Product Description
Ordering Key
The PA18C.T... is part of a
family of inexpensive general
purpose through-beam sensors in industrial standard 18
mm cylindrical ABS housing.
The sensors are useful in
applications where high-accuracy detection as well as
small size is required.

Sensitive adjustment
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.

Installation Hints
To avoid interference from inductive voltage / Relief of the cable strain
current peaks, separate the proximity switch
cables from any other power cables. E.g.
Engine, contactor or solenoid cables
