What are the key features of G5V-1 12DC?
- 12 V DC coil with SPDT (1C) contacts enables single-pole signal switching from standard 12 V relay driver stages
- Rated for 1 A at 125 V AC or 30 V DC, handling a broad range of signal-level loads in control and automation circuits
- Through-hole PCB mount with compact DIP-style footprint simplifies integration into relay driver boards and prototype assemblies
- Non-latching design returns contacts to the de-energised state on power loss, providing a built-in fail-safe behaviour
What is G5V-1 12DC used for?
The G5V-1 12DC is widely used in home appliance control boards, industrial automation panels, and telecommunications switching equipment where a compact, reliable SPDT relay is needed to control loads up to 1 A at 125 V AC from a 12 V DC power bus. Its through-hole construction simplifies both prototype assembly and standard PCB production, and the non-latching configuration suits safe-state circuits that must return to a known contact position whenever power is removed. The small footprint and 12 V coil compatibility make it a practical choice for relay driver circuits built around transistors or dedicated relay driver ICs.

Frequently Asked Questions
What coil voltage and contact switching rating does the Omron G5V-1 12DC provide?
The G5V-1 12DC operates on a 12 V DC coil and provides an SPDT (1C) contact arrangement rated for 1 A at 125 V AC or 30 V DC. Its through-hole body is optimised for PCB signal relay applications where the driver stage outputs a 12 V coil current of approximately 33 mA to switch low-power loads reliably.
Which control and automation circuits take advantage of the SPDT contacts in the G5V-1 12DC?
Home appliance motor controllers, industrial PLC output modules, and telecommunications line-switching panels all benefit from the G5V-1 12DC's SPDT contacts, which provide both normally-open and normally-closed switching paths from a single 12 V DC coil. The 1 A contact rating at 125 V AC covers small motors, solenoid valves, LED indicators, and alarm buzzers under typical signal-relay duty conditions.
How does the through-hole package of the G5V-1 12DC simplify prototype and low-volume PCB assembly?
The through-hole format of the G5V-1 12DC fits standard 2.54 mm pitch PCB pads and relay sockets, allowing the relay to be hand-soldered or inserted into DIP sockets during prototyping without custom SMT land patterns. The 12 V DC coil interfaces directly with common NPN transistor driver stages powered from 12 V supplies, eliminating a voltage converter and keeping the driver circuit to just a single transistor and flyback diode.
When should engineers choose the G5V-1 12DC over the 5 V coil version for relay driver design?
The 12 V DC variant is the better choice when the system already provides a 12 V supply rail, which is typical in automotive-adjacent, building-automation, and industrial equipment powered from 12 V DC buses. Using a 12 V coil avoids the power loss of a linear regulator stepping 12 V down to 5 V, while the contact rating remains identical at 1 A, 125 V AC, preserving the same load-switching capability across both coil-voltage variants.
