TMR Magnetic Sensors
TMR or Tunneling Magnetoresistance utilises a magnetic tunnelling junction element, comprising of a ferromagnetic free and pinned layers, separated by a dielectric spacer layer. The magnetism direction of both ferromagnetic layers can be switched; when parallel, electrons can make a quantum leap to tunnel through the spacer layer. At Rhopoint Components, we are proud to offer a full range of TMR sensors including analog and digital sensors, proximity, angle and rotation sensors and smart sensors for Arduino applications.
It is common to compare the TME devices to the traditional Hall effect sensors, as they are both compatible with the modern CMOS technology – the TMR, however, offers smaller package size (the RedRockTM series are some of the smallest magnetic sensors on the market), lower power consumption, 1000-times higher sensitivity and high thermal stability. If you are considering replacing your Hall effect sensors with the TMR sensors, please do not hesitate to contact us, our sales engineers are trained to provide support and help you find the best solution.
