Omron F3SG-4RE is the Type 4 Easy safety light curtain of the F3SG-R series, offering fast response and simple wiring for plain ON/OFF applications. There are 14 mm finger protection models with 10 mm beam gap and 30 mm hand/arm protection models with 20 mm beam gap. The output type is fixed by the model code: P models have PNP outputs, N models NPN outputs. A prewired 0.3 m cable ends in a 4-pin M12 connector, and XS5 series cables are used for extension. With a notice dated 8 July 2026, the manufacturer is discontinuing the series.
Per the datasheet, F3SG-4RE is a Type 4 device to IEC 61496-1 and reaches PL e, Category 4 to EN ISO 13849-1. Response time is 5 to 15 ms ON to OFF and 25 to 75 ms OFF to ON. Range is 0.3 to 10 m (14 mm) or 0.3 to 20 m (30 mm); short mode is set via the range select input. The two safety outputs carry up to 300 mA. Protection is IP65 and IP67, operating temperature -10 to 55 °C. Final order entry is 18 December 2026, last shipping 19 January 2027; replacement: F3SG-SR.
