1.When you use KJT’s photoelectric sensor and inductive proximity sensor, the following subject should be noticed: 

Ensure the working voltage is 10-30VDC or 90-250AC.



Required the sensing distance and the material of detecting objects.



For photoelectric sensor ensure it is available through beam and reflection.



Ensure it is NPN or PNP output.



2.How do I choose the most suitable photoelectric sensor?

To make sure your sensing distance and object’s size, color and material.



3.Why photoelectric sensor and capacitive proximity sensor have happen wrong action or non-output?

Ensure the mix detecting distance of your product and the detect object size cannot be smaller than the minium size 18*18mm.



Ensure the material of detecting objects.



Usually, the wrong action is happened when you use the wrong types of NPN or PNP and wrong types of sensors.




4.What’s the componet’s protective circuit?

It will active the protective circuit or reverse polarity protection to reduce the damage caused by the wrong operation.
