A 55mm detection capability means it's sized for leg and body protection, not hand or finger detection. The 1220mm protective height covers the access zone for a standing operator reaching into a hazard. The 50mm beam pitch and 25 beams define the resolution: a 55mm object anywhere in the 0.2m to 9.0m operating range trips the output. The IP65 rating means the emitter and receiver housings are dust-tight and protected against water jets — suitable for washdown environments in food processing or general manufacturing, though not for submersion. ## Deployment context This light curtain guards a hazard zone — typically a press, robot cell, or conveyor infeed — where a person's legs or body entering the area must stop the machine. The 24VDC supply powers both the emitter and receiver; the receiver outputs a safety-rated signal (OSSD) that connects to a safety controller or safety PLC. The blanking and muting functions let the curtain ignore fixed obstructions (blanking) or temporarily disable itself during a material feed cycle (muting), which is common on automated assembly lines where a pallet passes through the guarded opening.","metaTitle":"Omron F3SJ-A1220P55 Safety Light Curtain, 55mm Detection, 12","metaDescription":"Omron F3SJ-A1220P55 safety light curtain with 55mm detection capability, 1220mm protective height, 0.2m-9.0m range.

This is classified as leg and body protection per safety standards — it will not detect a hand or finger. For hand protection you would need a curtain with a 14mm or 30mm detection capability."},{"question":"What is the protective height and how do I select the right model?","answer":"The protective height is 1220mm. This is the height of the detection zone, not the physical height of the housing. You select a model whose protective height covers the full reach-in zone of the hazard. The F3SJ-A series offers multiple protective heights; the 1220mm version suits a standing operator guarding a waist-to-shoulder access area."},{"question":"What is the operating range and how does it affect installation?","answer":"The operating range is 0.2m to 9.0m between the emitter and receiver. This is the maximum separation distance for reliable detection. For a 9m range, the emitter and receiver must be aligned within the specified angular tolerance. Dust or condensation on the optics reduces effective range, so keep the windows clean in dirty environments."},{"question":"Is the F3SJ-A1220P55 suitable for washdown environments?","answer":"Yes, the IP65 rating means the housings are dust-tight and protected against water jets. This is suitable for washdown in food processing or general manufacturing areas. It is not rated for submersion (IP67 or IP68)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/F3SJ-A1220P55","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-A1220P55 when reusing this data.
