Omron SS-5GL2 Limit Switch

Omron has long been a trusted brand for precision-engineered components, providing dependable control solutions for industrial and commercial automation. The SS-5GL2 is a key member of the Omron Subminiature Basic Switch family, designed for reliability, compact integration, and precise actuation. Engineers and OEMs rely on this model for its long mechanical life, high durability, and consistent electrical performance across varied environmental conditions. Compact yet powerful, the Omron SS-5GL2 delivers stable switching performance suitable for industrial controls, appliances, and general machinery.

The SS 5GL2 employs a long hinge lever actuator, which allows smooth operation and low mechanical stress during switching. Its solder terminal configuration provides simple wiring and solid electrical connections. Featuring an operating force of 0.74 N (max.) and a release force of 0.029 N (min.), the switch ensures precise and responsive actuation. The pretravel of 5.2 mm, overtravel of 1.2 mm, and movement differential of 0.25 mm make this model ideal for applications that demand both sensitivity and repeatability. The operating position of 15.7 ± 1.2 mm provides flexibility and accuracy in assembly design, particularly in compact automation panels or precision control systems.

Built for reliable electrical performance, the Omron SS 5GL2 is rated for 5 A at 125 VAC and 3 A at 250 VAC. It offers an insulation resistance of 100 MΩ minimum at 500 VDC and a low contact resistance of 100 mΩ (max.). With dielectric strength of 1,000 VAC between terminals and 1,500 VAC between terminals and ground for one minute, this switch ensures both operator safety and system stability. The design supports long-term operation with reduced arcing and consistent contact integrity, making it suitable for use in control logic circuits, limit sensing, and mechanical feedback systems.

In durability testing, the SS-5GL2 demonstrates exceptional longevity, offering a mechanical life of 10 million operations and an electrical life of 100,000 operations at rated load. It functions reliably within ambient temperatures of –25°C to +85°C and up to 85% relative humidity. This rugged construction enables consistent performance even in challenging factory conditions with vibration, heat, and humidity. The Omron SS-5GL2 Limit Switch is frequently integrated into industrial robots, small conveyors, and safety interlock systems due to its superior mechanical response and compact footprint.

The Omron SS-5GL2 is widely used by automation engineers, panel builders, and equipment manufacturers who require a long-lasting, space-saving micro switch. It fits easily into tight assemblies without sacrificing performance or safety standards. The long hinge lever design provides added actuation distance, giving operators greater flexibility in configuring switch positions. Maintenance engineers value its ability to maintain high accuracy over millions of cycles, reducing replacement frequency and downtime. Wholesalers, dealers, and distributors continue to recommend this switch for reliable integration in diverse automation projects.

For applications needing a similar switch with a standard hinge lever actuator, the Omron SS-5GL serves as an excellent alternative within the same product series. Together, the SS-5GL and SS-5GL2 cover a wide range of actuation requirements in machinery, safety interlocks, and control panels. Combining proven Omron engineering with compact, high-precision design, the Omron SS-5GL2 Limit Switch stands as a reliable choice for modern automation. With its extended mechanical life, stable electrical characteristics, and rugged housing, the SS-5GL2 remains a benchmark in subminiature switch technology for industrial automation applications.
