High-Precision 2D LiDAR for Compact Industrial Applications
The HOKUYO UST-05LN is a cutting-edge 2D LiDAR sensor engineered
for industrial automation tasks demanding exceptional accuracy in
confined spaces. With a 5-meter detection range (extendable to 15
meters under optimal conditions) and a 270° scanning angle, it
delivers comprehensive environmental perception for applications
such as collaborative robot (cobot) guidance, small AGV navigation,
and precise object detection in manufacturing cells. Its Class 1
infrared laser (905 nm) ensures eye-safe operation while achieving
±20 mm accuracy and σ <15 mm repeatability, setting a new
standard for precision in its class. The sensor’s compact design
(50×50×70 mm, 130 g) and IP65-rated enclosure make it ideal for
integration into space-constrained systems, while its low power
consumption (150 mA typical) extends battery life in mobile
applications. Unlike the UST-05LX, which prioritizes range, the
UST-05LN enhances precision, making it better suited for tasks like
pick-and-place operations in electronics manufacturing.
Advanced Sensing for Dynamic Industrial Environments
Equipped with advanced signal processing algorithms, the UST-05LN
effectively filters ambient noise and interference, ensuring
reliable detection in challenging lighting conditions or
environments with reflective surfaces. Its 40 Hz scanning frequency
and 0.25° angular resolution enable high-speed, detailed mapping,
critical for real-time applications like collision avoidance in
shared workspaces. The sensor supports both Ethernet
(10/100BASE-TX) and RS-422 interfaces, facilitating seamless
integration with PLCs, robotic controllers, and IoT platforms.
While Sick’s TIM310 offers comparable compactness, the UST-05LN
distinguishes itself with its superior accuracy and multi-echo
capability, which can detect multiple objects in a single laser
beam path. This feature is particularly valuable in applications
involving transparent materials or overlapping targets.
Strategic Solution for Smart Factory Integration
The UST-05LN is designed to meet the evolving demands of Industry
4.0, offering compatibility with HOKUYO’s URG BENRI Plus software
for intuitive configuration and ROS middleware for streamlined
robotic integration. Its ability to generate dense point clouds
(7,200 points/sec) supports advanced analytics, such as occupancy
grid mapping and object classification, enhancing situational
awareness in automated systems. Compared to Velodyne’s 3D LiDARs,
which prioritize volumetric scanning, the UST-05LN delivers
cost-effective 2D coverage optimized for precision tasks, reducing
unnecessary data complexity and computational load. With CE, FCC,
and RoHS certifications, it ensures global compliance, while its
wide operating temperature range (-10°C to +50°C) makes it
versatile for diverse industrial settings. Whether deployed in food
processing, pharmaceutical manufacturing, or logistics automation,
the UST-05LN provides the accuracy and reliability needed to drive
efficient, safe operations.
