The Omron F3SG-4SRA0560-45 is a type-4 safety light curtain from the F3SG-SR series, rated for Arm/Foot protection with a 45mm detection capability. It covers a 560mm protective height using 14 beams spaced at 40mm pitch, with an operating range from 0.3m out to 20.0m.
The 45mm detection capability means this curtain catches a hand or forearm, not just a fingertip — it's sized for point-of-operation guarding where a 14mm curtain would be overkill and a 30mm might miss a wrist. The 40mm beam pitch and 14 beams give you that 560mm protected zone; if your opening is taller, you stack multiple units. The 0.3m minimum range lets you mount it close to the hazard, and the 20m max covers long conveyor or gantry approaches without a second set of optics. Runs on 24VDC, which is standard for safety circuits — no special power supply needed. The IP65/IP67/IP67G rating means it's dust-tight and handles hose-down washdown; the 'G' suffix indicates oil resistance, so it lives on a machining center or press line without fogging up. Operating temperature from -30°C to 55°C covers unheated warehouses and foundry floors alike.
Integration notes
Blanking and muting functions are built in — blanking lets you block out fixed obstructions (brackets, chutes) from the detection field without faulting the curtain, and muting suspends the safety output during a defined material pass-through. Both are configured via the controller, not hard-wired. The 24VDC supply powers both emitter and receiver; check the total current draw against your safety relay or controller's output capacity.
