Detects Presence of Transparent Films

Case Number 1

last update: November 4, 2009

This application uses a Retroreflective Photoelectric Sensor for clear films.


Install a Sensor and a Reflector between which a clear film is placed. This Sensor enables stable detection of clear films with optical and circuit technology that detects slight signal differences caused by clear films.

Know-How

Conventional retroreflective sensors did not provide stable detection of clear films with minute light attenuation.

Benefit / Efficiency

Our optimized optical and circuit technology enables stable detection of clear films.
