# RoboSense E1R Solid-State 3D Lidar

> RoboSense E1R is an all-solid-state (flash) 3D lidar for robots. It covers 120° × 90° with 0.625° average resolution and gives about 260,000 points/s at 10 Hz. It reaches 30 m at 10 % NIST in 100 klux with a 0.1 m blind zone, uses automotive 1000BASE-T1 Ethernet with gPTP / PTP on a TE 6+2-pin connector, runs on 9–16 V at < 10 W, and is IP67 / IP6K9K, −40 to 85 °C, 95 × 42.6 × 69.5 mm, 330 g.
