Product Description
The PA18C.T... is part of a
family of inexpensive general
purpose through-beam sen-
sors 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 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 appea-
rance and function.
