Introduction to Reed Relays

A Reed Relay, also known as a magnetic reed relay, is a type of electrical switch that uses an electromagnet in order to open or close a circuit. It is a very simple device that relies on the magnetic properties of a ferromagnetic material to perform its switching action.

Reed relays can be used for a variety of applications from switching high power signals to controlling very low power digital signals. They are commonly used in industrial, scientific, and medical applications such as isolation, low-power control, and instrumentation. It is also used in telecommunications for switching small current signals.

DBR72410 Reed Relay

The DBR Series Reed Relay is a dual contact reed relay, designed for low-power applications with both normally-open and normally-closed contacts. The DBR72410 is rated for 25V, 25mA, and 1W. It has a maximum switching current of 25mA and a maximum contact resistance of 10 mΩ.

DBR72410 Reed Relay features a compact DIP-6 package and a low-profile housing, making it ideal for applications where space is at a premium. The dual contact construction provides redundancy while the high reliability of the reed contacts ensures long life in a variety of conditions.

Application Field and Working Principle of DBR72410 Reed Relay

The DBR72410 is suitable for a wide variety of applications. It is commonly used in power circuits, instrumentation, and control systems requiring low-power switches. It can be used as a single-pole, double-throw switch, for controlling power to two loads in alternating sequence. It can also be used for switching small signals in telecom and signaling applications.

The DBR72410 operates on the magnetic reed switch principle. A ferromagnetic core is moved by an electromagnet inside the relay\'s housing. When the coil is energized, the magnet attracts the ferromagnetic core, and closes the two contacts inside the relay. When the coil is deenergized, the magnet releases the core, and the contacts open. The contacts may be operated as either normally-open or normally-closed depending on the coil voltage polarity.

Conclusion

The DBR72410 Reed relay is a versatile, low power, dual contact switch suitable for a variety of applications. It offers reliable switching with a low contact resistance. It has an integrated DIP-6 package with a low-profile design for space-constrained applications. The reed switch design ensures reliable switching in a range of conditions, making it a great choice for control and instrumentation applications.
