Laser Light Array
Balluff BLA0007 Light Array with IO-Link measures up to six objects in 16mm light field.
Balluff introduced its BLA0007 laser light array that can measure the size of up to six objects in its 16mm light field. Those measurements include object diameter and position; gap width and position; and edge position. The light array also offers modes such as counting and nominal/actual comparisons, which can be used simultaneously. If needed, it can be programmed to blank an area, so objects in that part of the array don’t trigger the sensor. Additionally, they can measure object height or gap dimensions, monitor hole placement or size, and detect the web edge of material like paper or cloth, including many transparent materials that are optically demanding. They can detect cable, wire, or threads as small as 0.3 mm.
