Omron F3SJ-A0245P20 Safety Light Curtain
The Omron F3SJ-A0245P20 Safety Light Curtain is a machine safeguarding sensor designed for hand protection with 20 mm detection capability. Its 16 infrared beams are arranged with a 15 mm beam gap to create a 245 mm protective height for monitoring entry through a guarded machine opening. The unit operates from 24 VDC and uses an M12 8-pin connector for electrical integration with the associated machine safety system. Its compact protective field is suited to access points where hand-level intrusion needs to be detected before personnel reach the hazardous area. The F3SJ-A0245P20 belongs to the F3SJ Series and forms part of the 20 mm hand protection light curtain range available within Omron machine safety products.

The Omron F3SJ-A0245P20 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-A1770N55 (Leg/body protection, 50 mm beam gap, 36 beams, 1770 mm protective height, M12 Connector 8-pin), and Omron F3SJ-E0465N25 (Hand protection, 20 mm beam gap, 22 beams, 465 mm protective height) 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-A0245P20 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required.
