This rear axle speed sensor is designed for karting applications. Add the Magnetic Axle Collar (Part No. MC-175, sold separately) to trigger the sensor. The 3-pin "712" (screw-in) connector works with MyChron3 Plus, Gold, Extreme, and GPS Dash karting dashes.
The front of the sensor has M10 threads for easy mounting in a bracket you supply. No bracket is supplied due to the variety of installations. A simple sheet metal bracket is all that is required. The sensor should be positioned 8mm to 15mm (5/16" to 9/16") from the collar; the optimum distance being 10mm (3/8"). Cable measures 67" long.
