Sensor solutions for side-tracking shelves
Side-tracking shelfs allow storage space to be used economically and efficiently. It must be possible to access the goods in single racks quickly and safely when needed.
Our sensors ensure precise positioning and synchronization of shelves and drives. Single and multiple light beam safety sensors also safeguard the foot space in the shelf rows and access to the shelf aisles.
While the side-tracking shelf is moving, the foot space is to be monitored for the presence of persons. If multiple shelf rows are installed one behind the other, there must be no interference between the sensor signals of the rows.
The SLS 46C single light beam safety devices monitor the foot space over a length of up to 70 m. They are available as a type 4 variant and as a particularly easy‑to‑align type 2 variant. The use of models with red light and infrared light prevents mutual interference between the shelf rows.
When closing the aisle between two shelves, the shelves should be prevented from moving up. To do this, you need to determine the distance between the shelves. Two distances should be called up via switching outputs.
The HT46C series universal diffuse sensors use red or infrared light and work reliably even with dark and glossy objects. The devices have two switching outputs, each of which can be precisely taught to a distance.
If a vehicle is in the aisle or the aisle is closed, access to this aisle should be secured.
The multiple light beam safety devices of the MLD 500 series are used for access guarding. For operating ranges up to 8 m, particularly cost-effective transceiver systems are available that require an electrical connection on only one side. Alternatively, transmitter-receiver systems offer operating ranges of up to 70 m.
