Photoelectrics Diffuse-reflective, Background Suppression Type PA18CAB20... • Miniature sensor range • Range: 200 mm • Sensitivity adjustment by potentiometer • Modulated, red light 625 nm • Supply voltage: 10 to 30 VDC • Output: 100 mA, NPN or PNP preset • Make and break switching function • LED indication for output and power ON • Protection: reverse polarity, short circuit and transients • Cable and plug versions • Excellent EMC performance • Excelent colourmatching Product Description Ordering Key PA18CAB20NAM1SA The PA18CAB20... is part of a family of inexpensive general purpose diffuse reflective sensors with backgrund sup- pression in industrial stan- dard 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 per- formance-size ratio. The potentiometer used for adjustmentof the sensitivity makes the sensors highly flexible. The outputtypeisNPN or PNP and the output switcing function is NO and NC.
