2pcs DC 5V NPN NO M12 4mm Sensor LJ12A3-4-Z/BX Inductive Proximity Sensor Switch for 3D Printer CNC Z Probe auto Bed Leveling
- It is a component widely used in automatic control industry for detecting, controlling, and noncontact switching..
- it can be applied for 3D printer auto leveling, When proximity switch is close to some target object, it will send out control signal..
- As it is capacitive type proximity switch, its detecting object target is not limited to only conductor, but also liquid and even powder things, like plastic, water, glass, oil, etc..
- It's widely used in machine, paper making, light industry for limiting station, orientation taking count, speeding trial ect..
- Brown → +5V, Blue → GND, Black → Signal (Zmin).
