12VDC (S) relay socket is therefore useful where the relay is connected to sensitive control equipment and clean switching behavior is required.

Common Use Cases

This relay is suitable for 12 VDC control panels, compact automation systems, machine interfaces, auxiliary switching circuits, alarm equipment, and low-voltage relay logic. The plug-in format improves maintenance efficiency, while the indicator features support clear operational visibility.

FAQ

What is the coil voltage of Omron G2R-2-SND 12VDC (S)?

It operates with a 12 VDC coil and should be used in circuits designed for that voltage level.

What does SND mean in this relay family?

In this context, SND identifies a relay type with LED indication and coil suppression for DC operation.

Does this relay help protect PLC outputs?

The built-in coil suppression can help reduce coil-related voltage spikes, which is beneficial when driving the relay from electronic outputs.

Is it suitable for two-circuit switching?

Yes. Its DPDT arrangement allows two separate circuits to be switched by one relay coil.

Can it be replaced easily during maintenance?

Yes. Its plug-in socket design allows the relay body to be removed and replaced without rewiring the complete circuit.
