OMRON G5V-2-H1-DC12V Relay

Updated: 2026-08-06

Overview

The G5V-2-H1-DC12V is a compact, single-pole double-throw (SPDT) relay designed for low-power switching applications. It operates at 12V DC and is commonly used in industrial, automotive, and electronic control systems. The relay is known for its reliability, long service life, and ability to handle moderate electrical loads. Manufactured with a durable plastic housing and metal contacts, the G5V-2-H1-DC12V is suitable for a variety of environments. Its small footprint makes it ideal for space-constrained applications, while its high switching capacity ensures consistent performance in demanding conditions.

Structure and Working Principle

The G5V-2-H1-DC12V relay consists of a coil, armature, and SPDT contacts. When a 12V DC voltage is applied to the coil, it generates a magnetic field that moves the armature, switching the contacts between the normally open (NO) and normally closed (NC) positions. The relay's internal structure is designed to minimize arcing and wear, ensuring long-term reliability. The contacts are made of high-quality materials to withstand frequent switching cycles. The compact design allows for easy integration into circuit boards or control panels.
