O1D106 ifm Long-Range Laser Sensor, Crane Positioning, O1D Series

O1D106 Laser Distance Sensor: Long-Range Measurement for Crane Systems

The ifm O1D106 measures distance with a class 2 laser. It reaches up to 75 m with a reflector. Background suppression covers 75 to 150 m. Therefore, it suits crane positioning and long-range control. The type code is O1DLF3KG.

FAQ

Q: How far can the beam reach without a reflector?

A: Background suppression covers 75 to 150 m. Reliable distance values need the prism reflector.

Q: Why does accuracy change at 33 Hz?

A: Faster sampling shortens the averaging time. Repeatability then drops to ±43 mm and accuracy to ±63 mm at 70 m.

Q: Can I use analog and digital outputs at the same time?

A: Yes, within limits. You get two digital PNP outputs and one analog output. You choose the analog type: current or voltage.

Q: What happens if the supply drops below 18 V?

A: The sensor may reset or show unstable readings. Keep the supply within 18 to 30 V DC and use class 2 supply wiring.

Q: How do I set the measuring span in the field?

A: Use the teach function or IO-Link. Set the span to your real crane travel. This trims the analog signal to your PLC range.

Q: Do I need to clean the glass lens?

A: Yes, dust on the lens shortens the range. Wipe the glass with a soft cloth at each service visit.
