Optical wireless sensors mean that movements can be monitored without any contact whatsoever. This is particularly beneficial in conjunction with large load carriers (LLC) which are very heavy and would subject other sensors to excessive wear and tear, or tiny SLC which are too light to be detected by mechanical sensors.
Via optical reflections, the light sensors automatically detect the application status in question, for example that of load carriers inside a rack. Here the range of detection above the wireless sensor is up to 40 mm for conventional colours. If the sensor detects a change in the quantity of materials, it automatically notifies the control system, triggering a fully automated request for replenishment.
Since detection is non-contact, neither the detected object nor the sensor is subject to wear and tear. In combination with a long-life battery, both maintenance-free operation and long running times are guaranteed. The service life of the battery in an eKanban application, for example, is several years.
