A sensor most suitable for sensitive materials that does not use ultraviolet or infrared as the light source
Easy detection setup eases the burden on the users
The Photohead PH22 is a sensor designed to detect a transparent web or a nonwoven fabric as a detector for EPC. The sensor adopts SPD as the detector element and white LED as the light source to offer a long time, safe operation of meandering detection.
- Detects even a slight displacement of web by emitting light with uniform intensity.
- Use of SPD enables faster reaction and improves the detection accuracy for high-speed operations.
- Detects a 0.1mm displacement of transparent web.
- Use of white LED for the light source enables a long time, stable operation and helps to reduce cost.
