Red anodized aluminum hall effect crankshaft or camshaft position sensor. Also suitable for use as a vehicle speed sensor (VSS). 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 an MS3Pro, this connects to the CKP+, CMP+, or digital frequency inputs. 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 sensor requires a pull up resistor. This tees into both the supply voltage and the output signal wire. Use a 1K resistor when powering it with 5 volts (not included) 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.
