Why choose it

The LSM-11 combines rugged construction with precise switching. Its die-cast metal housing withstands mechanical stress, while the IP66/IP67 rating ensures protection against dust and water ingress. The snap-action mechanism provides fast and reliable contact changeover, reducing the risk of arcing and extending contact life.

Ideal use cases

• End-of-travel detection on linear actuators
• Presence sensing in automated assembly lines
• Safety interlock applications on machine guards
• Position feedback on valves and dampers

Good to know

The switch is designed for screw mounting and features screw terminals for secure wiring. It complies with IEC/EN 60947-5-1 and VDE 0660 Part 200 standards, ensuring compatibility with industrial control systems.
