- Product Basic Information
Product Name：G03001A,G03001B.
Product Model：G03001APW,G03001BPW.
2.Product Description
Product Application：The G03001A/G03001B is a 360° absolute angular position sensor based on magnetic field encoding, delivering 14-bit high-resolution digital output.Under linearity-calibrated conditions in an external MCU-based test system, it achieves a maximum system accuracy of 0.06°. G03001A supports SPI interfaces, while G03001B supports I2C interfaces.It is designed to measure the absolute angular position of a magnet, with the system comprising Hall sensors array, two ADC and DSP.The zero-degree reference position can be programmed via commands, eliminating the need for mechanical alignment and helping designers reduce development time.
Scope of Application： Motor control (BLDC/PMSM),Robotic joint encoders,Industrial automation (rotary encoders),Drone gimbals, servo control,Consumer electronics (knobs, dials).
