Omron F3SG-4SRA is the Type 4 Advanced safety light curtain of the F3SG-SR series; the models on this page are the 14 mm finger protection versions. The series covers finger to body protection with 14, 25, 45 and 85 mm resolutions, and flexible height (-F) models provide protective heights in 40 mm increments up to 1 m. With IP67 and IP67G protection it withstands various environments. Monitoring and setting via IO-Link, USB and Bluetooth are possible with the F39-SGIT-IL3 Intelligent Tap.
According to the datasheet, F3SG-SR is a Type 4 device to IEC 61496-1 and reaches PL e, Category 4 to EN ISO 13849-1. For 14 mm models the operating range is 0.3 to 10 m in long mode and 0.3 to 3 m in short mode. The two safety outputs are selected as PNP or NPN by wiring and carry up to 300 mA load current. Functions include interlock, EDM, pre-reset, PSDI, fixed and floating blanking, reduced resolution, muting and warning zone. Up to 3 segments and 255 beams can be cascaded. The operating temperature is -30 to 55 °C.
