P1PM Reflex Light Barrier Expands PNG//smart Portfolio

The wenglor sensoric group is expanding its PNG//smart portfolio in the field of optoelectronics with the P1PM reflex light barrier. The P1PM reflex light barriers work based on an innovative detection method that records back-scattered light intensity and distance. The sensors use red LED light to detect objects contactlessly, regardless of color, surface finish and shape. They are taught to any reference background via teach-in. Reliable detection of glossy, uneven and even semi-transparent objects is therefore achieved – without an additional reflector. 

The P1PM reflex light barriers, which are available in a total of four variants, are particularly impressive due to their versatile applications. Thanks to their combined detection principle, the reflex light barriers determine the intensity of the backscattered light as well as the distance of the light spot to a previously taught-in reference background. As a result, distances and surface finishes are reliably detected up to one meter, regardless of color, shape and surface finish. Detection without a reflector offers further advantages: The sensor can be mounted in places where there is no space for a reflector. Reflector-free installation also enables considerable time and cost savings. This avoids system downtimes due to dirty or defective reflectors. 

High Process Reliability in Different Working Environments
The P1PM reflex light barriers impress with two separate teach-in modes: They can be taught on both a static and a moving reference background. Parameterization via IO-Link allows both operating modes of the PNG//smart reflex light barriers to be set. This means that the sensor can be adapted easily and individually to the respective application. The reflex light barriers detect objects even if they are located directly in front of the sensor optics, as they work without a blind spot. The P1PM reflex light barriers easily master challenging circumstances such as a dirty background or strong vibrations. This is because the built-in dynamic readjustment also compensates for gradual changes in the background without the need for a new teach-in.
