Product overview
The BWSENSING BW-IMU125E combines gyroscope and accelerometer measurements in a CAN-output inertial measurement unit for integration into unmanned aircraft, robots, autonomous vehicles and stabilization systems. Its sensing architecture provides angular-rate measurement over ±400°/sec and acceleration measurement over ±2g on the X, Y and Z axes, with a 500Hz output frequency. Nonlinearity and orthogonality compensation accompany temperature compensation, while high-level EMC protection is another stated feature. The product is an integration component rather than a complete flight platform or airframe kit.
Two physical configurations define the installation space: the packaged product measures 97 × 63 × 27.2mm, and the bare board measures 60 × 54 × 6mm. Bare-board length and width may each vary by ±1mm, with actual dimensions taking precedence. Electrical integration requires 9–36V DC and allows for 30mA operating current, rising to a maximum of 40mA. Operation spans -40 to 85°C; storage spans -55 to 100°C. Bias-stability figures depend on the specified measurement interval, with accelerometer figures additionally qualified at 25°C.
