The Omron F3SG-4SRA1400-14 is a Type 4 safety light curtain from the F3SG-SR series, built for finger detection with a 14 mm detection capability. That 14 mm resolution means it catches fingers reaching into the hazard zone — finger-protection class per IEC 61496-1 — so it suits press brakes, assembly stations, and robotic cells where hand access must be blocked without stopping the machine cycle entirely. The 1400 mm protective height and 0.3 m to 10.0 m operating range cover a tall reach zone; you can mount the emitter and receiver up to 10 m apart, which fits large press beds or conveyor lines. The 10 mm beam pitch and 139 beams give dense coverage, so a hand or finger entering anywhere in the field triggers the safety output. Runs on 24 VDC, standard for safety circuits.
Blank and mute functions are built in — blanking lets you mask fixed obstructions (like a fixture post) within the field, and the muting function allows the curtain to be temporarily overridden during a material pass-through, which is common on conveyor infeed stations. These features are part of the standard firmware, not an add-on module.
