Description
The Galileo G4D-LH120 is a 4D millimeter wave radar sensor developed by GalileoTime for security, industrial, and inspection applications requiring precise detection and velocity measurement at medium to long range. Using frequency-modulated continuous wave (FMCW) modulation, the G4D-LH120 achieves a range measurement window of 40 to 120 meters with a range accuracy of ±0.13 m, making it well suited to perimeter security, facility access monitoring, and infrastructure inspection tasks where reliable target distance data is essential. Speed measurement spans -120 km/h to +120 km/h with an accuracy of ±0.04 m/s, covering the full range of pedestrian, vehicle, and robotic targets in operational environments.
The sensor's field of view spans ±60° horizontally and ±30° vertically, giving broad coverage for area surveillance and multi-target tracking scenarios. Operating voltage is 12 V to 26 V DC, and the unit provides Ethernet, RS485, and relay connectivity for integration into robotics platforms, fixed monitoring systems, and industrial automation networks. IP67 ingress protection enables use in outdoor and harsh-environment conditions, and the wide operating temperature range of -40°C to +85°C covers extreme climate deployments. The sensor body measures 172.7 × 192.5 mm.
