/PRNewswire/ --

MultiDimension Technology Co., Ltd. (MDT) announced the world's first

Tunneling Magnetoresistance (TMR) gear tooth sensors for industrial motion

sensing applications that measure position and speed of gear teeth, cams,

linear and rotary magnetic encoders, and linear magnetic scales.

The new MMG44DG TMR magnetic gear tooth sensors are designed and

manufactured with MDT's unique TMR sensor technology and intellectual

property. They feature very high sensitivity for small-pitch gear tooth detection,

high-amplitude output signals that are resistant to magnetic field interference,

large air-gap tolerance, and low power. They offer very high resolution for

detecting small changes in magnetic field by gear teeth, magnetic strips, linear

magnetic scales, and other ferrous materials.

"MDT's TMR magnetic gear tooth sensors are the first-of-a-kind on the market,

and they bring many unique benefits of TMR sensor technology to our

customers, with small-pitch gear tooth detection, robust signals, and larger air-

gap," said Dr. Song Xue, Chairman and CEO of MultiDimension Technology. "We

are fully committed to deliver the best value to our customers with multiple

service options, including TMR sensor wafers, TMR sensor chips, custom

designed packages, custom sensor modules, and application solutions."

MDT's TMR sensor technology realizes the key benefits of existing magnetic

sensor technologies including Hall Effect, AMR (Anisotropic Magnetoresistance)

and GMR (Giant Magnetoresistance), while adding high sensitivity, large signal

output, and low power inherent in TMR technology. MDT offers all advantages

of TMR to the commercial sensor market in a growing product portfolio,

including TMR magnetic field sensors, TMR magnetic angle sensors, TMR

magnetic switches, and the new TMR magnetic gear tooth sensors.

Key Features

Small-pitch gear tooth detection at 0.5/1.0/1.5mm

Direction and phase measurement with SINE/COSINE outputs

High sensitivity allowing large air-gap tolerance for easy installation

High tolerance to magnetic field interference

Wide dynamic range and linear operating range
