Stacker Crane Positioning

In the ASRS (automated storage retrieval system), the stacker crane needs to be precisely positioned in order to avoid product or parcel damage and ensure accurate loading/unloading positioning. A solution that can precisely direct the location of the storage area so that equipment and product damage can be eliminated is needed.


Banner’s time-of-flight LT7 laser sensors provide long-distance ranges up to 250 m with a visible red laser spot for easy alignment.

Depending on range needed, a diffuse or retroreflective time-of-flight laser sensor can be used. Retroreflective LT7 laser sensors provide ranges up to 250 m and diffuse LT7 laser sensors provide long-range background suppression up to 10 m.

The LT7 laser sensor features TEACH-mode programming, using integrated push buttons or a serial interface. The time-of-flight LT7 laser sensor provides two alarm outputs with ongoing LCD display continually showing sensing distance in millimeters or hundredths of an inch for easy troubleshooting.
