MDT Launches TMR4101 Magnetic Scale Sensor for Precision Measurement

MultiDimension Technology Co., Ltd. (MDT) has unveiled the TMR4101 magnetic scale sensor, a cutting-edge device that offers precise linear displacement measurement with remarkable temperature stability and resistance to stray field interference. This sensor is specifically designed for both consumer and industrial applications, operating in conjunction with a 0.4mm-pitch magnetic scale to deliver micron-level precision.

The TMR4101 sensor employs push-pull TMR half-bridge structures to produce sine and cosine signals with a 90° phase shift as it moves along the magnetic scale. Its differential gradiometric sensor design ensures high sensitivity and low noise, thanks to MDT's advanced TMR technology, resulting in superior immunity to stray field interference.

One of the key features of the TMR4101 sensor is its temperature-compensated precision measurement capabilities, which enable accurate position calculation by leveraging the identical temperature characteristics of sine and cosine signals. Additionally, MDT offers customizable 0.4mm pole-pitch magnetic scales to complement the TMR4101, allowing for precise customization based on specific application requirements.

When used together, the TMR4101 sensor and magnetic scale can achieve repeatability precision within +/-1 micron, making them ideal for applications such as camera autofocus, micron-level displacement measurement, and magnetic encoders. These innovative products are readily available for purchase through Digi-Key and MDT's online store, with volume pricing and technical inquiries directed to MDT's dedicated sales team.

MDT, a renowned manufacturer of magnetic sensors specializing in Tunneling Magnetoresistance (TMR) technology, was established in 2010 and has quickly become a prominent player in the industry. With a strong commitment to innovation and customer satisfaction, MDT continues to deliver high-performance, cost-effective solutions to address a wide range of application needs.

The introduction of the TMR4101 magnetic scale sensor by MDT marks a significant advancement in linear displacement measurement technology. With its exceptional precision, temperature stability, and resistance to interference, this sensor opens up new possibilities for applications requiring high accuracy and reliability. As MDT continues to push the boundaries of magnetic sensor technology, customers can expect even more innovative solutions tailored to meet their evolving needs.
