SICK ’s new ELG automation light grid is intended for detection tasks for which a single beam sensor is insufficient. The sensor system consists of two profiles in which transmitters and receivers are integrated at intervals of 30mm or 60mm and the electrical evaluation unit accommodated.
With up to 128 optical elements, detection areas with a variety of sizes can be achieved. This would normally require the installation of numerous individual photoelectric switches.
Ranges of 0m-2m or 0m-12 m are available, with monitoring heights of 90mm-1,410mm or 450mm-3,300mm. In outdoor applications, equippers of door and gate systems or vehicle-separation solutions at toll booths, in particular, profit from the ELG's optimum size / performance relationship, its robust housing, its high enclosure rating, and its immunity to constant light of up to 150,000 lux.
Standard plugs or cable lengths of up to 15m solve all connection tasks. In material flow technology, on packaging machines, and in other indoor applications, the optical synchronization of transmitter and receiver modules and the typical industrial connection systems offer economical installation.
Wiring is considerably simplified, allowing easy integration in plant and control systems, and rapid commissioning. As the ELG is fully electrically compatible with standard photoelectric switches, it can also be rapidly and easily integrated as an upgrade.
