3-Axis Gyroscope Component - Industrial Grade MEMS Sensor

Product Specifications

Technical details and manufacturing context for 3-Axis Gyroscope

Definition

The 3-Axis Gyroscope is a component used in the manufacturing of computer, electronic, and optical products. It is a core element of an Inertial Measurement Unit (IMU) that detects and measures the rate of rotation (angular velocity) in three-dimensional space. This device provides critical orientation and rotational motion data for navigation, stabilization, and motion tracking systems. It operates on the principle of the Coriolis effect, where a vibrating or rotating mass experiences a force proportional to the angular velocity when the device rotates. Modern MEMS (Micro-Electro-Mechanical Systems) gyroscopes use vibrating structures whose resonant frequency or amplitude changes with rotation. The device is typically fabricated from silicon (MEMS) and may incorporate piezoelectric crystals and supporting electronics (ASIC). Key parameters include a measurement range of ±250 to ±2000 °/s, bias stability of ≤0.8 °/h, angular random walk of ≤0.05 °/√h, nonlinearity of ≤0.1% FS, bandwidth of 100–1000 Hz, supply voltage of 3.0–5.5 V DC, current consumption of ≤10 mA at 3.3 V, operating temperature of -40 to 85 °C, shock resistance of 10000 g (0.1 ms half-sine), digital interface (SPI/I2C), package size of 4.5×4.5×1.0 mm (LGA), and weight of ≤0.5 g. These values are typical reference ranges and must be verified for the specific model and application with the legal manufacturer or supplier. The product is intended for industrial-grade applications. For accurate selection, consider the required measurement range, bias stability, bandwidth, and interface compatibility. Verification questions should include confirming the exact performance over temperature, power supply requirements, and mechanical robustness. Maintenance signals may include drift in bias or increased noise, indicating potential degradation. Failure boundaries include operation outside specified temperature, voltage, or shock limits, which may lead to permanent damage. Always consult the manufacturer's datasheet for detailed specifications and application notes.

Working Principle

The 3-Axis Gyroscope measures angular velocity using the Coriolis effect. Inside a MEMS gyroscope, a proof mass is driven to vibrate continuously. When the device rotates, the Coriolis force causes a displacement perpendicular to the vibration direction, which is proportional to the angular velocity. This displacement is sensed capacitively or piezoelectrically, and the resulting signal is processed by an ASIC to output digital data. The device measures rotation around three orthogonal axes (X, Y, Z) simultaneously, providing three-axis angular rate information.
