Siemens 3SE5 Safety Hinge Switch 1 NO/2 NC Metal Housing IP65 230V DC 400V AC 10A 3SE5112-0LU22

Siemens 3SE5112-0LU22 Safety Hinge Switch is engineered for reliable mechanical monitoring of hinged doors and flaps in industrial automation and safety systems. This switch provides excellent protection against tampering due to its fixed, positive pivot point connection between the switch and door hinge. Designed with a robust metal housing and rated to IP65, the switch withstands challenging environmental conditions commonly encountered in manufacturing, electrical enclosures, and industrial safety applications.

The hinge switch offers 1 normally open (NO) and 2 normally closed (NC) snap-action contacts to enable simultaneous shutdown and signaling. It supports contact voltages of 230V DC and 400V AC with a maximum current rating of 10A, making it suitable for a wide range of electrical control circuits. Its compact dimensions (78mm length, 4mm width, and 50mm shaft length) facilitate mounting in tight spaces and varied enclosure designs.

Operating temperature ranges from -25°C to 85°C ensure compatibility with industrial environments requiring resilience across temperature fluctuations. The switch incorporates an M20 x 1.5 mm cable entry size with screw terminal connections for straightforward and secure wiring, reducing installation time by approximately 20 to 25%.

Compliance with EN 50047 and EN 50041 standards reflects its construction to reliable industry specifications. It offers protection up to Category 4 (EN 954-1) and has safety integrity level up to SIL 3 (IEC 62061), ensuring high safety performance critical in applications such as industrial automation, machine guarding, and process control. The actuator head can be rotated in 22.5° increments to accommodate specific installation angles and operational needs.

Mechanical life expectancy of 1,000,000 operating cycles underlines its durability for continuous and demanding use cases. This safety hinge switch is ideal for industries including manufacturing, electrical cabinets, automation, HVAC, and water treatment facilities requiring dependable safety interlock solutions.
