ABOUT LIGHT GRID SENSORS

Light grid photoelectric sensors are a small, non-safety version of Sick's famous light curtains.

WLG LIGHT GRID SENSOR
The WLG light grids function according to the reflection principle. A suitable reflector, mounted directly across from the sensor's exit window, reflects the emitted light back to the receiver of the sensor. This produces a two dimensional plane between the sensor and reflector. When the detection plane is broken, the sensor produces an output.
The WLG light grid sensor is specifically designed for use in parts ejection applications or any processes where product-positioning variations occur. They can also be used to detect objects, determine the height or length of objects or detect irregularly shaped objects.

MLG LIGHT GRID SENSOR
The MLG light grid is designed to meet a variety of application requirements. It offers a host of possibilities with regard to size, resolution, configuration and interfaces. The electronics are completely integrated into the compact housing. Height measurement, zone division and monitoring, object recognition, hole and crack detection, slack control and blanking control are all tasks suitable for the MLG. In addition, the multiple scan function makes it possible to detect large and small objects.

High modularity and integrated standard measuring function are distinctive features of the MLG. The following features are available:
- various beam spacing of 10, 20,30 or 50 mm
- detection heights between 100 mm and 3140 mm
- light grid separation of 0 to 5 m or 0 to 8.5 m
- two different mounting styles

Discrete inputs, outputs and serial data offer a wide rangeof interface combinations. Important parameters, such as the size of objects to be detected can be defined using the user-friendly software, MLG Setup. The MLG Setup application assistant helps setup the most common applications.
