Photoelectric sensor with laser light for reliable triggering

Description

In a recycling system, retro-reflective photoelectric sensors are to be used for triggering. Important for this application is that the error angle of the optics be as small and as constant as possible. Otherwise, it is possible that light may not be incident on the reflector.

Solution

PRKL 3B laser retro-reflective photoelectric sensors with polarization filter are used. Laser protection class 1 allows the user to convert to these devices without considerable effort with respect to protective measures and documentation. The user also benefits from this sensor solution's attractive price/performance ratio.
