This sensor works by detecting metal protrusions on a wheel hub or drive shaft. It is suitable for vehicles that do not have an electronic speedometer output, or an existing speed sensor. The high quality water proof sensor is designed to handle the stress of be-ing mounted on a wheel hub or near the transmission system. It connects to the trip meter through a 2m long three wire cable. M12 thread, 55mm long.
