Limit switch A compact, rugged mechanical switch that converts a physical position or contact with an actuator into an electrical signal for control systems. It detects endoftravel or a specific position in machinery and signals the control logic to start, stop, or change motion. Key benefits Endoftravel protection: prevents overtravel and potential damage to equipment. Reliable position feedback: provides a repeatable signal for precise cycle control. Easy integration: designed for standard control inputs and simple wiring. Durable build: engineered for repeated actuations in industrial environments. Flexible actuation options: available with different actuator types to suit various mechanisms. Compatibility and electrical options Intended for standard control circuits; exact electrical ratings and contact configurations vary by model. Wiring and connection methods follow common industrial practices; check the specific model for terminal type and layout. Contact configurations and operating voltages are model dependent; review the product specification for your version. Physical characteristics Size: compact form factor suitable for tight installation spaces. Materials: housing available in metal or tough plastic versions; internal contacts designed for durability. Mounting: common mounting holes or brackets; pattern and torque requirements vary by model. Environment: some versions offer sealing and higher enclosure protection; verify IP rating and suitability for your environment. Performance Actuation: mechanical action with rapid response; depend on actuator type and travel distance. Life expectancy: designed for long cycle life under typical use; expected life depends on model and conditions. Noise and bounce: designed to minimize electrical noise and contact bounce in control circuits. Use scenarios Conveyor system endofline detection: place at the end of travel to stop the belt when a item reaches the end, reducing jams and spill risk. Home or reference position in automation: use as a limit reference to establish home positions for robotic arms or CNC machines. Safety interlock for access gates: monitor guard closure to enable machine operation only when guards are in place, enhancing operator safety. How to choose Determine required actuation type (plunger, lever, or roller) and the needed travel. Confirm electrical requirements (voltage, current, and contact configuration) for your control system. Check mounting pattern, enclosure rating, and actuator length to fit your installation. Review the specific model's materials and environmental ratings to match operating conditions.
