Photoelectrics Through-beam Type PH18CNT..., DC • • • • • • • • • • •
Product Description The PH18CNT... is part of a family of inexpensive general purpose through-beam sensors in industrial standard 18 mm cylindrical and square ABS housing. The sensors are useful in applications where highaccuracy detection as well as small size is required.
Miniature sensor range Range: 20 m Sensitivity adjustment by potentiometer Modulated, infrared light 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
Ordering Key
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.

* The IP69K test according to DIN 40050-9 for high-pressure, high-temperature wash-down applications. The sensor must not only be dust tight (IP6X), but also able to withstand high-pressure and steam cleaning. The sensor is exposed to high pressure water from a spray nozzle that is fed with 80°C water at 8'000– 10'000 KPa (80–100bar) and a flow rate of 14–6L/min. The nozzle is held 100 –150 mm from the sensor at angles of 0°, 30°, 60° and 90° for 30s each. The test device sits on a turntable that rotates with a speed of 5 times per minute. The sensor must not suffer any damaging effects from the high pressure water in appearance and function.
