Its 1870 mm protective height and 75 beams at a 25 mm pitch cover a vertical span of 1870 mm. The operating range runs from 0.2 m to 7.0 m.
Integration notes
The F3SJ-A1870P30 includes blanking and muting functions — blanking lets you ignore a fixed obstruction (like a fixture or conveyor rail) within the field, and muting temporarily suspends the curtain during a material pass-through without a full stop. Both are configurable through the controller, not hard-wired, so the same curtain adapts to different access patterns on the same line. Mounting hardware and alignment tools are separate; the curtain itself is a sealed column with a 25 mm beam pitch. The 75 beams mean the controller must handle that many channel inputs — verify your safety PLC or relay module has enough inputs or uses a dedicated F3SJ controller that serializes the beam data.
