Magnetic Encoder Rotary Position Sensor (AS5600) with Small Ring Magnet .

AS5600 is a programmable 12-bit high-resolution contactless magnetic rotary position sensor. AS5600 can work as a magnetic potentiometer or a magnetic encoder with excellent reliability and durability.

Compared with the traditional potentiometer/encoder, AS5600 has significant advantages: high precision, non-contact, no limits on rotation angle. All those advantages making it suitable for non-contact angle measurement applications, such as the robot arm, tripod head, motor closed-loop control, machine tool axis positioning.

Features

• Non-contact, no rotation angle limitation
• 12-bit high-resolution, 4096 positions per round
• I2C (digital) or PWM (Analog) Output

Working Principle

AS5600 is based on the Hall Effect (the chip contain 4 hall effect sensor arranged in a circle). The build-in Hall sensor can detect changes in the direction of the magnetic field. The magnetic field direction information is amplified by the amplifier, with the help of the build-in 12-bit A/D, the AS5600 module can output 4096 positions per round.

The output is selectable, you can either use the I2C interface to output the RAW data or output the PWM wave/Analog wave via the OUT pin. Meanwhile, the maximum angle is also programmable, you can set the maximum angle from 18 to 360, which means that the measured angular accuracy is up to 18/4096 =0.005 degree resolution.
