Our 16 mm web position sensor provides accurate and precise detection of the web edge of any material without the need for calibration. It’s applications include edge detection for edge guiding and center guiding when the web width does not vary significantly. The sensor can be used with an ARIS WGS web guiding system or as a stand alone sensor to monitor web edge position or presence/absence along with an ARIS SCU (sensor control unit).


Reliable web guiding across all types of materials in a small sensing window

The small sensing window is ideal for edge detection applications with very little web width variation or web material position variation
