The Omron F3SG-4SRB0240-25 is an active-production safety light curtain from the F3SG-SR series, rated for hand protection with a 25 mm detection capability. Its 20 mm beam pitch and 12 beams cover a 240 mm protective height, with an operating range from 0.3 m to 20.0 m.
The 25 mm detection capability and hand-protection rating mean this curtain is sized for finger and hand detection at the access point — not for body presence or area guarding. The 240 mm protective height and 20 mm beam pitch define the field; verify the hazard zone fits within that vertical span and the 0.3 m minimum range. Supply is 24 VDC, standard for safety circuits. Ingress protection is IP65/IP67/IP67G — dust-tight, waterproof, and oil-resistant with the G suffix for environments where cutting fluids or washdown are routine. Blanking and muting functions are built in, so the curtain can ignore fixed obstructions (blanking) or be temporarily overridden during a material pass (muting) without external logic modules.
