AS5040-ASST AS5040 Programmable Contactless Magnetic Rotary Encoder Sensor Module

Product introduction The AS5040 is a contactless magnetic rotary encoder for accurate measurement of angles up to 360° The product is a system on a chip that incorporates integrated Hall components an analog front end and data signal processing capabilities in a single package To measure angles simply equip a bipolar magnet that rotates over the center of the chip The magnet can be mounted above or below the IC This absolute Angle measurement provides an instant indication of the angular position of the magnet with a resolution of 0 35° or 1 024 positions per turn Digitized data can be given in the form of a serial bit stream or a PWM signal In addition it can also provide user programmable incremental output which makes the chip suitable for replacing various optical encoder products The AS5040 has a built in volt age regulator that allows it to operate at either 3 3V or 5V supply voltage Product features Complete system on a chip Flexible system solution that simultaneously provide absolute serial output PWM output and incremental output Ideal for harsh applications due to the contactless detection method Can withstand magnet position deviation and air gap variation No temperature compensation is required No calibration requiredThe main features Contactless high resolution rotational position coding over the entire 360° rangeTwo kinds of digital 1 O bit absolute value output Serial interface output as well Pulse width modulation PWM outputThree increment
