AS5030传感器变送器的编码器规格书PDF中文资料

General Description

The AS5030 is a contactless magnetic rotary encoder for accurate angular measurement over a full turn of 360°.

It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device.

To measure the angle, only a simple two-pole magnet, rotating over the center of the chip is required.

The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 8 bit = 256 positions per revolution. This digital data is available as a serial bit stream and as a PWM signal.

In addition to the angle information, the strength of the magnetic field is also available as a 6-bit code.

Key Features

■360° contactless angular position encoding

■Two digital 8-bit absolute outputs:

- Serial interface

- Pulse width modulated (PWM) output

■User programmable zero position

■Direct measurement of magnetic field strength allows exact determination of vertical magnet distance

■Serial read-out of multiple interconnected AS5030 devices using daisy chain mode

■Wide magnetic field input range: 20 ~ 80mT

■Wide temperature range: -40°C to +125°C

■Small Pb-free package: TSSOP 16

Applications

The AS5030 is suitable for Contactless rotary position sensing, Rotary switches (human machine interface), AC/DC motor position control, Robotics and Encoder for battery operated equipment.
