Product overview
The Wuxi Beiwei Sensing Technology BW-MINS525E provides inertial attitude measurement and heading retention for integration into unmanned aircraft, robots, vehicles and stabilized platforms. Its CAN interface supports a maximum output frequency of 500Hz, while power requirements are 9-36V DC and 30mA operating current, with a 40mA maximum. Attitude specifications distinguish 0.1° dynamic accuracy from 0.01° static accuracy. Measurement coverage extends to ±90° in pitch and ±180° in roll, with heading retention accuracy of 0.1°/60s.
Physical configurations comprise a packaged unit measuring 97 × 63 × 27.2 mm and a bare board measuring 60 × 54 × 6 mm. The bare board’s length and width may vary by ±1mm, so its integration space must accommodate that qualification. Weight is 280g including the cable. The system includes temperature compensation and operates from -40 to 85°C, with storage permitted from -55 to 100°C. Electrical and mechanical specifications include GBT17626 electromagnetic compatibility, insulation resistance of at least 100 MΩ, and 2000g shock resistance for 0.5ms, three times per axis.
