Omron MY2-GS-R DC12 General Purpose Relay Technical Guide
The Omron MY2-GS-R DC12 general purpose relay is a compact plug-in relay designed for low-voltage DC control circuits. It features an 8-pin plug-in structure, DPDT contact configuration, mechanical indicator, and 12 VDC coil. Omron identifies this model as a MY series relay with plug-in terminals, while distributor data also lists DPDT contacts, silver contact material, 20 ms operate and release times, and socketable mounting. :contentReference[oaicite:1]{index=1}
Technical Overview
This model is useful when a control circuit operates on 12 VDC and requires reliable switching between two independent contact paths. Its DPDT design allows one coil input to control two poles, which is valuable in control panels, alarm systems, signal routing, low-voltage automation, and interface circuits.
The relay is non-latching, meaning the contacts return to their default state when the coil is de-energized. This behavior is important for safety logic, resettable controls, and circuits where the relay should only remain active while voltage is present at the coil.
Electrical Characteristics
The MY2-GS-R DC12 uses a 12 VDC coil. Omron’s related MY2 DC12 data lists a coil current of 72.7 mA and a coil resistance of 165 ohms. The contact form is DPDT, contact material is Ag, and the terminal structure is plug-in. These details make the relay suitable for compact panel applications where predictable control behavior is required.
In practical use, the 12 VDC coil makes this relay relevant for battery-backed systems, control boards, low-voltage machine panels, and auxiliary switching networks. However, the load connected to the contacts must always remain within the approved relay rating.
Installation and Service Benefits
The plug-in design is one of the strongest practical advantages of this relay. Instead of replacing wiring, technicians can remove the relay from a compatible socket and install a new unit quickly. This approach is especially helpful in production environments where long downtime is costly.
The mechanical indicator also supports field maintenance. A technician can confirm relay actuation visually before checking downstream wiring, sensors, or controlled devices. This small feature can save time during fault isolation.
Common Applications
The Omron MY2-GS-R DC12 relay can be used in 12 VDC automation circuits, test benches, control panels, low-voltage switching modules, monitoring equipment, interface relays, and auxiliary machine logic. It is especially useful where two contact paths must be controlled by one coil signal.

Omron MY2-GS-R DC12 FAQ
What is the coil voltage of the Omron MY2-GS-R DC12?
The coil voltage is 12 VDC, making it suitable for low-voltage DC control circuits.
Is the Omron MY2-GS-R DC12 a latching relay?
No. It is a non-latching relay, so the contacts return to their normal position when the coil is no longer energized.
What does the 8-pin plug-in design provide?
The 8-pin plug-in format supports socket mounting, easier replacement, and cleaner control panel maintenance.
Can this relay switch two circuits at the same time?
Yes. Its DPDT contact form allows two separate poles to switch from the same coil operation.
What should engineers verify before using it?
They should verify the 12 VDC supply, contact load, socket compatibility, wiring layout, environmental conditions, and expected switching frequency.
