Omron F3SJ-B0785P25 Safety Light Curtain
The Omron F3SJ-B0785P25 Safety Light Curtain provides 25 mm hand detection across a 785 mm protective height for safeguarding access to hazardous machine areas. Its protective sensing field consists of 38 infrared beams arranged with a 20 mm beam gap, creating optical coverage across the guarded opening. The light curtain operates from a 24 VDC power supply and uses an infrared LED light source to establish the sensing field. Its 785 mm protective height provides extended vertical coverage while maintaining hand-level detection for machine safeguarding applications. The F3SJ-B0785P25 belongs to the F3SJ Series and forms part of the 25 mm hand protection light curtain range available within Omron machine safety products.
