Photoelectric sensor principles and light sources

The optimum solution in a photoelectric sensor application calls for selecting the best-matching sensing principle and the appropriate light source. Each sensor principle and light source provides specific benefits.

Properties of the 4 available light sources:
Standard LED: Diffuse light spot for robust position-tolerant object detection, for example in parts feeding
Baumer PinPoint LED: Small, homogeneous light spot with sharp edges for high-precision position feedback
Infrared LED: Invisible light beam e.g. for light barriers in the public area
Laser: Highly focused, easily visible light beam for positioning tasks in the micrometer range

7 sensor principles for optical object recognition:
