1.The applications of sensor ?
A: Punch, Machine tool, Automatic controller, Automatic water device, Semi automatic industrial control equipment
2.How to confirm the sensors model ?
A: The buyer need to provide the below information : Voltage NPN/PNP NO/NC/NO+NC Detected object Detected distance
3.How to adjust the distance of the photoelectric switch ?
A: Clockwise make the detected distance increase and anti-clockwise decrease .
4. Difference between photoelectric switch and capacitance type ?
A: (1) They can both detect liquids , but Cm can only be detected through the glass tube or plastic tube , photoelectric switch can not .
(2) The detection distance of the photoelectric switch is larger than the capacitance type

Photoelectric switch Principle of photoeletric switch
The working principle of the photoelectric switch is that when the beam emitted by the emitter is blocked or partly reflected by the object, the beam by the emitter is blocked or partly reflected by the object, the beam receiver whereby makes a judgment and reacts.
