Introduction: *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. Description: *The magnetic speed sensor is mounted in the ring gear case or flywheel bell housing of the engine. *The threaded hole for the speed sensor should be perpendicular to the centerline 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 locknut. *With the engine stopped, screw the speed senor in until it touches a gear tooth, then back it out 3/4 of a turn and secure it with the locknut. *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 is present.

• Accurate RPM Measurement: Detects ferrous gear teeth movement, generating electrical signals proportional to engine speed (Hz) for precise speed control in generators or engines.
• Simple Installation: Mounts perpendicular to the crankshaft; screw in until contacting gear teeth, then back out 3/4 turn and lock with nut for optimal signal alignment.
• Versatile Compatibility: Compatible with any ferrous gear meeting frequency/amplitude requirements of speed control units, suitable for generators and industrial engines.
• Robust Construction: Durable 5/8-18 UNF-2A threaded design (6.125" overall length, 37/64" drill size) ensures reliability in harsh environments.
• Signal Protection: Twisted leads reduce interference; shielding recommended for cables over 10 ft (3m) to maintain signal integrity. Do not connect leads to non-specified devices.
