This arrived dead. I decided to repair it rather than return. The internal mechanism is two microswitches so the primary sensor is not a piezoelectric as implied by the circuit diagram. One of the wires was loose. I resoldered them all as they were soldered at an angle and almost short circuiting and added some insulation. Also adjusted the microswitch position. Mechanically it is not terrible.

This is not a Normally Open tool height sensor like the title said. I have tested it and both the main and the overtravel contacts are Normally Closed. I have paid premium price thinking that I am getting the correct sensor. Now my machine build is delayed! .... False advertising. Buyers beware!

not as described. this tool setter doesn't have a led indicator or set screws to level the touch off pad. also the pad has a bit of wiggle to it as well.
