Light band

In contrast to conventional photoelectric sensors with a dot-shaped light spot, a sensor that uses a light band can monitor a much larger area. The light band is generated by combining a PinPoint LED with special optics. The result is a consistent light band between the photoelectric sensor and reflector. This enables reliable, position-independent detection of objects that pass through the light band with varying positions or heights.
