Applications

Presence Check of Reusable Containers on Roller Conveyors with Retro-Reflex Sensors

In breweries, reusable containers (KEG) must be transported between different work steps such as washing, filling or palletizing on roller conveyors. To prevent jamming and allow the continuous flow of material, the containers must be recorded and counted at several locations. Retro-reflex sensors installed on the side of the roller conveyors reliably detect beverage containers despite reflective, matt, light or black surfaces.

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.
