DIYAutoTune.com has sold several Hall effect sensors. Select your sensor from the list below to see the specifications for your sensor.
Tabbed Mount Sensor
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. THIS WIRE MUST HAVE POWER WHENEVER THE IGNITION SWITCH IS IN THE “ON” AND “START” POSITIONS.
White – 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.
Black – Ground.
If you have the newest revision of our wiring harness, you can 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.
Specifications
Operating Voltage: 4.75 to 24 volts
Maximum Supply Voltages: +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
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.
New (Red Body) Threaded Sensor
Hall effect crankshaft or camshaft position sensor. This is a new version, distinguished by its red anodized aluminum housing. Threads are M12 and mounting nuts 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 or 12 volt switched power. THIS WIRE MUST HAVE POWER WHENEVER THE IGNITION SWITCH IS IN THE “ON” AND “START” POSITIONS.
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 teed between the VREF and signal wire to pull this up.
Blue – Ground.
Be careful if you are switching to this from a previous version of our sensor. The wire colors do not match and a pull up resistor is required for this version.
Specifications

Maximum Supply Voltages: +30 to -24 volts
Maximum Supply Current Required: 6 mA
Maximum Output Current Sinking: 20 mA
Output Type: Open Collector
Maximum Frequency: 15 kHz
Temperature Range: -40 to +125 degrees C
Nominal Air Gap: 1.5 mm
Thread Pitch: M12 x 1 mm
Overall Length: 65.5 mm (not including wires)
Package Material: Aluminum
Sensor Orientation: Not directional
Recommended tooth size is a rectangle measuring at least 2.5 mm x 6.35 mm, with a 5.0 mm tooth height.
Old (Silver Body) Threaded Sensor
Threads are M12 and mounting nuts included. 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. THIS WIRE MUST HAVE POWER WHENEVER THE IGNITION SWITCH IS IN THE “ON” AND “START” POSITIONS.
Blue – 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.
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 blue wires connect to the respective black and white wires inside the sheilded RPM input wire. Red to red, black to black, blue to white – pretty straightforward with only one mismatched color.
Specifications
Operating Voltage: 4.75 to 24 volts
Maximum Supply Voltages: +27 to -25 volts
Maximum Output Current: 20 mA
Maximum Frequency: 15 kHz
Temperature Range: -40 to +85 degrees C
Maximum Air Gap: 1.5 mm (We recommend setting the air gap smaller, usually as tight as possible)
- Note that our tabbed Hall effect sensor can use a wider air gap.
Thread Pitch: M12 x 1 mm
Threaded Length: 36 mm
Overall Length: 46 mm (not including wires)
Package Material: Stainless Steel
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.
