AS5040 is a contact less magnetic rotary encoder for accurately measuring the angle of 360° in the whole amount. This is a system-on-chip, the integration of integrated Hall elements in a single package, the analog front end and digital data signal processing. When measuring the angle, simply equip a bipolar magnet that rotates above the center of the chip. The magnet can be installed above or below the IC. This absolute angle measurement method can indicate the angular position of the magnet instantly, with a resolution of 0.35°, which is 1024 positions per circle. The digitized data can be given in the form of a serial bit stream or PWM signal. In addition, it can also provide user-programmable incremental output, making this chip very suitable for replacing various optical encoder products. AS5040 has a built-in voltage regulator, allowing it to work at 3.3V or 5V power supply voltage. Generally this sensor module magnets are applied for Industrial applications, Non-contact rotation position detection, Robotics, Brushless DC motor commutation, Power tools, Automotive applications, Steering wheel position detection, Throttle Position detection, Transmission gearbox encoder, Headlight position control, Electric seat position indicator, Office equipment: printers, scanners, copiers, Replace optical encoder, Front panel rotary switch, Replace potentiometer
