The 15 mm beam pitch and 150 beams give it a 2255 mm protective height, so it covers a full machine opening or hazard zone in a single pair — no stacking multiple curtains. The 0.2 m to 7.0 m operating range means it works across short reach-in zones up to longer perimeter guarding distances. A 20 mm detection capability means it catches fingers reaching into the hazard zone (finger-protection class per IEC 61496). The 15 mm beam pitch is tight enough that a hand or finger can't slip between beams without being detected. For a machine builder, that translates to a minimum safe distance calculation based on 20 mm resolution — tighter than a 30 mm hand curtain, which allows closer mounting to the pinch point. This curtain is a safety device for guarding hazardous machine areas — presses, robots, assembly stations, packaging lines. The IP65 rating (dust tight, water resistant) means the emitter and receiver housings handle washdown environments and dusty factory floors without needing an extra enclosure. Blanking and muting functions are built in. Blanking lets you block selected beams for workpiece pass-through without stopping the machine — useful for fixtures or conveyor slots that break the beam intentionally. Muting temporarily bypasses the curtain during a non-hazardous part of the cycle, like a pallet entering a station. Both features reduce false trips and keep production moving. ## What the buyer needs to know for the RFQ When you source this through an industrial distributor, the key confirmation points are the cable length and connector type — the F3SJ-A series offers several cable options, and the P20 suffix in the order code specifies a particular one. The 150 beams and 2255 mm protective height are fixed, so verify your guarded opening height matches. The 0.2 m minimum range means the curtain can't be mounted closer than 200 mm to the emitter/receiver — factor that into your standoff distance.","metaTitle":"Omron F3SJ-A2255P20 Safety Light Curtain, 20mm Finger/Hand,","metaDescription":"Omron F3SJ-A2255P20 safety light curtain. 20mm detection, 2255mm protective height, 150 beams, 15mm pitch.

The 15 mm beam pitch means a finger cannot pass between beams undetected. This resolution allows the curtain to be mounted closer to the hazard than a 30 mm hand curtain would permit, reducing the minimum safety distance."},{"question":"What is the protective height and how many beams does it have?","answer":"The protective height is 2255 mm, achieved with 150 beams at a 15 mm pitch. This covers a full machine opening or tall hazard zone in a single pair of emitter and receiver units."},{"question":"What environment is the IP65 rating suitable for?","answer":"The IP65 rating means the housing is dust tight and protected against water jets. It is suitable for washdown environments, dusty factory floors, and outdoor installations under cover. No additional enclosure is required for these conditions."},{"question":"What features does the F3SJ-A2255P20 support?","answer":"It supports blanking (fixed and floating) and muting functions. Blanking allows selected beams to be ignored for workpiece pass-through. Muting temporarily suspends the curtain during non-hazardous machine cycles. Both reduce nuisance trips without compromising safety."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/omron/F3SJ-A2255P20","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/omron/F3SJ-A2255P20 when reusing this data.
