G5V-1-DC5
Overview
The G5V-1-DC5 is a compact Omron signal relay with a 5 V DC coil intended for low-power switching and space-constrained applications. It is a small-footprint electromechanical relay commonly used where signal-level switching or simple isolation is required. Its low coil voltage makes it convenient to drive from standard logic-level electronics with an appropriate driver stage.
Why Choose This Part
Compact size and a 5 V coil make the relay easy to integrate into 5 V systems and breadboard/PCB prototypes. As an Omron part, it offers predictable electromechanical behavior and widespread availability. It is well suited for low-current switching where the robustness of a mechanical contact and electrical isolation are required.
Applications
Getting Started
Consult the Omron datasheet for exact pinout, coil current, and contact ratings before use. Drive the coil with a transistor, MOSFET, or a dedicated relay driver and include a flyback diode or snubber to protect the driver. For easy replacement during development, use a relay socket or leave footprint room on the PCB.
