wenglor sensoric - Michael & Maik explain the Benefits of Teach-Free Retro-Reflex Sensors

The retro-reflex sensor for transparent objects with teach-free technology sets a new milestone. The special advantage: It works immediately after installation and does not need to be taught in manually during initial start-up. The sensitivity adjusts automatically during operation. This eliminates the need for time-consuming and error-prone manual teaching of individual sensors.
