APC-18P

**APC-18 Air Purge Collar for 18 mm Sensors** 

## **Datasheet** 

_For Use with 18 mm Threaded-Barrel Sensors_ 

- Positive air pressure prevents water, dust, and other airborne contaminants from collecting on the sensor face 

- Air flow helps cool sensors affected by ambient heat in the sensing environment 

- Works with many of Banner Engineering's 18 mm threaded-barrel photoelectric and temperature sensors 

**Note:** Air temperature affects the speed of sound. The APC-18 Air Purge Collar should not be used with ultrasonic sensors.

1. The internal and external threads of the Air Purge Collar provide two mounting options for 18 mm threaded-barrel sensors: 

   - Thread the collar all the way onto the sensor, then mount the collar in the mounting bracket by its external threads, or 

- Install the sensor in the mounting bracket, then thread the collar all the way onto the sensor 

- 2. Attach the air supply to the collar by pushing a 1/8-in ID air hose onto the air connection. 

**Note:** To prevent contamination on the sensor face, use clean, dry, instrument-quality air. 

**Note:** For best sensing results, teach the sensor while air is flowing.
