These cubic photoelectic switches are of the diffuse sensor type and use background suppression to improve detection for difficult targets such as small, fast-moving parts on conveyors/automated machinery or targets against light backgrounds. * Polarity PNP * Output light-ON * Terminated by 2m cable * Eliminates false triggering * Excellent suppression of light-colored backgrounds * Insensitive to the target size, colour, shape or surface finish * Stable, accurate detection
