Sensor Fotoelétrico, sensor Slot, Sensor Fotoelétrico Slot, Pepperl-Fuchs, GL30-RT/32/40a/98a, Pepperl-Fuchs GL30-RT/32/40a/98a, Sensor Fotoelétrico Slot Pepperl-Fuchs GL30-RT/32/40a/98a

A linha fotoelétrica da Pepperl+Fuchs também abrange sensores slot especiais. Esse tipo de sensor é usado apenas quando uma curta distância de detecção é necessária. Eles oferecem a vantagem de ter uma instalação elétrica mais simples em comparação aos sensores tipo barreira, uma vez que a fiação é necessária somente para um dispositivo. Além disso, não há problemas de alinhamento entre o emissor e o receptor.

Product information

Photoelectric slot sensors offer vast installation benefits thanks to their housing design. When it comes to operation, these new generation devices boast features such as high resolution, high repeatability, automatic signal threshold adjustment, ambient light resistance, and detection of and/or light transmission through transparent objects. Cross-talk protection enables parallel installation of devices despite extremely high switching frequency. These characteristics guarantee reliable detection of small parts, from 0.3 mm, across the entire detection range, even in very fast moving applications.

Operating principle

Photoelectric slot sensors are photoelectric sensors that operate according to the thru-beam sensor principle. The transmitter sends signals directly to the receiver. If an object breaks the light beam, the switching element function is triggered. The special U-shaped design means the transmitter and receiver can be accommodated in one housing, which ensures high resistance to vibrations. In contrast to standard thru-beam sensors, photoelectric slot sensors have the added advantage of not requiring complex electrical installation, as only one device needs to be connected. Also, adjustment of the optical axes is not necessary.
