LDM 5x Laser Distance Sensors measure with millimeter accuracy at 200 meter measuring Range

LUMOS series laser distance sensors deliver measuring results accurate to the millimeter even for radiating objects or in bright sunlight conditions.

LUMOS Series

The LUMOS series of laser distance sensors has a measurement frequency of 100 Hz enabling high precision measurements or distance monitoring up to 200 meters for reflective surfaces. The measuring distance for natural surfaces (< 10% reflectance) is 85 meters. Both the 200 meter and 85 meter measurements have an accuracy of ±1 mm. LUMOS series devices are ideal for measuring hot surfaces such continuous cast steel slabs and billets, thin cast slabs, blooms, etc.. The LUMOS series excels in bright light outdoor conditions where large quantities of stray, direct, and indirect sun light may interfere.

LUMOS series devices contain an OLED touch screen as the MMI for easy configuration and parameterization. The LUMOS series uses a visible (red) Eye Safe Class 2 laser emitting at 655 nm which also may be used to align the range finder visually to the target. These devices have met the stringent IP67 / NEMA 6 requirements. The LUMOS series has fully integrated RS-232, RS-422, RS-485, Profibus, and SSI compatible connection options, switching outputs and the ability to switch between analog and digital output.

Options for the LUMOS series laser distance sensors include: internal heater (for cold climate operations), three digital outputs / trigger for remote signal generation and control, plus a case hardened chassis for EMI protection, allowing this small, compact unit to be fully and easily integrated into existing and new systems and automation plants.


  • Fast: Measurement frequency 100 Hz.
  • Accurate: ±1 mm accuracy, within 85 m range on 10% reflective surface, and 200 m range on radiant surface.
  • Flexible: Capable of measuring radiant, natural (< 10% reflective), reflective, and sunbathed (brilliant lighted) surfaces.
  • Robust: IP67 / NEMA 6 certified.
  • Easy to operate and integrate: MMI utilizes an OLED touchscreen along with the standard suite of RS, SSI, analog, and digital connectors.
  • Safe: Utilizes visible 655 nm eye-safe class 2 laser for both measuring and visual alignment.

Fields of application

  • Automation technology: Cast slab, billet, bloom, and coil length measurements, even radiant, in real time.
  • Industrial metrology: Non-contact measurement of geometric dimensions such as length, height, thickness and position.
  • Logistics, transport and conveyor technology: Positioning of transport and loading systems, and vehicles.
