Wenglor P1EL100, P1EL200 and P1EL300 retroreflective sensors

Wenglor has released retroreflective sensors with a 27 mm light-band height (P1EL100), a 42 mm light-band height (P1EL200) and 54 mm light-band height (P1EL300). Developed to be two-dimensional light barriers with a homogenous laser light band, they recognise objects with various shapes or perforated surfaces — including dark, transparent or glossy objects — at a range of up to 1.6 m.

They can detect small parts down to 4 mm throughout the entire range of 0–1.6 m due to the use of the collimated, homogenous laser light band. Smart functions integrated into the sensor — such as the suppression of uneven conveyor belt areas through the use of dynamic teach-in and dynamic readjustment of the switching threshold — offer easy application and installation.

In order to avoid inadvertent contact with the teach-in 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 sensors combine emitter and receiver in a single narrow housing with a width of 27 mm, which can be mounted to the side panels of conveyor systems in a few steps. The sensor’s plug can be rotated up to 180° for flexible installation; matching mounting brackets, M4 through-bolts and press-fit sleeves, as well as reflector sets, simplify precision installation and alignment.
