RF (Eddy Current) Speed Sensors

RF speed sensors offer low speed response, no drag, large air gaps and sensing characteristics which enable this type of speed sensor to sense non-ferrous metals like aluminum or nonmagnetic stainless steel in addition to ferrous metal. Unlike their VR counterparts, an RF speed sensor is not a passive device and requires coupling with a signal conditioners/preamplifier. These devices produce a digital square wave output versus the analog sine wave of the VR speed sensor.


In addition to our standard models, RF speed sensors are available in custom lengths, diameters, configurations, and mounting threads. Custom operating specifications (output options, etc.) are available, as well as options such as pigtail leads or NPT threading. See additional sensor customization options.
