IMU-1221-R02 Compact Inertial Measurement Unit

The ATI MEMS-based IMU is ideal for precision motion and attitude measurement in harsh environments

Image of Analog Technologies IMU-1221-R02 Compact Inertial Measurement Unit The IMU-1221-R02, developed by Analog Technologies, is a compact inertial measurement unit (IMU) designed for motion and attitude tracking in dynamic environments. Utilizing MEMS accelerometers and gyroscopes with advanced Kalman filtering, this IMU delivers precise angular velocity (±400°/s) and acceleration (±2 g) measurements. Its rugged IP67-rated housing, wide temperature range (-40°C to +85°C), and compensation algorithms ensure stability in harsh conditions. With RS232, RS485, and TTL output options, it integrates seamlessly into industrial and robotic systems. The IMU includes serial port debugging software for real-time data visualization and calibration. The unit complies with national standards for static calibration (e.g., GB/T 191 SJ 20873-2003), and embedded temperature compensation ensures accuracy across extreme operating conditions.
