Alnico alloys make strong permanent magnets, and can be magnetized to produce strong magnetic fields. Of the more commonly available magnets, only rare-earth magnets such as neodymium and samarium-cobalt are stronger. Alnico magnets produce magnetic field strength at their poles as high as 1500 gauss (0.15 tesla), or about 3000 times the strength of Earth’s magnetic field. Some brands of alnico are isotropic and can be efficiently magnetized in any direction. Other types, such as alnico 5 and alnico 8, are anisotropic, with each having a preferred direction of magnetization, or orientation. Anisotropic alloys generally have greater magnetic capacity in a preferred orientation than isotropic types. Alnico’s remanence (Br) may exceed 12,000 G (1.2 T)[clarification needed], its coercivity (Hc) can be up to 1000 oersted (80 kA/m), its energy product ((BH)max) can be up to 5.5 MG·Oe (44 T·A/m). This means alnico can produce a strong magnetic flux in closed magnetic circuit, but has relatively small resistance against demagnetization.

Reed sensors when paired with permanent magnets present an ideal method of sensing and detecting movement, proximity, metal detection, and liquid level and flow measurement. Reed sensors open and close their reed switch contacts in the presence of a magnetic field. Typically a permanent magnet is the moving member in the magnetic system. This can be a piston, a float, a rotating disk, and much more. our Magnetic Interaction animations which demonstrates how a reed sensor operates with a magnet used in various movements and positions, affecting the magnetic field array. Reed sensors come in hundreds of different sizes and shapes to meet a multitude of different application requirements.  MPCO specializes in customizing designs to specific customer needs for a wide range of applications.
