What the 20 mm Detection Capability Means on the Line
The Omron F3SJ-A0455P20-TS is a Type 4 safety light curtain from the F3SJ-A series, designed for finger and hand protection per IEC 61496. The 20 mm detection capability means it reliably catches a 20 mm diameter object — roughly the width of a finger — reaching into the hazard zone. With a 15 mm beam pitch and 30 beams spanning a 455 mm protective height, the curtain covers a 0.2 m to 9.0 m operating range, so it suits guarding a press brake, robotic cell, or conveyor infeed where an operator's hands approach the danger point.
Rugged Enough for the Nacelle, Practical for the Panel
Rated IP65 — dust-tight and protected against water jets — the F3SJ-A0455P20-TS survives washdown environments and the airborne grit of a nacelle or a machining center. Blanking and muting functions are built in, so you can program fixed obstructions (like a fixture) out of the detection zone, or mute the curtain during a part pass-through without a separate controller.
