Based on continuous, homogenous light band, Wenglor’s new retro-reflex sensors can also reliably detect objects with irregular or asymmetrical shapes, for example in the field of intralogistics. With three models for different light band heights, high levels of user friendliness and special logistics functions, wenglor provides an economically efficient and easy to use solution such as for the prevention of bottlenecks and jams in warehouse processes. This results in improved productivity, increased system availability, more flexible production and reduced costs. Retro-reflex sensors with light band P1EL 100 (27 mm light band height), P1EL200 (42 mm) and P1EL300 (54 mm light band height) have been developed as two-dimentional light barriers with homogenous laser light band. They recognise objects with various shapes or perforated surfaces – even dark, transparent or glossy objects are accurately detected – at a range of up to 1.6 m. All the Wenglor models can detect extremely small parts down to 4 mm throughout the entire range of 0 to 1.6 m. Beyond this, smart functions integrated into the sensor such as suppression of uneven conveyor belt areas through the use of dynamic teach-in and dynamic readjustment of the switching threshold, as well as the very narrow housing with a width of just 27 mm, offer tremendous application and installation advantages. Quick and easy initial start-up with teach-in key The sensors can be taught-in quickly and in an uncomplicated manner by simply pressing a key. In order to avoid inadvertent contact with the key and to permit flush mounting, the key is located at a slightly recessed area on the housing. External teach-in is also possible via the controller using a 24 V signal. The dynamic teach-in function is also highly advantageous for use on conveyor belts where uneven belt areas can easily be suppressed. Even small parts as little as 4 mm can be reliably detected in the additional precision teach-in mode. Diverse mounting equipment for any system The sensors combine emitter and receiver in a single narrow housing with a width of just 27 mm, which can be mounted to the side panels of conveyor systems in just a few 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 sensors.
