Hall Effect Crankshaft Position Sensor



Hall effect crankshaft or camshaft position sensor. We’ve tested this with our 6.75″ and 8.25″ trigger wheels. We were able to get a rock solid reading at over 19,200 RPM, which is as fast as our test rig could spin the trigger wheel. Runs off 5 to 24 volts, and gives a nice square wave so there’s no variable voltage issues. Has a 12 inch long, 3 wire pigtail. Here’s what the wires do:

  • Red – Supply voltage; connect to either VREF or 12 volt switched power.
  • White – Output signal. On a MegaSquirt V3.0 or V3.57, connects to pin 24. We just set our MegaSquirt up for the VR conditioner and it works great. V3.0 MicroSquirts can also accept this signal over their VR conditioner input, but older MicroSquirts will need to use the Hall effect input.
  • Black – Ground.

If you have the newest revision of our wiring harness, you can just tee the red wire on the sensor into the red harness wire, and the black and white wires connect to the respective black and white wires inside the shielded RPM input wire. Red to red, black to black, white to white – simple and easy to remember.


  • Operating voltage: 4.75 to 24 volts
  • Maximum overvoltage and reverse voltage: +27 to -25 volts
  • Maximum output current: 20 mA
  • Maximum frequency: 15 kHz
  • Temperature range: -40 to +125 degrees C
  • Maximum air gap: 5 mm
    • Note that this is an absolute maximum. For most trigger wheels, operation is most reliable at a 1.0 to 1.5 mm air gap.
  • The trigger wheel must be at least 2 mm wide, the teeth and gaps at least 2 mm wide, and the gaps at least 2 mm deep. Hall effect sensor

    Will I need to add a pullup to use this sensor?

    • No, this sensor has a voltage pullup already on the signal wire.

      We carry this sensor for use with the MegaSquirt family of ECUs. We have not confirmed if it will work with an EDIS module or OEM engine management. I would typically recommend using OEM sensors with OEM engine management; the sensors and controllers were often designed as a matched pair.

      Yes, we picked this size especially to fit common large-diameter Chevy dampers.

      The question on the sensor location is one I've seen fairly often. The sensor needs to be installed so it reads the edge of the wheel, perpendicular to the crank center line, instead of reading the face of the wheel, parallel to the crank center line.

      It depends on what MegaSquirt version you are using. The MSPNP is not set up for a Hall effect sensor; some other variants can use this sensor no problem.

      We have not tested it, but the crank trigger on these cars appears to have the right dimensions. It is likely you will need to fabricate a separate bracket.

      Yes, it is built in.

      The teeth need to be centered over the small black circle on the end of this sensor for best results. I can't promise you will be able to get a reading if the teeth are not lined up as designed.

      As long as the MegaSquirt is configured for the right input type and the trigger wheel teeth match the minimum recommended dimensions or larger (2.0 mm minimum trigger width, 2.0 mm minimum tooth / notch depth, and 2.0 mm minimum tooth / notch width measured along the diameter of the trigger wheel). Please measure your trigger wheel before ordering.
