TZ3104 IP67 4Wire Limit Switch — SPDT (NO + NC), Copper Wire, 3 Meter Cable (1 PCS) A compact, rugged limit switch designed for reliable position sensing and endoftravel detection in wet or dusty environments. The TZ3104 provides both normally open (NO) and normally closed (NC) SPDT contacts and comes with a 3 meter copper conductor cable for flexible installation and wiring. Key benefits Watertight and dustproof: IP67 rating protects the switch from dust ingress and temporary immersion in water, reducing failure risk in harsh environments. Dualcontact flexibility: SPDT configuration gives both NO and NC contacts, allowing easy integration into different control schemes without swapping parts. Readytoinstall wiring: 4wire copper cable (3 m) simplifies routing and makes the switch suitable for installations where the controller or relay is not nearby. Durable solution for position sensing: Designed to reliably detect travel limits, stops, or mechanical positions and communicate them to controllers, relays, or safety systems. Key attributes Model: TZ3104 Quantity: 1 PCS Contact type: SPDT (provides both NO and NC) Wiring: 4wire cable with copper conductors Cable length: 3 meters Environmental protection: IP67 Applications / Typical use cases Conveyor systems: Detect endoftravel or stalled carriers and trigger motor stop or alarm logic. Doors, gates and actuators: Confirm fully open or closed positions for automatic doors, industrial gates, or linear actuators. Industrial machinery and safety interlocks: Provide reliable limit detection for packaging machines, presses, or any application requiring failsafe position feedback in wet/dusty conditions. Installation and practical notes The unit is supplied with a 3 m, 4wire copper cable for straightforward connection to controllers, relays, or monitoring devices. Confirm wiring scheme with your system before powering. IP67 protection reduces the need for additional sealing in exposed locations, but provide mechanical strain relief for the cable and mount the switch where physical impact is minimized. Test both NO and NC functions during commissioning to ensure correct logic in your control system. This TZ3104 limit switch offers a simple, robust option for position sensing where environmental protection and flexible wiring are required.
