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 specifically addresses applications where the presence of a person within a defined dangerous zone must be detected to initiate a safety function—typically stopping the machine before injury occurs.

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.

Legally, that depends on your local regulations. In the EU and UK, under the "Work Equipment Directive" (2009/104/EC), existing machinery must be upgraded to current safety standards if a risk assessment shows a significant hazard. Practically, most safety auditors will expect compliance with the 2018 edition by 2023 at the latest.
