MDT Launches Global Sales of TMR4101 Micron-Precision Magnetic Scale Sensor at Sensor+Test 2024

The TMR4101 magnetic scale sensor is designed for consumer electronics and industrial applications, including camera autofocus and zoom, micron-level displacement measurement, linear and angular position measurement, and magnetic encoders. It operates in conjunction with a multi-pole magnetic scale with a 0.4mm magnetic pole pitch. As the sensor moves along the magnetic scale, its two push-pull TMR half-bridge structures output sine and cosine signals with a 90° phase shift. The signal period corresponds to the 0.8mm length of a pair of adjacent north and south poles.

Featuring excellent signal sensitivity and low noise thanks to MDT's unique TMR technology, the TMR4101's differential gradiometric sensor design provides high immunity to stray field interference. The TMR4101 supports temperature-compensated precision measurement capabilities that effectively negate temperature impacts on measurement accuracy by calculating the position through both sine and cosine signals with identical temperature characteristics. MDT also offers high-precision 0.4mm pole-pitch magnetic scales to complement the TMR4101, with the length and width of the magnetic scale customizable according to application requirements. In typical applications, the combination of the TMR4101 and magnetic scale can achieve a repeatability precision within +/-1 micron.

Key Features of TMR4101:

The TMR4101 sensor and corresponding magnetic scales are available for order from Digi-key and MDT's online store at www.tmr-sensors.com. For volume pricing, delivery, and technical inquiries, please contact MDT at [email protected] or visit their booth 1-239 at Sensor+Test 2024 in Nuremberg, Germany, from June 11-13.
