Storage shelves are an important component of modern logistics warehousing systems, which can effectively utilize warehouse space and improve storage efficiency. The application of various sensors makes the shelves more intelligent, providing guarantee for the effective operation of intelligent warehousing systems. Following are the main application examples of  G-TEK  sensors on shelves.

1.Shelf occupancy detection
By installing the through-beam PF21T (or mirror reflective PF21R) at the entrance of the shelf, if the goods are misaligned, they will block the beam and trigger the photoelectric output response. Install a through-beam PF21T (or mirror reflective PF21R) inside the shelf to detect the presence of goods. If the goods are present, the beam of light is obstructed, triggering the photoelectric output response. 

2. Monitoring of protruding goods on shelves
Goods stored on shelves may protrude from the shelves due to abnormal conditions. The prominent goods thus become obstacles to the vertical movement of the stacker truck, which may cause damage to the shelves or stacker truck. Long distance through beam type photoelectric sensor or LND series LiDAR can be used to detect the position and status of shelves and goods in real-time, as well as detect whether any items have fallen, ensuring a safe operating environment.
