    Tips: Types of magnetic proximity sensor

    • Hall magnetic proximity sensor
      The Hall proximity sensor has the characteristics of no electric shock, low power consumption, long service life and high response frequency. The interior is integrated with epoxy resin, so it can work reliably in various harsh environments. Hall proximity switches can be used in position switches, pressure switches, odometers, etc., as a new type of electrical accessories.
      Hall proximity switches are suitable for position determination of pneumatic, hydraulic, cylinder and piston pumps, and can also be used as limit switches. When the magnetic target approaches, the Hall effect is generated, and the output switching signal is amplified. Compared with inductive sensors, it has the following advantages: it can be installed in metal, can be installed closely side by side, and can detect through metal. The disadvantage is: the distance is affected by the strength of the magnetic field and the approaching direction of the detection body, there may be two working points, and iron materials are not allowed to be used for fixing.
    • Magnetic reed proximity sensor
      The internal structure of a magnetic reed switch is similar to what is commonly referred to as a reed relay. It is a contact sensor consisting of two high-permeability alloy reeds sealed in a glass tube filled with an inert gas. A certain overlap and proper gap are maintained between the two reeds, the ends are gold-plated as contacts, and the leads are welded outside the tube. When the magnetic field strength at the position of the reed switch is large enough to make the magnetic attraction generated by the magnetization of the contact spring pieces overcome the elastic force of the spring pieces, the two spring pieces attract each other to make the contacts conduct. When the magnetic field is weakened to a certain extent, it is released by the elastic force of the spring sheet itself. Small size, small inertia, and fast action are the outstanding features of magnetic reed switches.
