SE4B Light Curtains Type 4 (07/06/21) SE4B Series Light Curtains Ensures the Safety of Working Environment • Type 4 light curtains conforming to safety category 4 • Hand-type light curtain detects objects as small as ş30 mm. • 11 detection ranges: 147 to 1,617 mm Type 4 Light Curtains Light curtains are installed as safeguarding measures for personnel where: • A safety guard cannot be installed due to structural reasons • A safety guard is opened/closed frequently • Safety guards are not necessary, but the hazard must be stopped when a person enters the area. The SE4B Light curtains are electro-sensitive protective equipment com- plying with EN 61496-1/-2 and safety category (ISO 13849-1). Complying with safety standards: EN 61496-1, prEN 61496-2, UL 61496-1, UL 61496-2, UL 508, CSA 22.2 No. 14, CSA 22.2 No. 0.8 (07/06/21) 2 • External device monitor is installed within the light curtain (see page 9).
