AS5045B-ASST傳感器變送器的編碼器規(guī)格書(shū)PDF中文資料

General Description

The AS5045B is a contact less magnetic position sensor for accurate angular measurement over a full turn of 360 degrees. 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 magnet can be placed above or below the IC.

Key Features

??Contact less high resolution rotary position sensor over a full turn of 360 degrees
