Eaton LSM-11S interruptor de fim de curso, alavanca de rolete, 1NO+1NC, 6A, IP66/IP67, amarelo 266140

In automated machinery, a limit switch must signal position reliably through millions of cycles, even when dust, moisture, or washdowns are present. The Eaton LSM-11S provides that signal with a snap-action contact block and a sealed thermoplastic housing rated IP66 and IP67.

Who is it for

Maintenance engineers and machine builders who need a compact, base-mounted position switch for conveyors, guards, or linear actuators. It suits applications where the switch is exposed to splashing water or dusty air, and where the actuating mechanism is a roller lever following a cam or moving part.

Tips

Mount the switch so the roller contacts the actuating surface tangentially, not head-on, to avoid side loading the lever. Use a flexible conduit or cable gland with M20 thread to maintain the IP rating at the entry point.
