SICK Sender/Receiver ELG3 Series

Two-dimensional inspection or counting tasks are important in automation. SICK’s automation light grids can be used in a number of these solutions, such as detecting and counting irregularly shaped objects, people and vehicles, and checking for presence and pallet overhang detection. The tasks are so versatile that one light grid cannot fulfil the requirements of every application. Light grids from SICK offer multiple ranges, heights, sizes, orientations, and resolutions which simplify integration through high flexibility and performance.

SICK offers the versatile ELG, an extremely tough switching automation light grid with different monitoring heights and beam separations. The ELG is not sensitive to glare caused by sunlight and flashing light. The ELG is available with up to 128 beams and with a minimum beam resolution of 10 mm.

Up to 128 beams
Different beam resolutions 10 mm, 30 mm and 60 mm
High operating reserve for scanning ranges up to 12 m
Potentiometer for sensitivity adjustment
Ambient light immunity up to 150,000 lux
Tough aluminium housing
PNP/NPN, relay output and a test input
Optical synchronization

High immunity to ambient light when exposed to sunlight and reflective objects, eliminating false trips
A high operating reserve increases application availability and reduces maintenance costs
Efficient and effective way to evaluate multiple beams in one housing with one connection cable
Simple commissioning thanks to a larger optical aperture angle and manual fine adjustment option
Optical synchronization enables quick installation and cost effective connection
The sensitivity adjustment enables trouble-free operation without reflection problems for the customer

Typical applications are in logistics for checking for projections on pallets and counting boxes and small parts. In addition, the ELG is used for vehicle separation at tollbooths.
