    This invention relates to a technique for measuring rotational speeds with conversion to pulse frequency and can be used in vehicles. Pulse sensors are known on different physical principles for converting rotational speed to pulse frequency lj. The closest to the invention in its technical essence is a pulse sensor containing a magnetic system made in the form of two N-shaped magnetic cores, signal windings located on the crossbars of the magnetic cores, and permanent magnets between the crossbars, which form different polarity with the ends of the magnetic core. Pulse sensor are its structural complexity and increased dimensions. The purpose of the invention is to simplify the design. And reduce the size. shaped magnetic one of its poles from the side opposite the gear disk. Figure 1 shows the design of the sensor circuit; Figures 2 to 4 of the permanent magnet magnetic flux paths at different positions of the toothed disk of the sensor. The sensor (Fig. 1) contains a toothed disk 1, a permanent magnet 2 and an H-shaped magnetic circuit with legs 3 and 4 and a jumper 5. A signal coil 6 is located on the jumper 5. mounting flanges 8 and 9 and output terminals 10 and 11. The permanent magnet is located between the ends of the legs 3 and 4 opposite the toothed modulating disk 1 and is oriented so that the ends of the legs facing the toothed disk have the same polarity. The distance between the ends is chosen larger than the gap between the two teeth of the disk, but smaller than the gap between the three teeth. The principle of the vehicle wheel speed sensor is to modulate the magnetic conductivity of the air gaps between the disk and the H-shaped magnetic core. A change in the magnetic conductivity of the gaps (Figures 2-4) causes the flow of a variable magnetic flux in the jumper 5 and induction of voltage in the coil 6 on the jumper. Due to the H-shaped design of the magnetic circuit and the chosen orientation and location of the permanent magnet, the sensor wheel of the vehicle has a covered design and small dimensions, which makes it easy to install it directly in the wheel of the vehicle.
