Instruction: PTZ encoder/encoder motor dedicated as5048a rotation sensor 14-bit rotary position sensor digital angle (interface) and pulse width modulation output as5048a is a 14-bit rotary position sensor (previously called encoder) for absolute angle measurement and PWM (= Pulse Width Modulation) full rotation output at 360° based on non- magnetic sensor technology. The device is suitable for shaft applications with a simple two-pole magnet turning the sensor IC or below and the zero position can be programmed into the device with simple SPI commands. The absolute magnetic angular position resolution is 14 bits = 16384 position measurement, serial interface (SPI) with digital value per revolution. AS5048 provides PWM output and SPI or I2C interface to provide absolute angle measurement for the microcontroller. There is no need to consider the matching of the initial zero position of the chip and the magnet poles used in the mechanical design. Instead, the zero position can be programmed through simple SPI or I2C commands (without special programming equipment) as early as the assembly. AS5048 internal memory. AS5048 also has a very high working tolerance, including the deviation of the center position between the chip and the paired magnet, the deviation of the air gap between the chip and the paired magnet, and the temperature change between -40 and +150. The AS5048 magnetic rotary encoder can provide more accurate measurement. Its 14-bit measurement analog front end provides measurement resolution as low as 0.0219 degrees. Linearization and averaging processing are performed by the microcontroller, which can achieve angle measurement with an accuracy of 0.05 degrees.
