Overview

6DF (Six Degrees of Freedom) Series Inertial Measurement Unit, 6-D Motion Variant, 2 g accelerometer.

The Honeywell 6-D Motion Variant 6DF (six degrees of freedom) Inertial Measurement Unit (IMU) sensors are designed to provide motion, position, and navigational sensing from a durable single device over six degrees of freedom. This is achieved by using MEMS (microelectromechanical system) technology to sense translational movement in three perpendicular axes (surge, heave, sway) and rotational movement about three perpendicular axes (roll, pitch, yaw). Because the movement and rotation along the three axes are independent of each other, such motion is said to have "six degrees of freedom."

The 6DF Series IMU measures the motion of the equipment onto which it is attached and delivers the data to the equipment's control module using industry-standard CAN SAEJ1939 communications protocol, allowing the operator to focus on other equipment functions, enabling more precise control than can be achieved by using only the human eye, thus increasing safety, stability, and productivity.

The 6DF Series is also available in a 6 g accelerometer version:

6DF-1N6-C2-HWL: This version is much more tolerant of vibration and rugged environments than the 6DF-1N2-C2-HWL. This allows for optimum performance in harsh environments, with a small reduction in accuracy.

Product Features

  • Designed to Six Sigma standards: Six Sigma standards provide the highest level of product quality, performance, and consistency. Six Sigma provides confidence that the IMU will perform to specification. Some competitive products may be produced to much lower Sigma tolerances, which may result in some products not performing to the specification in some conditions
  • Industry-leading durability:
    • Aluminum housing protects device from damage due to stones, dust, dirt, pressure washing, and humidity, allowing for use in harsh and outdoor environments
    • Corrosion-resistance minimizes susceptibility to deterioration often experienced in saltwater environments
    • Compatible with chemicals such as diesel fuel, hydraulic oil, gas/ethylene glycol, brake fluids, urea, liquid lime, NPK fertilizer, ammonia hydroxide, and alkaline degreasers
    • IP67 and IP69k ratings provide resistance to weather
    • Wide operating temperature range withstands most thermal extremes, preventing package breakage
