Its 55 mm detection capability means it reliably detects a human leg or torso entering the field — this is the finger-safe threshold for body protection per IEC 61496-2, not for hand or finger detection. The 1620 mm protective height covers the full vertical reach of a standing operator's lower body, and the 0.2 m to 9.0 m operating range gives flexibility for mounting depth in the guarded zone. The 33 beams at 50 mm pitch create the detection field; the 55 mm detection capability is the smallest object the curtain can reliably block for. Supply is 24 VDC, standard for safety circuits in industrial control panels. Built-in blanking and muting functions allow the curtain to ignore fixed obstructions (like a conveyor frame) or temporarily suspend guarding during a workpiece pass-through without a separate bypass module. This reduces external safety relay complexity when the application needs selective exclusion zones.

Frequently asked questions
What does the 55 mm detection capability mean for guarding?
The 55 mm detection capability means the light curtain will reliably detect a human leg or torso entering the protected area. This is classified as body protection per IEC 61496-2 — it will not detect fingers or hands, so it is not suitable for point-of-operation guarding where hand access is possible.
What is the operating temperature range for this light curtain?
The F3SJ-A1620P55 is rated for an operating temperature range of -10°C to 55°C, which covers most indoor industrial environments but may require additional heating or cooling for extreme ambient conditions.
What compliance documentation is available for the F3SJ-A1620P55?
As an Omron safety component, the F3SJ-A series carries CE marking for the European market and is designed to meet applicable IEC/EN 61496 safety standards. Specific documentation such as RoHS or UL declarations should be verified against the manufacturer's official documentation for the exact production batch.
