Honeywell HG1120 IMU


The HG1120 IMU from Honeywell has reached End of Life (EOL). The last date to place final orders for the product listed above is September 30, 2020. Please contact us for recommendations on a replacement product.



The HG1120 IMU from Honeywell is a MEMS (Micro-Electro-Mechanical System) based IMU (Inertial Measurement Unit) that can be used for motion sensing requirements of a range of applications across various markets.

The HG1120 IMU has a wide input voltage range and various industry standard communication interfaces, making it easy to integrate into a variety of architectures. The light weight, small size, and low power consumption makes the HG1120 ideal for most applications, including AUVs, agriculture, robotics, industrial equipment, stabilized platforms, survey/mapping, UAVs, transportation, and UGVs.

The HG1120 includes MEMS magnetometers, accelerometers and gyroscopes. The HG1120 also uses an internal environmental isolation system to reduce unwanted inputs often found in real world applications. This internal isolation and other design features ensure the HG1120 is rugged enough to meet the requirements of the most demanding environments.


  • Range of user configurable options available with filtering and selectable output data rates
  • World class inertial sensor compensation, calibration and development
  • Proven ruggedness, dependability and reliability
  • Standard RS-422 Asynchronous and SPI Interface protocols, while CAN interface is available upon request
