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).

Test objects: metal, and non-metal such as plastic, glass, water, oil, etc..
Can also be used in frequency counters, frequency pulse generator, liquid level control and processing procedures for the automatic convergence..
It is a component widely used in automatic control industry for detecting, controlling, and non-contact switching..
The detection distance varies with the conductivity, dielectric constant, water absorption rate and volume of the tested body, and a large detection distance can be obtained for the grounded metal..
When proximity switch is close to some target object, it will send out control signal..
