This is the Omron F3SJ - E1025P25 safety light curtain designed for hand detection of opaque objects. It features a detection capacity of φ25mm, achieved through 50 optical axes with a 20mm pitch, providing a detection width of 1025mm. The detecting distance ranges from 0.2m to 7m. The response time is ≤15ms (ON→OFF) and ≤70ms (OFF→ON), with a 2s start - up time after power - on. Powered by SELV/PELV DC24V±20% (ripple p - p ≤10%), it consumes ≤63mA (emitter) and ≤51mA (receiver). It provides 2 PNP transistor OSSD outputs (load current ≤200mA) with output load short - circuit protection and reverse - connection protection. With an IP65 protection structure, it operates in an ambient temperature of - 10℃ to 55℃ (no freezing). Safety features include mutual - interference prevention (3 - set algorithm), self - test, and external test. The 3m cable (5 - core emitter/6 - core receiver) allows 30m extension. The 2kg aluminum - cased unit includes PMMA optics, ensuring reliable performance for industrial safety - related detection tasks.
