O5D Series photoelectric sensor integrates time-of-flight sensing principle with PMD technology for long diffuse-background suppression sensing ranges of up to 2 m. The switch point, visible on the sensor's numeric display, is set by pushbuttons. The O5D100 model displays range in centimeters, and the O5D101 model displays range in inches. The Class 2 laser has a visible red light spot for trouble-free installation, and has a complementary LO/DO, PNP output.
