Three types of camshaft crankshaft sensor(2)

Hall-effect speed sensor and camshaft crankshaft sensor are a signal generator that utilizes the Hall effect. The Hall signal generator is installed in the distributor, coaxial with the distributor head, and is integrally fixed on the distributor plate by a packaged Hall chip and a permanent magnet. The number of notches on the trigger impeller is the same as the number of engine cylinders. When the blade on the trigger impeller enters between the permanent magnet and the Hall element, the magnetic field of the Hall trigger is bypassed by the blade. At this time, no Hall voltage is generated, and the sensor has no output signal; when the gap on the trigger impeller enters the permanent magnet When it is between the Hall element and the Hall element, the lines of magnetic force enter the Hall element, the Hall voltage rises, and the sensor outputs a voltage signal.
