Limit switch TZ-8112, straight roller

The CNTD TZ-8112 limit switch from the TZ-8 series is an industrial mechanical limit switch with a straight roller piston, designed for accurate and repeatable detection of end positions and mechanical stops. The roller design reduces friction and wear when contacting moving parts, which ensures smooth switching and long service life even at high cycle rates.
