CNTD C4N-4108N Safety Limit Switch

1. Product Overview

The CNTD C4N-4108N is a compact safety limit switch from the C4N-N Series, engineered for precise position detection and reliable switching in industrial automation. It features an adjustable metal roller lever (resin roller) with snap-action 1NC/1NO contacts and a forced-disconnect function on NC contacts — ensuring the safety circuit opens even if contacts weld. Sealed to IP67 with Class II double insulation, the metal housing resists dust, water jets, and harsh factory environments. Built to EN 60947-5-1, it delivers consistent performance over hundreds of thousands of operations.
