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..

..., so it does not rely on additional air machine, perfect for Mobile Automotive Repair! The smoke can be produced within 7-15 seconds, dramatically reducing diagnostic time. Smoke output value: 1-6L/min..
【Flow Meter & Pressure Gauge】According to the pressure of the detection pipeline, it is controlled with a flowmeter to more effectively protect the pipeline from damage. By observing the pressure gauge, you can determine whether the pipeline is leaking more quickly and accurately. Usually the pressure gauge continues to rise, indicating that there is no problem with the pipeline. If the pressure gauge continues to decrease, Explain that the pipeline leak needs to be repaired..
【EVAP Detection】American cars that began production in 1996 are equipped with EVAP service ports.
in most American cars, the EVAP service port is usually located in the engine compartment, but the EVAP service port of some special models may be located in other locations. Open the plastic cover of the EVAP service port, then use the spool wrench to remove the check valve clockwise, then install the EVAP service port adapter, and introduce smoke from the port into the EVAP leak dete....
