OREANDA-NEWS. MultiDimension Technology Co., Ltd. (MDT) announced a new Tunneling Magnetoresistance (TMR) magnetic angle sensor TMR3004. Featuring a large operating range over 1000 Oe, TMR3004 is a general-purpose magnetic angle sensor that is ideally suited for a variety of industrial and consumer sensor applications under wide-ranging operating conditions, including rotary encoders, speed sensors, contactless potentiometers, motor controllers, and utility meters.

"MDT's TMR3004 is the first 360-degree magnetic angle sensor on the market that features an operating range over 1000 Oe. A wider operating range implies higher immunity to external field disturbance, much relaxed tolerance to air-gap and mechanical mounting positions, and greater versatility for use in many different types of applications. Designed with MDT's unique TMR technology and intellectual property, the TMR300X magnetic angle sensors feature 360-degree angle measurement, high-amplitude robust output signals, low power consumption, large air-gap tolerance, and they provide a simple solution to integrate with analog or digital circuitry," said Dr. James G. Deak, CTO of MultiDimension Technology.

Key Features of TMR3004

360-degree measurement with dual-axis SINE/COSINE outputs

Large output signal above 90 percent of supply voltage, eliminating the need for amplification

Large operating range from 150 to 1100 Oe, permitting large air-gap tolerance, greater versatility and choice of implementations for many applications

High precision in 1.5 degree analog angular position error and can be enhanced by digital calibration

Small LGA package

MDT's TMR sensor technology combines the key benefits of existing magnetic sensor technologies such as AMR (Anisotropic Magnetoresistance), GMR (Giant Magnetoresistance), and Hall Effect, while overcoming their limitations with high signal sensitivity, large air-gap tolerance, reduced design complexity for 360-degree measurement, and excellent thermal stability.

MDT is the first volume supplier of TMR sensors with multiple product portfolios. In addition to the TMR angle sensors, MDT offers TMR magnetic switches, TMR linear magnetic field sensors, TMR gear tooth sensors, and TMR magnetic image sensors. MDT also provides comprehensive service options including custom designs, foundry service, and IP licensing for TMR/GMR/AMR sensors.
