General Features
5/8 - 18 UNF Threaded Magnetic Pickup Automotive Speed Sensor MSP677 indicates when ring gear teeth, or other ferrous projections,pass the tip of the sensor. Electrical impulses are induced within the coil and sent to the speed control unit. The signal from the magnetic speed Sensor, teeth per second(HZ), is directly proportional to engine speed.
*The magnetic speed sensor indicates when ring gear teeth, or other ferrous projections, pass the tip of the sensor.
*Electrical impulses are induced within the coil and sent to the speed control unit.
*The signal from the magnetic speed sensor, teeth per second(HZ), is directly proportional to engine speed. The magnetic speed sensor is mounted in the ring gear case or fly wheel bell housing of the engine.
*The threaded hole for the speed sensor should be perpendicular to the center line of the crankshaft and centered over the ring gear teeth.
*A spot face should be present to provide a flat surface on which to anchor the lock nut.
*With the engine stopped, screw the speed sensor in until it touches a gear tooth, then back it out 0.75 of a turn and secure it with the lock nut.
*Any ferrous gear may be used as long as the frequency and amplitude of the resulting signal meet the speed control unit specifications.
*The wire leads should be twisted for their entire length from the magnetic speed sensor to the control unit.
*The leads may need shielding if they are longer than 10 ft(3m), or if external interference present.
Do not connect either of the speed sensor leads to anything but the speed control unit used. The shield should not be connected at the speed sensor end.
