Omron F3SG-4SRB0480-25 Light Curtain, Hand Protection, 480mm

The Omron F3SG-4SRB0480-25 is a Type 4 safety light curtain from the F3SG-SR series, rated for hand protection with a 25 mm detection capability and a 20 mm beam pitch. That 25 mm figure is the smallest object the curtain reliably catches — anything smaller passes through, so it governs what body part is protected. With 24 beams across a 480 mm protective height, the curtain covers a zone just under half a metre tall; the 0.3 m to 20.0 m operating range means it works on short reach-in stations as well as long access paths up to 20 metres. The IP65/IP67/IP67G ingress rating handles hose-down washdown and temporary immersion, plus oil resistance — relevant for machining centres or food lines where coolant or cleaning agents are present.
