Long-range distance measurement with millimeter accuracy.

When your industrial project requires indoor or outdoor measurement, Hokuyo's laser distance sensor is there for you. Our sensor has the capability to provide highly accurate non-contact readings whether the measurement target is a liquid, reflector, or natural surface. Equipped with two digital outputs, our distance sensor is ideal for proximity detection, collision avoidance, positioning applications, and more. Don't rely on just any laser distance sensor; rely on a Hokuyo laser distance sensor. Check out our available product below or contact us today for more information about our sensor technologies.

Laser Distance Sensor FAQs

They’re used across industries for:

  • Robotics & automation: Positioning robotic arms with millimeter precision.
  • Material handling: Detecting pallet height, spacing on conveyors, or crane positioning.
  • Quality control: Dimension verification, thickness measurement, and alignment checks.
  • Logistics: Monitoring loading/unloading processes or inventory positioning.

Depending on the model, accuracy can be as fine as ±3.0 mm over ranges up to 180 meters. This makes them ideal for high-precision tasks like component alignment, welding, or assembly.

Single-line sensors: Measure precise distance at one point—perfect for applications requiring pinpoint accuracy (e.g., crane lifting heights).

Area-scanning sensors: Cover wide fields of view, better suited for navigation, mapping, or collision avoidance.

Yes. Advanced models like Hokuyo’s PGL Series are designed to perform reliably on shiny metal, dark rubber, glass, and other challenging surfaces - making them adaptable across industries.

Many sensors are IP65-rated, meaning they resist dust, moisture, and vibration. This ensures consistent performance in warehouses, factories, and outdoor settings.

With output rates up to 100 Hz, they deliver near real-time feedback—critical for high-speed automation lines and robotic applications.

Laser distance sensors can integrate via Ethernet, RS-232, or RS-422, making them easy to connect to PLCs, controllers, and automation systems.

Unlike ultrasonic sensors, laser distance sensors are less affected by noise, temperature, or surface conditions. They provide more consistent results across a variety of materials and environments.

Minimal upkeep is required. Routine cleaning of the optical window ensures accuracy, but they’re designed for long-term, reliable operation with little intervention.
