P11DMB-FULD-P2 - Toolsetter - Ø10 Tip - Switch NC- LED - IP67 - 2M Protective Tube

Ultra-high precision mechanical switch. If you have an ultra-precision application and are experiencing signal drift issues. This is common with inductive proximity sensors. Then this type of switch can solve these problems. These sensors are used in industrial automation, but also in precise CNC machines. Usually for tool length measurement. Because the repeatability is 0.5 microns or less, highly accurate home measurement is possible. Since there is no signal drift, such switches can also be used for temperature compensation. By default, the switch has an IP67 protective structure and can be used in harsh environments with water, emulsion or oil. We tested these switches in CNC grinders and they work very well, and much more accurately than inductive sensors we previously used in that machine. The improvements compared to an inductive sensor are approximately a factor of 10. The repeatability is 0.0005 mm or less. So that's half a micron!

This device is also a good basis for making a tool length meter, to measure the tool length in the vertical direction. On CNC machines this is also called a toolsetter. This unit is extremely small and compact, making it also suitable for small CNC machines.
