The IPS 400i is the smallest camera-based sensor for the compartment fine positioning of a high-bay storage device with double-depth shelves. Thanks to its high-performance, ambient-light-independent IR-LED illumination, fault-free use is possible for a working range of up to 2,400 mm. The also available heated version can be used at ambient temperatures as low as -30 °C. Its dimensions are unrivalled with respect to the small size. As a result, installation in constrained spaces poses no problem. Other highlights include the direct configuration on the device using printed configuration codes, which can be read in directly, the simple operation, four alignment LEDs and the information about the function reserve, which is output as a quality score.
