What it is and what it does
The Omron F3SG-4SRA0800-14 is an active-production safety light curtain from the F3SG-SR series, built for finger detection at 14 mm resolution — that's the gap a hand reaches past before the curtain trips, meeting IEC 61496-1 finger-protection class. Protective height is 800 mm, covered by 79 beams at a 10 mm pitch, giving a sensing range from 0.3 m out to 10.0 m. That range covers most machine-access zones on a production line — press brakes, assembly stations, robotic cells. Runs on 24 VDC, rated for -30°C to 55°C ambient, so it works in cold storage or a hot foundry floor without derating.
Where it fits — enclosure and washdown reality
IP65/IP67/IP67G means the housing and optics survive hose-down cleaning and oil mist — the IP67G suffix adds oil-resistance, which matters on a machining line where coolant spray is constant. No secondary cover needed for food-and-bev washdown cycles. The 800 mm protective height aligns with standard machine-frame openings; the bulk packaging (single-unit) is typical for a specified BOM line, not a multi-unit kit.
Built-in logic — blanking and muting
Onboard blanking lets you ignore fixed obstructions (a bracket or workpiece carrier) within the field; muting function allows the curtain to be overridden during a material pass cycle, as long as the muting sensors confirm the object is not a person. Both are standard in the F3SG-SR series, no external controller needed for basic setups.
Sourcing and lifecycle
Sourced to order against an RFQ; supply posture is standard factory-channel, not surplus or broker. No direct pin-compatible alternative exists within the same series at this protective height and resolution — the 14 mm finger detection and 800 mm height define the fit.
