Product overview
Wuxi Beiwei Sensing Technology’s BW-AH427C provides attitude and heading measurements for integration into unmanned aircraft, robotic controls and stabilized platforms. It supports both dynamic and static measurement, with 0.2° roll and pitch accuracy and 0.3° heading accuracy. Its measurement envelope covers pitch through ±90° and roll through ±180°, while the maximum output frequency is 500Hz. Modbus communication and selectable RS232, RS485 or TTL outputs provide the specified connections for integration with host electronics.
The hardware has packaged and bare-board configurations, measuring 60 × 59 × 29 mm and 44 × 35 × 11 mm respectively. Bare-board length and width may vary by ±1 mm, so that allowance matters when allocating mounting space. Power requirements are 9-36V DC at 30mA operating current, rising to a 40mA maximum. The temperature-compensated system operates from -40°C to +85°C, with storage permitted from -55°C to +100°C. These configurations constitute an attitude-reference component for integration into a larger system.
