SICK PSD01-1501 Through-Beam Photoelectric Sensor

SICK PSD01-1501 is a two-beam through-beam safety light-beam sensor in the M4000 Standard A/P family. This passive unit functions as part of a safety barrier, pairing with a separate emitter to detect beam interruption across a 500 mm spacing. The PSD01-1501 designation denotes a two-beam arrangement configured for industrial guarding across machine doors, conveyors, and perimeter guards in automation environments. As part of SICK’s M4000 platform, it is designed to integrate into safety circuits and guard-monitoring setups, delivering reliable detection when a beam is blocked and helping satisfy safety-system requirements in heavy industry settings.
