MDT Releases TMR Switch Sensors for Industrial Proximity Sensing, Pneumatic Cylinder Sensing and Liquid Level Sensing

Advanced TMR Technology Realizes Small Hysteresis, Ultra-compact Form Factor, Ultra-low Power, and Excellent Temperature Stability for High-performance Industrial Sensor Applications

SAN JOSE, Calif. and ZHANGJIAGANG, China, – MultiDimension Technology Co., Ltd. (MDT), a leading supplier of magnetic sensors specializing in Tunneling Magnetoresistive sensors (TMR sensors), will release a series of ultra-low power, small hysteresis TMR magnetic switch sensors, TMR1340/TMR1341/TMR1343/TMR1345, featuring a switching point from 14 Gauss to 72 Gauss with small hysteresis, ultra-low power at 1.5microAmperes in high-speed operation, with open-drain output, and an ultra-compact 2x1.5mm LGA package. They are an ideal choice for industrial proximity switches, pneumatic cylinder switches, and liquid level switches that require precise measurement of position and displacement, excellent temperature stability, and versatility to adapt to different types of magnets and stroke lengths.

"MDT's new TMR134X series enriches our existing magnetic switch sensor product line with new solutions for high-end industrial applications that can operate in harsh environments without sacrificing performance, power, and size advantages. Backed by our strong IP portfolio and advanced manufacturing facilities, MDT will continue developing innovative TMR sensor products to satisfy broad application requirements, including high sensitivity, large dynamic range, small hysteresis, ultra-low power, high-speed, and outstanding temperature performance, which are the unique benefits of our patented TMR sensor technology that are difficult to realize using other magnetic sensing technologies available on the market." said Dr. Song Xue, Chairman and CEO of MultiDimension Technology.
