Robust IR Light Grids For Presence And Dimension Control

With a footprint of 40 mm x 20.5 mm, the sensors, which are designed to save space, should fit easily into different systems. The switching DGI variant can cover up to 2010 mm detection height and, depending on the variant, recognize objects with diameters from 0.9, 2, 4, 8 or 25 mm. With the response times between 0.8 and 4.8 ms, even small objects should be reliably recognized and counted at high speed. Contrinex names small parts and film production as well as packaging applications or the pharmaceutical industry as fields of application for the DGI variant.

Recognize position and dimensions at the same time

In addition to the presence of the object, the measuring MGI version should also recognize its dimensions and position. According to the manufacturer, the sensors can cover a measuring range height of up to 1438 mm, the resolution is 5 or 12 mm. The measured values ​​are output as an analog 0 to 10 V or 4 to 20 mA signal. Typical areas of application for measuring infrared sensors are logistics, automated packaging systems, storage rooms or the wood industry. (jv)
