What this light curtain does on the line
That 25 mm figure means it catches fingers and hands reaching into a hazard zone — the standard finger-protection threshold under IEC 61496-1. The 13 beams cover a 260 mm protective height, which suits guarding a small access point or a conveyor infeed where you need a compact curtain, not a full-body height. Operating range is 0.2 m to 9.0 m, so it works across a typical machine cell width. Built-in blanking and muting functions let you configure the curtain to ignore fixed obstructions (like a machine frame) or temporarily bypass beams during a pallet pass-through, without external logic modules. That saves a DIN-rail slot and reduces wiring.
The 25 mm detection capability and 20 mm beam pitch are the pair that decide whether this curtain protects hands (25 mm) or just arms/body (40 mm+). At 25 mm, it meets the finger-protection standard for most point-of-operation guarding. The 260 mm protective height is the actual guarded zone — measure your opening height against that, not the overall housing length. Operating range of 0.2 m to 9.0 m covers short-reach to mid-span applications. The 0.2 m minimum is short enough for a press infeed; the 9 m max handles a conveyor zone across a cell. Temperature range of -10°C to 55°C is typical for indoor industrial environments — not rated for freezer or high-heat zones without additional enclosure.
