Reed relays are well-known for being a reliable electrical switch that employs an electromagnet as its actuating mechanism. A reed relay typically consists of a reed switch enclosed in an airtight case, with movable reeds and contacts, and a laminated anisotropic material filling the core of the magnet. The movement of the reed switch is caused by the interaction between the magnetic field and the electrical current passing through the contacts of the switch. Specifically, when an electric current is applied to the reed switch, the magnetic field provided by the switched current interacts with the magnetic field of the anisotropic material, causing the reeds to move back and forth rapidly. This alternating movement of the reeds causes the reed switch to open or close its contacts, thus controlling the current through the relay.

DAT200-05 is a high-performance and compact reed relay, developed by the Taiwanese telecommunications manufacturer, AT&T. It is designed to be used in a wide range of applications including communication systems and general-purpose computer systems. The DAT200-05 is able to switch at frequencies up to 200kHz and has a nominal operating temperature range of 0 °C to +125°C. It features an advanced reverse blocking chip which makes it possible to use the same relay to select from two different voltage sources. The DAT200-05 reed relay is a cost-effective and high reliability solution for applications requiring reliable switching.

The working principle of the DAT200-05 relay is based on an electromagnetic effect. When the current passes through the metal reed of the relay, it creates an electromagnetic field that interacts with the metal core inside the relay. The interaction between the magnetic field and the core causes the reed to flex and move back and forth rapidly, closing and opening the contacts of the reed switch. The rate at which the contacts switch is determined by the frequency of the current passing through the reed switch. The alternating motion of the reed switch produces a pulsating effect that can be used to control current in any selected combination of settings, such as on/off, full on/half on, or full off/half off.

The primary application field of the DAT200-05 reed relay is in the telecommunications industry where it is used for switching signals between different components and systems. For example, they are used in telephone switching systems to route calls, in telecom equipment to select from multiple current sources, and in control panels for managing voice and data transmissions. The DAT200-05 is also used in computer and data transfer systems to provide reliable switching. In addition, the DAT200-05 can be used to isolate signals in audio, video, and instrumentation applications.

The DAT200-05 reed relay is a reliable, high-performance, and compact switch, designed to meet the needs of a variety of applications. With a low on-state resistance of less than 2Ω, high-frequency switching capability, and reverse blocking chip, the DAT200-05 offers a reliable and cost-effective alternative to traditional mechanical switches. It is highly suitable for use in a wide range of communication and computer systems, as well as for isolating signals in audio, video, and instrumentation applications.
