## **Product Descri tion p**
## **Orderin Ke g y**
The PH18CNT... is part of a family of inexpensive general purpose through-beam sensors in industrial standard 18 mm cylindrical and square ABS housing.
Compact housing and high power LED for excellent performance-size ratio.
Compact housing and high **Type** power LED for excellent **Housing style square** performance-size ratio. **Housing size** The potentiometer used for **Housing material** adjustment of the sensitivi- **Housing type neutral** ty makes the sensors highly **Detection principle** flexible. The output type is **Sensing distance** NPN or PNP and the output **Output type** switching function is NO and **Output configuration** NC. **Connection type Sensitive adjustment**
The sensors are useful in applications where high-accuracy detection as well as small size is required.

* 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.
