What This Light Curtain Covers
That 25mm figure means it catches a hand or finger reaching into the hazard zone before contact happens — it's the standard spec for point-of-operation guarding where you need to stop a press or robot cell when someone reaches in. The 20mm beam pitch and 104 beams give it a 2080mm protective height, so it'll cover a tall opening on a machine guard or a conveyor infeed. Operating range runs from 0.3m out to 20.0m, which gives you flexibility to set it back from the hazard or use it across a wide aisle. Power is 24VDC, standard for safety circuits in most panels. The IP65/IP67/IP67G rating means the housing and optics handle washdown — oil resistant, dust tight, waterproof — so it'll survive on a food line or in a machining cell where coolant sprays are the norm.
Built-in Features for the Line
This curtain includes blanking and muting functions built in — no separate controller module needed for those. Blanking lets you block out a fixed object (like a fixture or conveyor frame) that sits in the light field without triggering a stop. Muting lets you temporarily override the curtain during a material pass, like when a pallet moves through the protected zone. Both are configurable through the standard setup, which saves panel space and wiring compared to adding external logic. The 25mm detection capability is the key number for compliance — it meets the hand-protection requirement under IEC 61496-1/2 for Type 4 safety light curtains. That means it's rated to stop a machine fast enough to prevent injury at typical approach speeds.
