Sensors Midwest 2018: TMR Sensors Solve Numerous Challenges

(Coto Technology)

Although not exactly new, tunneling magnetoresistance (TMR) sensors are still somewhat in their sophomore stages in terms of mass deployment. Beginning as a variation of magnetoresistance sensors for industrial applications, TMR sensors consist of a magnetic multilayer film material.  Tunnel magnetoresistance (TMR) sensors rely on tunnel magnetoresistance, a magnetoresistive effect that takes place in a magnetic tunnel junction. The junction consists of two magnets with a thin insulator between them. Electrons pass back and forth between the magnets.


Sensors based on TMR have evolved past their initial usage in disk drives and other electromechanical devices. Proving quite versatile, TMR magnetic sensors are viable for use in a plethora of medical applications.


According to Tanios BouRamia, Product Line Manager – Sensors & Switches at Coto Technology, three of the most critical factors for electronic sensors used in next-gen devices are low power, sensitivity, and size. Tunneling magnetoresistance (TMR) is quickly becoming the preferred technology to address those requirements.


At Sensors Midwest, Rosemont, IL, October 16 to 17, Tanios BouRamia will be giving an insightful presentation titled “Using TMR Magnetic Sensors to Enable Measurement & Detection in Next-Gen Applications with Magnetic Proximity, Rotation, and Level Sensing Functions” on Tuesday October 16, 2018 from  4:00 pm to 4:50 pm. Tanios will present and explain the characteristics of TMR sensing technology to help attendees better understand the behavior and benefits of unipolar vs. bipolar vs. omnipolar TMR magnetic sensors regarding their functionality in proximity, liquid level, rotation sensing, and other applications. Attendees will discover how TMR magnetic sensors address ongoing issues, such as power consumption and actuation distance, with next generation measurement and detection device requirements when monitoring fluid flow, liquid level, proximity, anti-tampering, or enabling “wake-up.” Markets discussed will include industrial, white goods, appliance, consumer & security.


Tanios BouRamia is Coto Technology’s Product Line Manager for Sensors & Switches. He has been with Coto Technology for more than seven years and is heavily involved with product development and documentation, associated business development and strategic marketing, and monitoring of supply chain and regulatory environments.


Tanios holds an MBA in Strategic Design from Philadelphia University’s Kanbar College of Design, Engineering, and Commerce and B.S. Degrees in Electrical Engineering and Biomedical Engineering, earned at the University of Rhode Island’s College of Engineering.
