Safety Light Curtain for Hand Protection
The Omron F3SJ-A0260P25-TS is a Type 4 safety light curtain from the F3SJ-A series, designed for hand protection with a 25mm detection capability. That 25mm figure means it reliably detects a human finger or hand reaching into a hazard zone — the standard finger-protection threshold per IEC 61496-1. The 260mm protective height and 20mm beam pitch (13 beams total) define the guarded area: the curtain covers a 260mm vertical zone, and the 20mm spacing between beams ensures no gap larger than 25mm goes undetected. Rated for a 0.2m to 9.0m operating range, this curtain suits guarding applications where the transmitter and receiver are separated by up to 9 meters — typical for large machine access points or conveyor in-feed zones. The 24VDC supply is standard for safety circuits, and the IP65 rating (dust-tight, water-resistant) means the sensor housings withstand washdown environments common in food processing or automotive assembly lines. Built-in blanking and muting functions let the curtain ignore fixed obstructions (like a machine frame) or temporarily suspend guarding during a material pass-through — useful for palletizing cells or automated guided vehicle interfaces without adding external bypass relays.
No pin-compatible direct replacement exists within the F3SJ-A family at this protective height and detection capability — the 260mm/25mm combination is specific to this variant. If you're cross-referencing an existing installation, verify the protective height and beam pitch match your guarding envelope before committing the BOM line.
