The Omron F3SJ-A0815N20 Safety Light Curtain combines 20 mm hand detection with an 815 mm protective height for machine safeguarding applications requiring extended vertical coverage. Its sensing field contains 54 infrared beams positioned with a 15 mm beam gap to monitor entry through the guarded machine opening. Operating from a 24 VDC power supply, the light curtain uses an M12 8-pin connector for electrical connection with the surrounding safety control architecture. The 815 mm sensing height provides substantial vertical coverage while retaining the hand-level detection characteristics of this configuration. The F3SJ-A0815N20 belongs to the F3SJ Series and is categorized among industrial hand protection light curtains available through Omron machine safety equipment.
The Omron F3SJ-A0815N20 is a F3SJ Safety Light Curtain designed for use in machine guarding, access protection, and point-of-operation safety around conveyors, presses, and automated lines. It is usually evaluated together with related models such as Omron F3SJ-A0245P30 (Hand/arm protection, 25 mm beam gap, 10 beams, 245 mm protective height, M12 Connector 8-pin) when engineers are matching safety light curtains to application risk levels and space constraints. Reviewing application type, beam gap, number of beams, protective height, and connection method makes it easier to select the right curtain for finger protection, hand detection, or body protection zones along the machine. The F3SJ-A0815N20 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light.
