Its 15 mm beam pitch and 26 beams create a 395 mm protective height — sized for guarding a single-axis hazard zone like a press or pick-and-place cell entry point. Detection capability of 20 mm means it catches fingers reaching into the hazard zone (finger-protection class per IEC 61496-1). The 0.2 m to 9.0 m operating range gives flexibility for both tight machine guarding and wider access areas. IP65 rating means the sensor housing and optics withstand washdown — suitable for food-and-bev lines or wet machining environments where dust and water spray are present. Built-in blanking and muting functions let the curtain ignore fixed obstructions (like a conveyor frame) and automatically bypass during a material pass-through cycle, which is common in automated assembly cells. ## Integration notes Runs on 24 VDC supply, standard for safety relay and PLC-based safety circuits. The 26-beam array draws loop power consistent with the F3SJ-A series; plan for a dedicated 24 VDC supply rail in the panel to avoid brownout on the safety loop. IP65 enclosure means the emitter and receiver heads can be surface-mounted on machine frames without additional guarding, but cable glands and connector orientation matter for washdown compliance — verify the gland entry is oriented downward to avoid pooling.","metaTitle":"Omron F3SJ-A0395P20 Light Curtain, 20mm Detection, 395mm Hei","metaDescription":"Omron F3SJ-A0395P20 safety light curtain, 20mm finger/hand detection, 395mm protective height, 15mm beam pitch, 26 beams, 0.2-9.0m range, IP65, 24VDC.

This qualifies as finger protection per IEC 61496-1, suitable for guarding pinch points and access openings where hand entry is possible."},{"question":"What is the protective height and how is it calculated?","answer":"The protective height is 395 mm, determined by 26 beams at a 15 mm pitch. This height covers the vertical zone from the bottom beam to the top beam, so the curtain must be mounted so the hazard is fully within that 395 mm span."},{"question":"What ingress protection rating does it carry?","answer":"IP65, meaning it is dust-tight and protected against water jets from any direction. This makes it suitable for washdown environments in food processing or machining cells, but not for submersion or high-pressure spray (IP67/IP69K would be needed for those)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/F3SJ-A0395P20","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-A0395P20 when reusing this data.
