Description

Asahi Kasei Microdevices Corporation, (AKM), has released the MS0083, a differential output semiconductor magnetoresistive element, (SMRE), for module, “m“ = 0.8 gear wheels, expanding the lineup of AKM’s SMRE.
The MS0083 is optimized for a gear wheel sized in the range from Φ60 to 100 mm.  It eliminates in-phase noise with differential output signals of A+/A- and B+/B-.  The MS0083 achieves high resolution rotation angle detection exceeding 20-bit from electronic interpolation, achieving top-level performance among magnetoresistive elements*.  This is due to its stunning temperature characteristics while having extremely small variability among individual devices.
* According to AKM’s research as of September 2018.

SMRE
Output voltage is nearly ideal sine/cosine wave = Electric interpolation is possible.

Features

● A+/A-, B+/B- Differential Output

Since phase A and B are output with phase differences, it is possible to eliminate in-phase noise by taking the difference and contributing to high precision and high resolution of the magnetic encoder because the output amplitude can be obtained twice.


● Optimized for a Specific Type of Gear

The MS0083 is designed to have the smallest system offset voltage when it is used with a gear that has m=0.8 and 64 to 128 gear teeth, (Φ60 to 100mm).  Therefore, it realizes high precision and high-resolution magnetic encoding with a gear of this size.
*m is standard value to express the size of gear wheel and calculated as, m=(Pitch Circle Diameter)/(No. of Tooth).
