23 lut 2017 · Reed relays contain a reed switch, a coil for creating a magnetic field, an optional diode for handling back EMF from the coil, a package and a method of connecting the reed switch and the coil to the outside of the package.
A reed relay uses an electromagnet for controlling one or more reed switches. An electromechanical relay works by using a magnetic field generated by an electromagnetic coil once a control signal is applied to it.
This tutorial serves as a quick primer on reed switches and demonstrates how to hook them up and use them. Beyond the switch itself, the following materials are recommended: Magnet -- You'll need something to actuate the reed switch, and this small magnet should fit the bill.
This paper will explore reed relays, how they are manufactured, and explain how to utilize them to maximize the reliability of your designs.
Long reed relay life and dynamic contact resistance \⠀ 䐀䌀刀尩 go ‘hand in hand’. Understanding dynamic contact resistance is an \൩mportant step to better selection of the right reed relay for the right application.
26 paź 2023 · The magnetic field, necessary for the operation of a reed relay, is generated by the coil. When electricity passes through this coil, it induces a magnetic field, attracting the metal reeds towards each other, resulting in the closing of the circuit.
21 gru 2021 · Reed relays have a relatively simple way of working. When voltage is applied, the reed relay electromagnetic coil produces a current. Secondly, the current produced by the electromagnetic coil will release a magnetic field, which closes the reed relay’s switch contacts.
