Product overview
The iFlight AS5048A Magnetic Encoder measures the absolute rotation angle of a magnet through contactless sensing. Its IC combines Hall sensors, an analog-digital converter and digital signal processing, with a 14-pin TSSOP package measuring 5x6.4mm. Full-scale resolution is 14 bits, or 0.0219°/LSB. Maximum system accuracy is 0.05° when an external microcontroller performs linearization and averaging. SPI and PWM interfaces provide position output, while programmable zero positioning removes the need to mechanically align the magnet’s zero position. Multiple AS5048 ICs can also connect in a daisy chain for serial readout.
Applications include robotic joint position detection, industrial motor position control, medical robots and fitness equipment. An internal regulator supports 3.3 V or 5 V supplies, and the ambient operating temperature range is -40°C to +150°C. The sensor tolerates misalignment, air gap and temperature variations, and external magnetic fields, with a magnetic field input range of 30mT – 70mT. The assembly includes an aluminum alloy part; mounting the metal plate requires motor screw holes, otherwise a custom mounting arrangement is needed. Supplied equipment comprises one AS5048A with wires. The motor is not included.
