Reed relays are contactless electric switches. They usually have two parts: a reed switch, which is made up of two thin metal plates; and an electromagnet. The reed switch has a pair of ferromagnetic contact blades that are attracted and closed when the electromagnet is energized. When the current to the electromagnet is cut off, the blades open. There are various kinds of reed relays, including 7202-05-1101. This type of reed relay is a hermetically sealed one, with proven reliability and performance.

7202-05-1101 reed relay has wide applications in variety of fields. It is often employed in analog circuits or electronic instrumentation in order to provide isolation between circuits and components. It is also used for providing radio-frequency (RF) isolation and in protective switching relays. Another key application of this type of reed relay is its use in security systems, such as motion-sensing alarms, door-open detectors and anti-theft systems.

The working principle of 7202-05-1101 reed relay is usually determined by the design and manufacture process of the Reed switch. When the electromagnet is energized, the two ferromagnetic blades inside the reed switch are attracted and closed, which results in a closed circuit. When the current to the electromagnet is cut off, the attraction between the magnetic blades is released, and the circuit is opened. The opening and closing of the blades are triggered and regulated by the electromagnet.

The performance of 7202-05-1101 reed relay is usually high, because of the hermetic sealing process. This process allows the relay to be resistant to dust, dirt, and moisture. Thus, these relays can perform stably and reliably for a long period of time. The contact resistance is also usually small, which makes the switching action fast and smooth.

In summary, 7202-05-1101 reed relay is a type of contactless electric switch. Its wide applications include analog circuits, digital electronic instrumentation, security systems, etc. Its working principle is that when the electromagnet is energized, the two ferromagnetic blades inside the reed switch are attracted and closed, which results in a closed circuit. When the current is cut off, the blades are opened again. Overall, this type of reed relay has proven high reliability and excellent performance due to its hermetic sealing process.
