Variable reluctance (VR) linear position sensors and switches are noncontact devices which measure the position and speed of moving metal components. The sensor head of these devices essentially ...

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 ...

The collapse of magnetic field due to the interruption by a ferrous gear tooth provides an analog signal output (sine wave) that does not require an outside power source. Variable reluctance sensor or ...

The DNA-VR-608 is an 8-channel, variable reluctance sensor interface and frequency out board. Each channel provides a fully differential input and is capable of monitoring VR output levels as high as ...
