MKA 16101 Reed Sensor 16MM
Reed MKA16101 normally open reed switch magnetic switch 16MM length
(Reed Switch), also known as reed or reed switch, is a special kind of magnetic switch, and is the main component reed relays and proximity switches.
The working principle of : Dry reed pipe principle is very simple, and overlap between the two endpoints can magnetization of reeds, sealed in a glass tube, the distance of two reed space only about a few microns, the glass tube filling with high purity of inert gas, before operation, two pieces of reed did not contact, plus a magnetic field to make two pieces of reed endpoint location near produce different polarity, the results of two different polarity reed will be attracted to each other and closed. According to this technology can be made very small volume switch components, and switching speed is very fast, and has very good reliability. Permanent magnet orientation and direction to determine when and how much time switch on and off.
So form a switch: when permanent magnet near the dry reed pipe or around the dry reed pipe coil electricity make reed magnetization of a magnetic field, reed contact part will be attracted by magnetic force, when the appeal is greater than the reed elastic, normally open contacts will suck us; When magnetic force to reduce to a certain degree, contact opens in the leaf spring
Good electrical connection is through the contact of two overlapping parts coated with a thick layer of nonmagnetic metal, low resistivity of silver than the corrosion resistance of gold is more suitable for as a coating material . There are also using mercury wetted tube, wet spring tube contact must be installed in pairs. Two spring wire made of nickel/iron, nickel and iron alloy of nickel (52%). Affected by magnetic field of magnetic reed fuses must be ferromagnetic.Three of the most popular material properties, easy annealing ferromagnetic: iron, cobalt and nickel. Two is the tip of the reed contacts or sputtering plating rhodium, ruthenium or iridium.
Used for glass tube outer packaging, its temperature coefficient of expansion (TCE) exactly match NiFe alloy. At both ends of the glass tube is heated and glass melting, form a gas-tight seal on both ends of the cover.In the process of glass sealing glass cavity is usually filled with inert gas (usually nitrogen) or cavity, may create a vacuum, vacuum. The vacuum is usually support high voltage switch (more than 1000 volts)
