Wireless laser sensors for short distances facilitate non-contact monitoring of all movements. This makes sense, for example, with large load carriers (LLC) which are so heavy that they would subject other sensors to an unacceptable level of wear and tear. Or for small load carriers (SLC) which are so light that they cannot be detected by mechanical sensors.
No wear and tear thanks to non-contact optical sensor technology
Simple mounting in conventional racks
Reliable even with low-contrast features and reflecting surfaces
Impervious to optical interference from industrial surroundings
Using non-contact monitoring, the wireless laser sensor automatically detects the occupancy of slots for containers or other load carriers. This information is passed on to the control system. Permanent monitoring means that a material requirement request is immediately triggered when the minimum stock level is reached.
Distance is measured by logging the transit time of a light impulse ("optical time of flight"). This measuring principle has the huge advantage that the switching point of the sensor is only minimally dependent on the object material and colour. Even adverse ambient conditions like dust or dirt have hardly any impact on the resulting measurement. The detection range can be configured for a distance of 50 mm up to 500 mm.
A long-life battery guarantees maintenance-free operation and long run times. In an eKanban application, the battery lasts for several years.
