Hall effect rotary speed sensor threaded mounted type M16/M18
Description
Yuli Intelligent YH-M series speed sensors are designed for sensing target’s movement such as rotational speed and position. With Hall-effect integrated circuit (IC) and a permanent magnet(samarium cobalt magnetic material) all sealed inside the rugged and probe-type package (Nickel plated copper/Brass),the IC detects alternation of magnet’s flux density when it approaches a ferrous metal target which is usually a gear wheel composed of Fe Co Ni materials(e.g. silicon steel ) or a permanent magnet. When the gear wheel rotates, the sensor will generate a square-wave pulse whose quantity is proportional to quantity of gear convex poles. This sensor is featured with outstanding performance of resistance to vibration and high operating temperature. With EMI radiated immunity protection built in, it can resist to great impulse of external current and voltage.
