ME8166 Travel Limit Switch — 1pc, AC250V, NO / NC, SelfReset Touch Controller (Limit Open) A reliable, easytoinstall travel limit switch for position sensing and simple control tasks. The ME8166 combines normally open (NO) and normally closed (NC) contacts with a selfresetting touch actuator to give clear, repeatable endoftravel signals for AC control circuits up to 250V. Key benefits Simple position and endoftravel detection: Detects mechanical travel reliably and translates it into a clear electrical signal using NO and NC contacts. Reduces maintenance and downtime: Selfreset touch action returns the switch to its resting state automatically after actuation. Flexible wiring options: Provides both NO and NC outputs so it can be used with a variety of control layouts and safety interlocks. Singlepiece supply: Sold as 1pc for quick replacement or installation. Key attributes Model: ME8166 Voltage rating: AC250V Contact configuration: NO (normally open) and NC (normally closed) Type: Travel limit switch / touch controller Feature: Selfreset (automatic after actuation) Pack quantity: 1pc Function: Limit open / travel detection How it solves problems Converts mechanical motion into reliable electrical signals to stop, start, or interlock equipment at a precise travel point. Dual contact options (NO and NC) let you choose whether to signal on closure or on break, matching your control logic without extra relays. Selfresetting action removes the need for manual resetting after each trip, simplifying operation in repetitive cycles. Typical applications Industrial machinery endoftravel detection: Use as a limit switch on conveyor stops, guide rails, or actuated arms to prevent overtravel. Door, gate, and actuator controls: Provide reliable position feedback for doors, gates, or linear actuators to trigger stop commands. Small equipment and automation projects: Use in hobbyist CNC machines, robotics, or simple control panels where compact, repeatable travel sensing is required. Installation and compatibility notes Rated for AC circuits up to 250V; match wiring and protective components to your system's voltage and current requirements. Provides both NO and NC contacts for easy integration into existing control logic. Sold as a single unit (1pc).
