Product overview
The Wuxi Beiwei Sensing Technology BW-IMU125E is an inertial sensing component for integration into unmanned aircraft, robots, stabilization systems and other mobile equipment. Its sensing architecture combines a gyroscope with an accelerometer measuring along the X, Y and Z axes, with CAN output and a specified output frequency of 500Hz. Nonlinearity, orthogonality and temperature compensation are included, alongside high-level EMC protection. The hardware is an inertial measurement unit rather than a flight platform or airframe kit.
Mechanical integration dimensions are given for both packaged and bare-board configurations: 97 × 63 × 27.2mm and 60 × 54 × 6mm respectively. Bare-board length and width may each vary by ±1mm, with actual dimensions governing fit. Electrical integration requires 9-36V DC, with operating current of 30mA and a 40mA maximum. Operation spans -40 to 85°C. Measurement limits are ±400°/sec for the gyroscope and ±2g for acceleration; bias-stability figures depend on the specified measurement interval and temperature conditions.
