FuelTech 7994 VR-Hall Converter

V R/Hall Converter
The VR/HALL converter was designed to read an analog VR signal and transform it to a digital signal (Hall). Recommended when using VR speed sensors (found in most ABS systems) or when using VR fuel flow meters, for example.

Important Notes

  • Do not share 12V between the converter and coils or actuators.
  • When connecting the VR/Hall converter to the VR sensor, it might be necessary to swap the wires, since VR sensors have specific pinout to read properly.
  • Some ABS sensors are not compatible with the VR/Hall converter. Sensor GAP can affect VR sensor reading, in most of the cases a gap close to 0.030in.

Specifications

  • Minimum signal peak voltage : 0,5V
  • Maximum signal peak voltage: 150V
  • Maximum frequency: 15000Hz (15kHz)
