AKM releases a differential output type encoder element of high-resolution that supports m=0.3 gears

2022/05/16

Description

Asahi Kasei Microdevices Corporation (AKM) has released the MS0031, a differential output type encoder semiconductor magnetoresistive element (SMRE) of high-resolution that is ideal for use with gear wheels of module m=0.3. 

The MS0031 delivers an encoder of more than 20-bit through electrical interpolation because the signal waveform detected from gears are similar to sine or cosine waves.

The MS0060, a single output type suited for use with gears of module m=0.6, is also now available.

Features

MS0031: Differential output products that support module m=0.3

The introduction of a differential output type product that supports m=0.3 gears has expanded the lineup of AKM's SMRE.

By applying differential output, a difference is formed from Phase A and Phase B, thereby eliminating in-phase noise. In addition, twice the output amplitude is obtained. These factors contribute to the high accuracy and high resolution of the magnetic encoder.

Applications

  • Motor control
    • Industrial robots
    • Machine tools
