Product Description
Ordering Key
The PH18CNB20... is part of a family of inexpensive gener- al purpose diffuse reflective sensors with backgrund sup- pression in industrial standard
18 mm cylindrical and square
ABS housing.
The sensors are useful in applications where high- accuracy detection as well as small size is required.
Compact housing and high power LED for excellent performance-size ratio.
The potentiometer used for adjustment of the sensitivity makes the sensors highly flex- ible. The output type is NPN or PNP and the output switch- ing function is NO and NC.
