Product overview
The Wuxi Beiwei Sensing Technology BW-IMU610 is an inertial sensing component for integration into navigation, attitude-measurement and stabilization systems. Its compact physical envelope measures 44.8 mm long, 38.6 mm wide and 21.5 mm high, defining the space occupied by the unit within a host assembly. The architecture includes gyroscope and accelerometer sensing, orthogonal compensation and an RS422 output interface. Intended applications span unmanned aircraft, underwater robot navigation, autonomous-driving navigation platforms, pipeline surveying, model attitude-angle measurement and platform stabilization.
The standard accelerometer range is ±20g, with ±5g and ±50g available as options; the gyroscope range is ±500°/s. The unit supports a maximum output frequency of 500Hz, with 200Hz bandwidth and a 200ms startup delay. Its temperature range is -40°C to +85°C, and temperature compensation is a stated feature. Performance conditions matter: the less than 1°/h gyroscope bias-stability figure uses 10s smoothing at room temperature, while the 10°/h full-temperature bias figure applies without temperature compensation.
