For a detection height < 700 mm, the dimension may vary.
The SLG-2 is an optical light grid. It consists of a sender and a receiver. The sender
consists of several sender elements (LEDs) and actuation electronics. The receiver
consists of receiver optics, several receiver elements (photodiodes) and control unit.
3.2.2 Measurement principle
Providing no object is located between the sender and receiver elements, the light
beams from the sender elements will hit the receiver elements. If an object is located
between the sender and receiver elements, the light beams will be blocked, depending
on the size of the object.
The detection area is determined by the detection height and the sensing range of the
light grid. The detection height is determined by the beam separation and the number
of beams. The sensing range of the light grid is the distance between sender and
receiver.

3.2.3 Detection height
The detection heights of the SLG-2 are between 100 mm and 2,400 mm:
•
100 mm increments between 100 mm and 800 mm.
•
200 mm increments between 800 mm and 2,400 mm.
3.2.4 Beam separation, minimum object size, minimum object width and minimum object length
The beam separation is the distance from the center of one LED to the center of the
nearest LED.
The beam separation is an important parameter for determining the resolution. To meet
different resolution requirements, the SLG-2 is available with different beam separation
variants.
