Limit switch TZ-8122, roller 90°

The CNTD TZ-8122 limit switch from the TZ-8 series is a robust industrial mechanical switch with a straight push piston, designed for precise detection of end positions and mechanical stops. The compact design allows installation even in limited space, while the straight piston ensures unambiguous and repeatable switching without spring preload.
