TDK's complete range of sensors, marketed under the product brands TDK, EPCOS, InvenSense and Micronas includes temperature sensors, pressure sensors, angle sensors, current sensors. Especially magnetic-field sensors based on Hall-sensor or TMR technology can be found in almost any machine that needs to measure position, linear or rotational movement or even current.
Precise current sensors are indispensable for intelligent power in electric vehicles and smart grids. Temperature sensors and sensor systems are used to regulate the temperature of refrigerators and air-conditioning systems or to measure the temperature of operating fluids in motor vehicles, for example. Pressure sensors are used in a wide range of applications in automotive and industrial electronics, medical engineering, and environmental technology. TMR (Tunnel Magneto Resistance) angle sensors offer high output, high resistance to noise and have excellent angle accuracy.
Hall-effect sensors are commonly employed for a wide range of automotive applications, e.g. powertrain, chassis and body systems, or safety and security applications. They comprise on one hand simple Hall switches to detect a position, and on the other hand quite complex Hall-effect sensors for the measurement of distances, angles or rotational movement.
