Extremely versatile photoelectric sensors for object detection:
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
