Item Type: Rotational Speed Sensor <br>Material: Aluminium Alloy <br>Introduction: <br>The magnetic speed sensor indicates when ring gear teeth, or other ferrous projections, pass the tip of the sensor. <br>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. <br>Description: <br>The magnetic speed sensor is mounted in the ring gear case or flywheel bell housing of the engine. <br>The threaded hole for the speed sensor should be perpendicular to the center line of the crankshaft and centered over the ring gear teeth. <br>A spot face should be present to provide a flat surface on which to anchor the locknut. <br>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. <br>Any ferrous gear may be used as long as the frequency and amplitude of the resulting signal meet the speed control unit specifications <br>The wire leads should be twisted for their entire length from the magnetic speed sensor to the control unit. <br>The leads may need shielding if they are longer than 10 ft. (3 meter), or if external interference is present. <br>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. <br>Specification: <br>MSP6729 <br>3/8 - 24 UNF Threaded <br>2.5in Length with 6ft Shielded Cable <br>All are designed and tested to operate within a temperature range of -65℉ to 225℉ (-55℃ to 105℃) .<br>1、Application: Generator rotational speed sensor has stable performance, specially designed for magnetic generator pickup, perfect fit. <br>2、Thread Design: This magnetic generator speed sensor adopts threaded design, 3/8 24UNF 2A, easy to install, good accessory for generator. <br>3、Quick Response: Professional manufacturing, MSP6729 rotational speed sensor has excellent sensitivity and high reliability, practical to use. <br>4、Sturdy Aluminium Alloy: 24 UNF rotational speed sensor is made of high strength aluminium alloy material, lightweight, rustproof, durable to use. <br>5、Ideal Replacement: Strictly following the factory quality control, generator speed sensor is a great and direct replacement for the old or damaged one.1 x Sensor
