Hall Effect Threaded Body Crankshaft Position Sensor


In stock

SKU: HallThreaded-K Categories: , Brand:



Red anodized aluminum hall effect crankshaft or camshaft position sensor.  Threads are M12 and mounting nuts are included.  Runs off 5 to 24 volts, and gives a nice square wave so there’s no variable voltage issues. Has a 1 meter long, 3 wire pigtail. Here’s what the wires do:

Brown – Supply voltage; connect to either VREF for 5 volt operation or 12 volt switched power.

Black – Output signal. On a MegaSquirt, connects to pin 24. We just set our MegaSquirt up for the VR conditioner and it works great. V3.0 MicroSquirts can also do this, but older MicroSquirts will need to use the Hall effect input. Note that this one requires a pull up resistor. This tees into both the supply voltage and the output signal wire. Use a 1K resistor (now included with the package) when powering it with 5 volts or a 2.4K resistor when powering it with 12 volts.

Blue – Ground.

Be careful if you are switching to this from a previous version of our sensor. The wire colors do not match, and this version requires a pull up resistor.

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

  • Yes, you must add a voltage pullup; this sensor does not have a pullup built in.

How does this sensor differ from the previous threaded Hall effect sensor you sold?

  • This one is made by a different manufacturer. While the size is the same, this one has a much larger temperature range and does not require quite so close a sensor gap. It also requires a pull up resistor, as noted above.

The sensor came with a resistor - what are the specs on the resistor?

  • We now supply them with a 1K ohm, 1/4 watt resistor for use with 5 volt supply voltage.

    Our supplier recommends using a 2.4K ohm, 1/4 watt resistor if using a 12 volt pull up.

    Set the V3.0 board up for the VR input circuit - it works great with Hall effect sensors too.
