Eaton LS-Titan Limit Switch LS-S11S/RLA, Rotary Lever, Momentary, 1NO+1NC, 400V AC/4A, IP67, Metal 106803

In automated machinery and conveyor systems, position detection must remain reliable even when exposed to dust, moisture, and mechanical stress. The Eaton LS-Titan LS-S11S/RLA limit switch provides a rugged solution for such demanding environments, combining a die-cast metal housing with IP67 sealing to keep contaminants out. Its rotary lever actuator with momentary spring-return action delivers precise signalling for machine control and safety interlock applications.

Who is it for

This limit switch is intended for machine builders, system integrators, and maintenance engineers who need a robust position sensor for industrial automation, packaging equipment, material handling, and similar applications where durability and consistent switching are critical.
