The ELG is available with up to a 3300mm detection height, and is used for leading edge detection of luggage, counting boxes, and (in Cross Beam mode) detection of smaller parts.
The HLG is designed for high-resolution and high-speed detection of the smallest objects, like letters in a mail system. It is often used to reliably measure the length of a conveyed object, in conjunction with an encoder.
This high-resolution light grid is available with 2 analog outputs or 3 discrete outputs, and with sensing heights up to 3.2 m. It is simply configured and installed. Popular for height and progrusion measurement, package orientation, and bottle detection.
