1 Photoelectrics Diffuse-reflective, Background Suppression Type PH8CNB... Miniature sensor range Range: mm Sensitivity adjustment by potentiometer Modulated, red light 65 nm Supply voltage: to VDC Output: ma, NPN or PNP preset Make and break switching function LED indication for output and power Protection: reverse polarity, short circuit and transients Cable and plug versions Excellent EMC performance Excelent colour matching Product Description The PH8CNB... is part of a family of inexpensive general purpose diffuse reflective sensors with backgrund suppression in industrial standard 8 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 flexible. The output type is NPN or PNP and the output switching function is NO and NC.

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 8 C water at 8 KPa (8 bar) and a flow rate of 6L/min. The nozzle is held 5 mm from the sensor at angles of,, 6 and 9 for s 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.
