MultiDimension Technology (MDT) has launched an advanced Tunneling Magnetoresistance (TMR) gear tooth sensors that are effective for use in industrial motion sensing applications that involve measuring the position and speed of cams, gear teeth, linear magnetic scales and linear and rotary magnetic encoders.
Based on its unique TMR sensor technology and intellectual property, MDT developed the new MMG44DG TMR magnetic gear tooth sensors. It ensures maximum sensitivity for small-pitch gear tooth detection, magnetic field interference-resistant high-amplitude output signals, low power, and large air-gap tolerance. In addition, the sensor’s high resolution enables the detection of even slight variations in magnetic field by gear teeth, linear magnetic scales, other ferrous materials, and magnetic strips.
MDT's TMR sensor technology incorporates the advantages of existing magnetic sensor technologies such as Hall Effect, GMR (Giant Magnetoresistance), and AMR (Anisotropic Magnetoresistance) and supplements TMR technology with low power inherent, high sensitivity, and large signal output. MDT presents the commercial sensor market with this highly-featured TMR. TMR line of products include new TMR magnetic gear tooth sensors, TMR magnetic field sensors, TMR magnetic switches, and TMR magnetic angle sensors.
The major features of the highly versatile MMG44DG TMR magnetic gear tooth sensors are wide dynamic range and linear operating range, ensuring small-pitch gear tooth detection at 0.5/1.0/1.5 mm, and high tolerance to magnetic field interference. They provide exceptional temperature stability, direction and phase measurement with SINE/COSINE outputs, and include compact LGA packages. Their high sensitivity enables large air-gap tolerance for easy installation, feature reduced power consumption, and have versatile design, making them ideal for various position and speed sensing applications.
The MMG44DG TMR magnetic gear tooth sensors are currently being offered for sampling.
