Presence and Congestion Check of Food Packaging in Dynamic Checkweighers Using Retro-Reflex Sensors

In the food industry, packaged goods must undergo quality control on dynamic checkweighers. The transport of these objects into or out of certain zones must be reliably monitored in order to prevent congestion. A retro-reflex sensor made of food-safe materials (FDA-compliant) is installed on the side of the conveyor belt. It detects transparent objects, is waterproof and resistant to cleaning agents (protection class IP69K). Thanks to the stainless steel 316L housing and captive optics, it is ideal for the food industry.

Retro-Reflex Sensors for Transparent Objects

In addition to detecting glossy, chrome-plated or reflective surfaces, retro-reflex sensors for transparent objects also detect and count transparent objects such as glass or film using red light. Objects are detected by interrupting the light beam between the sensor and the reflector.
