The 1270mm protective height and 26 beams at 50mm pitch cover a vertical access zone of that height; the 0.2m to 9.0m operating range gives flexibility for machine guarding across a typical cell width. IP65 rating means the emitter and receiver housings withstand hose-directed water and dust ingress — suitable for washdown environments in food processing or wet machining lines, not submersion. Supply is 24VDC, standard for safety circuits. ## Deployment context Mounts as a through-beam pair guarding a hazard zone access point — typical on press brakes, assembly stations, or robotic cells where a person entering the area must stop the machine. The blanking and muting functions (fixed blanking for a workpiece that stays in the field, muting to temporarily override the curtain for a pallet pass) are configured via the controller, not the sensor heads themselves. The 55mm detection capability means it catches a leg or torso reaching into the guarded area, but a hand or finger can pass undetected — pair with a finer-pitch curtain (14mm or 20mm) if hand protection is required.","metaTitle":"Omron F3SJ-A1270P55 Safety Light Curtain, 55mm Detection, 12","metaDescription":"Omron F3SJ-A1270P55 safety light curtain, 55mm detection capability, 1270mm protective height, 26 beams at 50mm pitch, IP65, 24VDC.

This is classified as leg/body protection — it catches a person entering the hazard zone but will not detect a hand or finger. For hand protection, a 14mm or 20mm pitch curtain is required."},{"question":"What is the protective height and beam count?","answer":"The protective height is 1270mm, achieved with 26 beams at a 50mm pitch. This covers a vertical access zone of that height."},{"question":"What IP rating and supply voltage does it use?","answer":"IP65 rated — dust-tight and protected against water jets, suitable for washdown environments. Supply voltage is 24VDC, standard for safety circuits."},{"question":"What special features does it support?","answer":"It supports blanking (fixed blanking for a stationary object in the field) and muting (temporary override for material handling pass-through).
