The sensors are useful in applications where highaccuracy 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. - **Excellent EMC performance** ## C€ @.: EC@LAB **Orderin Ke g y PA18CAD10PAM1SA Type Housing style Housing size Housing material Housing type axial Detection principle Sensing distance Output type Output configuration Connection type Sensitive adjustment** ~~=|~~ ## **T e Selection yp** **Housing style Range Connection Ordering no.

* 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. **==> picture [62 x 80] intentionally omitted <==** **----- Start of picture text -----**
