An easy-to-fabricate, full circle range (0°–360°), planar coil-based variable reluctance (VR) angle transducer with enhanced linearity is presented in this article. The proposed sensor system aims to ...

Variable Reluctance Sensors The discoveries of Michael Faraday led to the development of the variable reluctance sensor, which uses a wire-wrapped magnet to detect changes in the magnetic field ...

Both variable reluctance (VR) and eddy current (EC) technologies provide contactless speed sensors based on interaction with a magnetic field. A variable reluctance sensor can be thought of as an ac ...

Control and protection circuits have relied on variable reluctance technology for years. With few components and no moving parts, the passive magnetic speed sensors can provide a signal from the ...

Communications protocols abound. The most useful are featured in components such as encoders to match application requirements.

VR sensors use variations in magnetic-field densities created by changes in reluctance within a magnetic circuit.

Variable-reluctance sensors are preferred for industrial and automotive environments, because they sustain mechanical vibration and operation to 300°C. In most applications, they sense a steel target ...
