Hokuyo UST-05LN / UST-05LNP / UST-10LN / UST-20LN / UST-30LCN / PBS-03JN

Precision Obstacle Detection for Intelligent Automation

The Hokuyo UST and PBS series are compact obstacle detection and area monitoring sensors designed for reliable performance in industrial automation, AGV/AMR navigation, and safety monitoring applications. The UST series offers laser-based LiDAR scanning with a wide 270° field of view and multiple detection ranges from 5 m up to 30 m, featuring flexible area configuration, fast response times, and NPN or PNP output options to suit different control systems. The PBS-03JN complements the lineup with an infra-red LED–based area scanner optimized for short-range obstacle detection, providing configurable detection zones, multiple outputs, and robust performance in harsh industrial environments. Together, these models deliver scalable, accurate, and dependable obstacle detection solutions for both compact and large-area applications.
