Introduction to DBT72410TU Reed Relay

DBT72410TU is a special kind of reed relay that is designed especially for dry contact relay applications ranging from low voltage to high voltage requirements. It is known for its high power contact rating and unique combination of low contact resistance and high insulation resistance. This relay is considered to be a semi-sensitive type which measures the position of the actuating magnet by detecting a strong magnetic field.

Application Fields of DBT72410TU Reed Relay

DBT72410TU Reed Relay is applicable for use in dry contact applications such as power contactors, contactors for switching high power and various other applications such as pulse generators, switching power supplies, AC/DC motor controls, and telecommunications. It can also be used in industrial products, and consumer devices, such as capacitors, resistors, surge protectors, alarms and control systems.

Working Principle of DBT72410TU Reed Relay

The working principle of DBT72410TU reed relay is based on a principle called the Ampere Force Law. This law states that an electric current in a coil, that has a magnetic field around it, will act on an adjacent magnet and will create a force. When the force created by the current is greater than the forces of the field produced by the magnet, the reed switch will be activated and the contacts will open or close. Therefore, when an actuating magnet is placed close to the reed relay, the contact closing force of the relay will be greater and the contacts will be closed. When the magnet is removed, the contacts will open.The source of power for the reed can either be direct current (DC) or alternating current (AC). The current required to actuate and de-actuate a particular relay will depend on its voltage rating. DC voltage can usually be as low as 2.5 volts, while AC can be anywhere from 1 to 10 volts.

Conclusion

DBT72410TU Reed Relay is designed for various types of dry contact relay applications from low voltage to high voltage requirements. It is characterized by low contact resistance and high insulation resistance with high power contact rating. Its working principle is based on the Ampere Force Law, whereby the electric current in a coil creates a force exceeding the forces of an actuating magnet’s field, closing and opening the contacts as required. This versatile relay can be used in many applications, including power contactors, pulse generators, switching power supplies, AC/DC motor controls, telecommunications and various consumer devices.
