Product information
Photoelectric slot sensors offer vast installa-
tion benefits thanks to their housing design.
When it comes to operation, these new gen-
eration devices boast features such as high
resolution, high repeatability, automatic sig-
nal threshold adjustment, ambient light resis-
tance, and detection of and/or light
transmission through transparent objects.
Cross-talk protection enables parallel instal-
lation 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.
