detect high-speed objects in motion.
The frame light barriers from XECRO are very fast, high resolution, fully integrated light curtains which can operate in two modes:
In the static mode the output is active as long as an object is in the field of light. The static mode can be used to capture objects which permanently move uncontrolled through the field of light. E.g. such as during the extrusion of plastics or other materials.
In the dynamic mode an impulse with an adjustable length is generated as soon as a fast moving object passes through the field of light. The advantage of this mode is that it is possible to a certain degree to compensate for dirt on optical elements and yet still keep the very high resolution.
