Switch Type: Limit switch

The CNTD CZ-8112N is a high-precision roller plunger type limit switch of the CZ series industrial position control switches. Adopting vertical roller plunger actuation structure, this switch features low friction triggering, smooth stroke operation and high positioning repeatability, perfectly suitable for vertical reciprocating stroke limiting and precision mechanical position detection. Built with high-strength zinc alloy die-cast housing and fully sealed structure, it owns IP65 dustproof, waterproof and oil-proof performance. Equipped with a built-in double-spring microswitch mechanism, it delivers stable signal output, excellent vibration resistance and ultra-long service life. It is widely used in industrial automation lines, CNC machine tools, lifting machinery, packaging equipment and other mechanical stroke limit and overtravel protection systems.

- Roller Plunger Structure: Vertical roller plunger design effectively reduces triggering friction, ensures smooth and jamming-free actuation, ideal for frequent vertical reciprocating motion and precision limit control scenarios.

- Heavy-Duty Industrial Housing: High-strength zinc alloy die-cast shell with anti-collision, anti-wear and anti-deformation performance, stable for long-term operation in harsh industrial environments.

- IP65 Full Protection: Integrated sealing structure effectively resists industrial dust, water splash, lubricating oil and humid air, ensuring stable operation in oily and dusty workshops.

- Stable Contact Performance: High-precision double-spring reset mechanism ensures instant switching of NO/NC contacts, no delay or virtual connection during high-frequency cyclic operation.

- Ultra-Long Service Life: Optimized mechanical transmission structure, mechanical life up to 10 million times and electrical life over 500,000 times.

- Universal Standard Installation: Consistent mounting hole size and spacing with CZ/TZ series, compatible with most industrial equipment brackets, easy installation and wiring.

- Strong Environmental Adaptability: Excellent anti-vibration and anti-impact capability, maintaining stable triggering accuracy under dynamic working conditions.
