Fill Level Monitoring When Unwinding Labels with Retro-Reflex Sensors

When automatically rolling out and applying labels, it is important to ensure that there is enough material on the roller and that there is no interruption in the process. The retro-reflex sensor serves as an early warning system to permanently check the material supply of label or film unwinders and thus prevent idle running. If there is too little material on the roller, it detects the reflector installed opposite it and switches. This allows the operator to replace the roller in good time. The required roller thickness can be individually adjusted thanks to the visible light spot.

Universal Retro-Reflex Sensors

Universal retro-reflex sensors are suitable for the detection of glossy, chrome-plated or reflective surfaces thanks to the polarization filter. They work with red light or laser light. Objects are detected by interrupting the light beam between the sensor and the reflector.
