Product details

What this light curtain does

Its 55 mm detection capability means it catches a leg or torso entering the hazard zone, but it will not detect a hand or finger — that is the key fit decision for this part. The 420 mm protective height and 9 beams at 50 mm pitch define the guarded area; the operating range spans 0.2 m to 9.0 m, so it handles both close-in and across-the-aisle guarding.

Deployment context

Rated IP65 — dust-tight and protected against water jets — so it holds up on washdown lines, outdoor conveyor transfers, or anywhere hose-down cleaning is routine. The 24 VDC supply is standard for safety circuits; it mates directly to a safety relay or safety PLC input without a separate power supply in most panels. Blanking and muting functions are built in, which lets the curtain ignore fixed obstructions (blanking) or temporarily suspend guarding during a material pass-through (muting) — useful on palletizing cells or automated guided vehicle interfaces.

Frequently asked questions

What is the detection capability and what does it protect?

The detection capability is 55 mm, which means the light curtain is designed for leg and body protection per IEC 61496-2. It will not detect hands or fingers passing through the beam array.

What is the protective height and number of beams?

The protective height is 420 mm, achieved with 9 beams spaced at 50 mm pitch. This covers a lower-body access zone typical for robot cell or machine guarding applications.

What is the operating range and supply voltage?

The operating range is 0.2 m to 9.0 m, suitable for both close-proximity guarding and across-aisle installations. Supply voltage is 24 VDC, standard for safety circuits.

What environmental rating does it carry?

IP65 — dust-tight and protected against water jets. Suitable for washdown environments, outdoor conveyor lines, and industrial areas where hose-down cleaning is routine.
