Product details

Its 55 mm detection capability means it reliably detects a person's leg or full body entering the field — that's the spec that decides whether it guards a hazard zone properly. The 50 mm beam pitch and 19 beams create a 920 mm protective height, so it covers a vertical access area just under a meter tall. Operating range runs from 0.2 m to 9.0 m, which gives you flexibility to mount it across a machine opening or a conveyor access point without worrying about the exact standoff distance. Runs on 24 VDC, standard for safety circuits in most control panels. IP65 rating means the housing is dust-tight and can handle hose-down — suitable for washdown environments in food processing or general manufacturing where you need to clean the machine without pulling the light curtain.

Features for guarding flexibility

Built-in blanking and muting functions let you configure the light curtain for more complex guarding setups. Blanking allows you to ignore fixed objects like a machine frame that sits in the field of view, while muting temporarily suspends the safety output during a defined material pass-through — useful on conveyor infeed or palletizing stations where the load needs to break the beam without stopping the machine. These are configurable features, not add-on modules, so they save panel space and wiring.

Frequently asked questions

What does the 55 mm detection capability mean for guarding?

The 55 mm detection capability means the light curtain reliably detects a leg or full body entering the protected area. That's the spec that determines whether it meets the required safety distance and resolution for your application — typically used for access guarding where hand detection isn't needed.

What is the protective height and how many beams does it have?

The protective height is 920 mm, achieved with 19 beams at a 50 mm pitch. That covers a vertical opening just under a meter tall, suitable for guarding a machine access point or conveyor infeed.

What is the operating range and supply voltage?

The operating range is 0.2 m to 9.0 m, giving you flexibility in mounting distance. Supply voltage is 24 VDC, standard for safety circuits.

What IP rating does it have and what does that mean for installation?

IP65 rated — dust-tight and water resistant. That means it can handle washdown in food processing or general manufacturing environments without needing an extra enclosure.
