Sensor is a kind of detection device, which is widely used in automobile industry, communication electronics, industrial automation and many other industries. It is composed of permanent magnet, detection gear and internal gear, forming a closed detection magnetic field circuit. When the detecting gear rotates with the axis of the sensor, the magnetic flux changes, and an induced voltage whose frequency changes proportionally with the magnetic flux is established at both ends of the coil. The magnetic flux fluctuates with the frequency f = speed (R / min) × teeth / 60 (Hz), and is output as the speed signal of the sensor. Modern everyday life would be very different without sensors and the operation of many of these sensors rely on magnetism. As products evolve, so have the range and specification of sensor magnets.

This product is not a toy and is not to be used by children. This product is to be used for scientific experiments or for industrial applications. This product contains strong Neodymium magnet(s) that can be harmful or fatal if swallowed. Strong Neodymium magnets are fragile, they are brittle and will break or chip if they hit a hard surface or are snagged together. Always use the utmost care when handling Neodymium magnets.
