The F3SG-4SRA0200-25-F is a Type 4 safety light curtain from Omron's F3SG-SR series, designed for hand protection with a 25 mm detection capability per the datasheet. That 25 mm figure is the minimum object size the curtain reliably detects — smaller than that, and the system may not see it. For hand protection per IEC 61496, this is the standard threshold: anything below 30 mm is finger/hand detection class. The 20 mm beam pitch and 10 beams give a 200 mm protective height, meaning the curtain covers a 200 mm vertical zone. The 0.3 m to 20.0 m operating range covers most machine access openings; the 0.3 m minimum dead zone means you can mount it close to the hazard without blind spots. Supply is 24 VDC, standard for industrial safety systems. The IP65/IP67/IP67G rating means the housing and optics withstand washdown — the 'G' suffix indicates oil resistance, suitable for machining centers or food processing lines where coolants or cleaning agents are present.
Integration notes
The blanking and muting functions are built into the curtain's controller logic — no external module needed for fixed or floating blanking, or for muting sensors on a conveyor infeed. Verify the controller model supports these features; the F3SG-4SRA0200-25-F emitter/receiver pair is compatible with Omron's F3SG-SR controller series. The 24 VDC supply powers both the emitter and receiver; total current draw per the system manual is typically under 200 mA per unit, but confirm with the controller's power budget.
