The Omron F3SJ-A2020P25-TS is a type-4 safety light curtain from the F3SJ-A series, configured for hand protection with a 25 mm detection capability. The 20 mm beam pitch and 101 beams create a 2020 mm protective height, covering a vertical access zone from 0.2 m out to 7.0 m. That 25 mm detection means it catches fingers reaching into the hazard zone — finger-protection class per IEC 61496-1 — so it suits press brakes, assembly stations, and robotic cell perimeters where an operator can reach past the guarding plane.
If you are maintaining a safety circuit design that calls out this exact protective height and detection capability, the active status means you can continue specifying it without a redesign cycle.
Integration & Deployment
The 24 VDC supply is standard for safety relay or safety PLC interfaces; blanking and muting functions (listed features) allow the curtain to ignore fixed obstructions or automatically bypass during a material feed cycle.
The 25 mm detection capability sets the minimum object size the curtain sees — a 25 mm diameter finger or tool breaks at least one beam. The 2020 mm protective height covers the full vertical span of the hazard opening; paired with the 0.2 m to 7.0 m operating range, this curtain fits a guarding zone roughly 2 m tall and up to 7 m deep from the emitter to receiver. The 20 mm beam pitch (center-to-center spacing) determines the resolution: tighter pitch catches smaller objects but increases the beam count and controller processing load. At 101 beams, the F3SJ-A2020P25-TS balances coverage and response speed for a hand-protection application.
