The MagAlpha MA102 magnetic sensor is an all-in-one solution designed to replace Hall switches for commutation in brushless DC motors and to provide absolute angle position.

Product Detail

The MagAlpha MA102 magnetic sensor is an all-in-one solution designed to replace Hall switches for commutation in brushless DC motors and to provide absolute angle position. Absolute position is provided in the form of an 8-bit direct digital angle on the SPI interface. 12-bit resolution UVW commutation signals are provided with emulation for 1 to 8 pole pair rotors.The MA102 detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft. Fast data acquisition and processing provide accurate angle measurement at speeds from 0 to 60,000 rpm.The MA102 supports a wide range of magnetic field strengths and spatial configurations. Both end-of-shaft and off-axis (side-shaft mounting) configurations are supported.
