What this light curtain is for
The Omron F3SG-4RE0640P14 is an economy safety light curtain from the F3SG-4RE series, designed for point-of-operation guarding on machinery where a compact, cost-effective solution is needed. As a safety light curtain, it creates an invisible infrared barrier that, when broken, sends a stop signal to the machine control system — a standard approach for safeguarding presses, assembly stations, and packaging lines per IEC 61496-1.
What the order code tells you
The order code F3SG-4RE0640P14 encodes the key selection parameters: the '0640' segment indicates a 640 mm protective height, and the 'P14' suffix points to a 14 mm resolution — finger-detection class per IEC 61496-2. A 14 mm resolution means the curtain detects fingers reaching into the hazard zone, making it suitable for applications where hand access must be prevented but larger body parts are not the primary risk.
