20mm Inductive Proximity Sensor Switch Detector NPN NO DC 6-36V 300mA 3-wire SC-3020A

It is a component widely used in automatic control industry for detecting, controlling, and noncontact switching. When proximity switch is close to some target object, it will send out control signal.
It is widely used in machine, paper making, light industry for limiting station, orientation taking count, speeding trial ect.

Note: 
1.The Optimum voltage range is 6V-36VDC.
2.It is recommended that the actual detection distance is less than 70% of the detection distance on the name plate. 
3.When wiring, do not energized, strictly according to the wiring diagram.
4.Only metal objects can be detected, especially for iron metal can be better detected, but the choice of non-iron metal, the detection distance will be greatly reduced.
