Product Description
The PA18C.P is part of a fam-
ily of inexpensive general pur-
pose retro-reflective sensors
in industrial standard 18 mm
cylindrical ABS housing.
The sensors are useful in
applications where high-ac-
curacy 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 sensitivi-
ty 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 clea-
ning. 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.
