IEC 61496-1 is the primary international standard governing the design, construction, and testing of electro-sensitive protective equipment (ESPE), such as light curtains and laser scanners, to ensure machinery safety. It defines safety types (Type 2 vs. Type 4), requires stringent environmental testing for reliability, and mandates that devices fail to a safe state. The official PDF for the current 2020 edition is available for purchase through the IEC Webstore or national standards bodies like ANSI and BSI.
