This tool length sensor works not like most, in the low price segment, offered sensors with a simple tracer. Instead it has a precise micro tracer inside, which is operated from above with a tappet. Thereby a high repetition accuracy is ensured.
The switch is configured as a normally closed switch,to ensure saftey. If wanted, it can be easily reconfiguerd to a normaly open contact. The sensor can be screwed to your tabke with 2 M4 Screws (Not included)
