Siemens Limit Switch with Round Plunger Actuator, 1 NO/2 NC Contacts, Metal Housing, IP66/IP67 Rated, 4A, Model 3SE5212-0LC05

Siemens 3SE5212-0LC05 Limit Switch with Round Plunger actuator is designed for precise position detection in demanding industrial applications. Featuring a robust metal housing, this device ensures high mechanical durability and environmental protection with IP66 and IP67 ratings. The snap action contacts provide fast response and reliable switching capability with a rated switching current of 4A.

This limit switch supports 1 Normally Open (NO) and 2 Normally Closed (NC) contacts, enabling versatile control configurations. With a broad operating temperature range from -25°C up to 85°C, it is suitable for harsh conditions encountered in manufacturing, automation, and electrical control panels.

The device uses an M20 x 1.5 conduit entry for secure wiring and installation. Its design includes a round plunger actuator that allows for consistent and exact triggering of switching operations. The mechanical life expectancy of approximately 15 million cycles ensures excellent reliability and long service life.

Additional benefits include easy replacement or mounting of the actuator heads via plug mounting with uniform interfaces. All actuator heads can be rotated in 22.5° increments to suit various installation requirements, reducing mounting time significantly. The integral chlorinated rubber diaphragm enhances functional safety, particularly in cold or aggressive environments.

This limit switch conforms to multiple international standards including UL, RoHS, IEC, EAC, CSA, CE, and CCC, certifying it for quality and safety compliance. It is engineered in Germany to deliver consistent performance in industrial, automation, machinery, and electrical applications.

Features 1 NO and 2 NC snap action contacts for reliable switching. Constructed with durable metal housing suitable for industrial environments. Rated for protection classes IP66 and IP67, ensuring resistance to dust and water.

Operates reliably between -25°C and 85°C operating temperatures. Equipped with M20 terminal entry for secure wiring connections. Mechanical life rated for 15 million cycles for extended durability. Compatible with universal mounting orientations for flexible installation.
