CNTD C4B-4105N Roller Lever Limit Switch

1NC/1NO Snap-action | IP66 | AC 250V 6A | -20 to +80°C | CE/CCC Certified

Product Overview

The CNTD C4B-4105N is a professional-grade roller lever limit switch (vertical type, metal roller) engineered for position detection and machinery safety in industrial automation. Featuring 1NC/1NO snap-action contacts, IP66 protection, and a rugged flame-retardant housing, this micro switch delivers reliable switching in demanding environments. The built-in forced open action device (NC contacts) disconnects the circuit even if contacts weld, providing critical safety assurance. Rated AC 250V 6A with 500,000 electrical cycles, it is CE and CCC certified for full compliance with European machinery standards.
