• Sensitivity adjustment by potentiometer
• Modulated, red light 625 nm
• Supply voltage: 10 to 30 VDC
• Output: 100 mA, NPN or PNP, N.O & N.C.
• Degree of protection: IP67, IP69K
• LED indication for output, stability and power ON

• Excellent EMC performance
The PA18C.P is part of a fam- ily of inexpensive general pur- poseretro-reflectivesensors in industrial standard 18 mm cylindrical 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 flexible. The output type is NPN or PNP and the output switching function is NO and NC.
