The XCKJ161H29 limit switch features a metal end plunger, dual contacts (1 normally closed and 1 normally open), a snapaction mechanism, and M20 mounting. It is designed for reliable endoftravel sensing in industrial equipment with a robust metal body and actuation that delivers fast and repeatable switching. Key benefits Robust metal construction for durability in industrial environments. Dual contact arrangement (1NC + 1NO) provides flexible control logic in a single device. Snapaction operation delivers fast, decisive switching with reduced contact wear. M20 mounting supports straightforward installation with standard hardware and panels. Metal end plunger offers durable, precise actuation and long service life. Key attributes Model: XCKJ161H29 Type: limit switch with metal end plunger Contacts: 1 normally closed (NC) and 1 normally open (NO) Action: snap action Mounting: M20 thread Body/material: metal construction Application suitability: reliable endoftravel sensing, position detection, and signaling in automation systems Actuator: metal end plunger for durable actuation Applications and use cases Endoftravel sensing on a conveyor, robotic arm, or automated machine to trigger a stop or reposition sequence. Safety interlock or guard door sensing in packaging or manufacturing lines, using the NC contact for failsafe signaling. Position reference or home switch in CNC or other automation equipment, leveraging the NO contact for active indication. Notes on integration The 1NC + 1NO configuration allows wiring flexibility for control circuits, enabling both default and activestate signals from a single device. The M20 mounting thread facilitates compatibility with common mounting brackets and panels used in industrial control setups. The metal body and metal end plunger are designed to withstand repeated actuation in demanding environments while maintaining reliable operation.
