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. **==> picture [62 x 80] intentionally omitted <==** **----- Start of picture text -----**<br> 90°<br>60°<br>30°<br>0°<br>**----- End of picture text -----**<br> ## **Wiring Diagrams** **==> picture [415 x 212] intentionally omitted <==** **----- Start of picture text -----**<br> Receiver<br>NPN PNP<br>1 BN + V 1 BN + V<br>4 BK<br>(><br>2 WH<br>2 WH<br>4 BK<br>3 BU > 3 BU<br>V GND V GND<br>Emitter<br>1 BN + V<br>3 BU<br>o l<br>V GND<br>**----- End of picture text -----**<br> **2** Specifications are subject to change without notice (01.04.2011) **PA18C.T...** ## **O eration Dia ram p g** tv = Power ON delay ON Power supply OFF Present Target (emitter) Not Present Present Object Not Present ON Tv Break Output (N.C.)
