Light band sensors accurately detect objects’ front edge

Light band sensors
Wenglor’s new retro-reflex sensors can reliably detect objects with irregular or asymmetrical shapes, for example in the field of intra-logistics.

With three models for different light band heights, high levels of user-friendliness and special logistics functions, the light band sensors can prevent bottlenecks and jams in warehouse processes. The P1EL100 (27mm light band height), P1EL200 (42mm light band height) and P1EL300 (54mm light band height) have been developed as two-dimensional light barriers with a homogeneous laser light band. They recognize objects with various shapes or perforated surfaces, including dark, transparent or glossy objects, at a range of up to 1.6m. The devices can detect extremely small parts down to 4mm throughout the entire range of 0 to 1.6m thanks to the collimated, homogeneous laser light band with laser class 1. Smart functions integrated into the sensor allow the suppression of uneven conveyor belt areas through the use of dynamic teach-in and dynamic readjustment of the switching threshold. The sensors combine emitter and receiver in a single narrow housing only 27mm wide, which can be mounted to the side panels of conveyor systems in just a few easy steps. The sensor’s plug can be rotated up to 180° for flexible installation and matching mounting brackets, M4 through-bolts and press-fit sleeves, as well as reflector sets, simplify precision installation and alignment of the retro-reflex sensor.
