SensorDynamics: New 6-Axis Inertial Measurement Unit (6DoF IMU)

  • Combo sensor detects angular rate and acceleration in all three spatial axes
  • Temperature-compensated and calibrated combined sensor SD746 integrates functionality of six discrete sensors in one small package
  • Ideal for detecting motion and stabilization in consumer goods and industrial sectors

GRAZ, Austria--()--SensorDynamics, a producer of one-dimensional and multidimensional inertial and wireless sensors, is adding to its family of compact QFN40 packaged combined sensors: the new micromechanical SD746 combo sensor with six degrees of freedom comes with three measurement axes each for angular rate and acceleration. Here SensorDynamics is taking the next logical step toward higher density of integration in its robust and reliable inertial sensors. The SD746 features digital I²C and SPI interfaces plus wide measurement ranges of ±2048°/s for angular rate and ±8 g for acceleration. That makes it flexible enough to use in a wide range of measurement applications in the consumer goods industry and automation. Plus, the SD746 is temperature-compensated and factory calibrated, resulting in an extremely small offset error and temperature drift.

Sensor characteristics and applications

The SD746 is scaled for an operating voltage of 2.55 through 3.6 V and an operating temperature range of -40 to +85°C. The maximum offset error at room temperature is ±5°/s for the gyroscope signal and ±0.1g for the accelerometer signal. Sensitivity error at room temperature is ±2% for the gyroscope and acceleration signal, respectively. The SD746 also features a special power-off mode in which consumption is zero, the SPI interface remaining high-impedance so that the sensor need not be separated from the bus.

“We’re the first producer worldwide to go to market with a fully characterized and specified 6 x 6 x 1.2 mm 6DoF IMU including evaluation boards,” says SensorDynamics CEO Hubertus Christ.

Given its moderate power consumption and small-scale package, the SD746 is suitable for industrial applications and battery-powered consumer goods, such as cell phones and smart phones, notebooks and netbooks, remote controls, game consoles, or digital cameras and camcorders. The SD746 also integrates a continuously running self-test that makes it ideal for sophisticated instrumentation & control applications in industry, such as robot control and navigation.
