Omron F3SJ-B1665P25 Light Curtain, Hand Protection 25mm, 166

The Omron F3SJ-B1665P25 is a Type 4 safety light curtain from the F3SJ-B series, designed for hand protection with a 25mm detection capability. That 25mm detection means it reliably catches fingers reaching into the hazard zone — finger-protection class per IEC 61496-1. The 1665mm protective height and 20mm beam pitch (82 beams total) define the guarded area; anything passing through that curtain trips the safety outputs. Operating range spans 0.2m to 7.0m, so it works across a typical machine guarding gap — close enough for a press infeed, far enough for a conveyor entry. Supply is 24VDC, standard for safety circuits. IP65 rating means the housing and optics withstand washdown and dust ingress — suitable for food-and-bev lines or wet machining areas. Built-in blanking and muting functions let you configure fixed or floating blanking zones (to ignore a workpiece passing through) and muting sensors for material handling. That saves an external safety controller for simple applications.
