Type 4 light curtains from the EXTENDED SLIM range are TÜV, CE and UL certified according to IEC 61496-1/2, IEC 61508-1/2/3 and ISO 13849-1. Protective heights range from 170 to 1,610 mm with integrated EDM*, restart interlock and beam coding. Since EDM includes a relay monitoring function, users can also avoid the cost of wired relays. The slim housing (26 × 26 mm) enables blind-zone free installation and connection is via an integral 5-pin or 8-pin M12 pigtail. This range of light curtains is configured and monitored wirelessly via a Bluetooth® signal and free smartphone app – a world first!
