Limit switch TZ-8111, pin

The CNTD TZ-8111 limit switch from the TZ-8 series is an industrial mechanical limit switch with a pin (push) piston, designed for accurate and reliable detection of end positions and mechanical stops. The pin design allows direct force transmission without elastic overhang, which ensures unambiguous switching and high repeatability even with frequent cycling.
