Engine Rotation Speed SensorProduct Quick Information: Electromagnetic induction principle;Good anti-interference performance;Dust & fog proof;ISO9001: 2008 certification;Made to order service offered. Product Detailed Information: Product Brief Introduction: Engine rotation speed sensor realizes the speed detecting purpose through electromagnetic induction. It offers rotating speed signal and crankshaft position signal to the ECU through counting the tooth number on the flywheel. And it possesses characteristics of strong output signal, no amplification needed, good anti-interference performance, no external power needed, being used in severe environment, such as smoke fog, oil gas, water vapor or coal gas environment.Product Technical Data:Operational voltage: 12V and 24V (universal);Output voltage: >=3.1V;Tow-blade shape connector plug resistivity: 1050Ω 1250Ω;Operational temperature: -20°C l20°C;Lead wire length: Maxi 500mm, spiral spring line.Installation:Normally installing on the housing of the flywheel;Adjusting the gap between the sensor and the gear wheel within 0.3---1.0mm;Using the device in lower than 25°C high magnetic field;Properly adjusting the gap when the jitter margin too large to avoiding damage.Product Schematic Diagram:The information and technical data above are just for your reference, and only specially applicable to the product of this model No..
