The CNTD CZ-8109N is a high-precision universal flexible roller lever type limit switch of the CZ series industrial position control switches. Adopting a special omnidirectional movable swing lever structure, this model supports multi-angle and multi-directional free triggering, which is suitable for complex motion trajectories and irregular stroke limiting scenarios that ordinary fixed lever switches cannot adapt to. With high-strength zinc alloy die-cast housing and fully integrated sealing design, it achieves stable IP65 dustproof, waterproof and oil-proof protection grade, adapting to various ordinary and harsh industrial workshop environments. Equipped with a built-in precision double-spring microswitch mechanism, it features sensitive response, stable signal output, excellent vibration resistance and ultra-long mechanical and electrical service life. It is widely applied in automated production lines, CNC machine tools, lifting equipment, conveying machinery, textile machinery and special industrial equipment for position detection, stroke limitation and overtravel safety protection.

- Heavy-Duty Industrial Housing: High-strength zinc alloy die-cast shell with outstanding anti-collision, anti-wear and anti-deformation performance, ensuring long-term stable continuous operation in complex industrial environments.
- IP65 Full Environmental Protection: Integrated fully sealed structure effectively isolates industrial dust, lubricating oil, humid air and splashing water, preventing internal mechanism contamination and failure.
- Stable Contact Performance: Precision double-spring reset mechanism ensures rapid and reliable NO/NC contact switching without signal delay or virtual connection during high-frequency cyclic operation.
- Ultra-Long Service Life: Optimized internal transmission structure reduces mechanical friction and wear, achieving mechanical life up to 10 million times and electrical life over 500,000 times.
- Universal Standard Installation: Consistent mounting hole size and spacing with all CZ/TZ series limit switches, compatible with mainstream industrial equipment brackets for simple and fast installation and wiring.
- Strong Environmental Adaptability: Excellent anti-vibration and anti-impact performance, maintaining accurate and stable triggering accuracy under dynamic and complex working conditions.
