Reed relay might not be a very familiar term for many of you out there. But, after reading this blog, you will get some understanding about what is reed relay. How does it work, and what makes it different from other relays. Reed relay is a small electromagnetic switching device. These are made by the placement of a coil around a single or multiple reed switches. Generally, the relay assembly is over-molded after that, or sealed for extra durability and handling. Working of the Reed Relays? If we are to talk about the working module of a reed relay. First, it is important to know, the different types of reed relay. Form A type is the most prominent and is in a normally open switch state. These relays are OPEN or OFF till there is a passage of current through the coil. The coil, that is electromagnetic, produces a magnetic field equivalent to a permanent magnet. Lastly, the subsequent magnetic field closes the contacts, which switches on the relay. On the other hand, when the current in the coil is not there, the switch turns off and the contacts are open once more. Form B relays which have N.C. biased contacts, which are held by a magnet. So, the relay is in a closed or off state until the energy is put back into the coil, opening the contacts. When there is no energy in the coil, it switches the relay off. Form C relay which has three contacts as opposed to two. They are generally open, usually closed, and common. The common contact will swipe from the closed to the open contact when it is switched on. When it is in OFF mode, the contact returns to its resting off position. So, these are also called a double throw switch. The last type Form E. This can exist in either the N.C. or N.O. state with no coil power making use of a biasing magnet. The contacts of the relay maintain their last position without the coil getting activated. For changing the contacts state, the magnetic field should be reversed. What Makes Reed Relay Unique? Reed relays are unique in many ways. One way in which it is unique is its Reed Technology principle. Reed switch relays are sealed from the exterior environment. So, no dust, dirt, and grime mean, it has a long life of wear-free switching. So, these can switch low level signals for numerous operations. On the other hand, electromechanical relays can be susceptible to mechanical failure from impurities from the outside. Therefore, they can switch in the numerous low operations. Most remarkably, no other technology can switch zero current and voltage like these ones. Reed relays are mostly used in electric vehicles, and there has been an increase in the number of electric vehicles on the roads. With the increasing number of electric vehicles, the demand for reed relays will also go up. Going by the numbers, the total demand for these relays will reach USD 1,162 million, by the end of this decade. Read More: https://www.psmarketresearch.com/market-analysis/reed-relay-market
