A light curtain detects a finger crossing a plane. IEC 62046 requires systems that detect a lying on the floor—someone already inside the danger zone who never triggered an entry sensor.
IEC 62046:2018 provides critical requirements for the selection, positioning, and commissioning of presence-sensing protective equipment (ESPE), such as light curtains and laser scanners, to enhance industrial machinery safety. This standard focuses on application-level risk reduction, including safety distance calculations, muting, and blanking, while supporting requirements for operator safety.
