Precision tool length sensor PNP NC with 29 mm probe incl. plastic holder
NPN or PNP sensor:
How to choose the right one?
The tool lenght sensor build with an inductive sensor are available with either NPN or PNP logic. They all need a power supply in order to work (usaully 24V), but the type of sensor depends of your wiring and controller board.
NPN : the sensor produces a negative signal during an "on" state
PNP : the sensor produces a positive signal during an "on" state
The high quality tool length sensor is characterized by a very good guidance of the probe.
The large steel sensing surface was planned to achieve a very precise measurement. Due to the inductive sensor a very high repeatability is possible.
