Description
The CNTD TZ-8104 limit switch from the TZ-8 series is a robust industrial mechanical switch designed for precise detection of end positions and mechanical stops. The vertical design with a metal lever and roller allows for smooth movement transmission, a larger working range and reliable function even under repeated mechanical loads in demanding operating conditions.
