Photoelectrics Through-beam Type PH18CNT..., DC • Miniature sensor range • Range: 20 m • Sensitivity adjustment by potentiometer • Modulated, infraredlight 850 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 • Protection: reverse polarity, short circuit and transients • Cable, plug and pigtail versions • Excellent EMC performance Product Description Ordering Key PH18CNT20PAM1SA The PH18CNT... is part of a family of inexpensive general purpose through-beam sen- sors in industrial standard 18 mm cylindrical andsquare ASS housing. The sensors are useful in applications where high- accuracy detection as well as small size is required. Type Selection 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 outputtype is NPN or PNP and the output switch- ing function is NO and NC.
