Limit switch TZ-8109, adjustable arm with metal roller

The CNTD TZ-8109 limit switch from the TZ-8 series is a robust industrial mechanical limit switch with an adjustable arm ending in a metal roller. This design is designed for precise position detection during lateral or oblique approach, where smooth contact, low friction and high mechanical resistance are required. The adjustable arm allows easy adjustment of the switching point to suit the specific application.
