Structural characteristics of photoelectric camshaft crankshaft sensor

The photoelectric crankshaft and camshaft crankshaft sensor is improved by the distributor, which is mainly composed of the signal plate (namely the signal rotor), the signal generator, the distributor, the sensor housing and the wiring harness plug.

The signal plate is the signal rotor of the sensor and is press-fitted on the sensor shaft. Two circles of light-transmitting holes, inside and outside, with evenly spaced arcs are made near the edge of the signal plate. Among them, the outer ring is made with 360 light-transmitting holes (slits), and the interval radian is 1. (The light-transmitting hole occupies 0.5. The light-shielding hole occupies 0.5.) It is used to generate the crankshaft angle and speed signal; the inner ring is made with 6 light-transmitting holes (rectangular holes L), and the interval radian is 60. , Used to generate the top dead center signal of each cylinder, one of the rectangular wide sides is slightly longer, used to generate the top dead center signal of cylinder 1.
