Photoelectric Sensors With Error-Free Alignment
Pepperl+Fuchs' RAL series photoelectric sensors feature a multiple-beam light grid and one-piece metal slot housing in widths from 50 mm to 150 mm, 5 kHz switching frequency, a one-shot timer, beam suppression and sensitivity adjustment, and can detect targets as small as 0.5 mm with response times as fast as =0.1 ms. The sensors require just one transistor with N/O or N/C PNP output. They are IP67-rated and carry the CE mark. A useful application is small parts detection and counting.
