Reed Relays are electromechanical relays which use a magnetically activated reed switch typically enclosed in a hermetically sealed glass envelope, although a variety of non-magnetic materials are now also used. The popular DBT72410F is an example of such a reed relay, with a variety of applications and a straightforward operating principle.

Designed for broadcast equipment applications, the DBT72410F features a 10A contact rating and is suitable for DC and AC use. Its basic operation depends on two opposing reed switches that are housed separately from the contact. It operates on a coil voltage, and is actuated using a control circuit which energizes the coil, thus creating a magnetic flux which closes the reed switches, thus closing the circuit.

The major features of the DBT72410F relay include a high switching capability, a low operating current, a fast response time and a low leakage current. Additionally, its compact design makes it suitable for a variety of broadcast equipment applications. Its insulation resistance of >1000MΩ and contact resistance of ≤30mΩ make it ideal for sensible electrical connections. The fast response time eliminates contact bounce and the low power consumption allows the relay to operate reliably over a wide temperature range.

The simplicity of the DBT72410F’s design means that it can be used in a wide variety of applications. It is ideal for use in the telecommunications and electrical engineering industries, where it can be relied upon for switching moderate currents in low-voltage circuits. It is also suitable for the testing and robotics industries, where its quick and reliable switching capabilities make it particularly useful. Finally, it is ideal for use in customer entertainment systems, where its low power consumption and long-lasting durability are particularly attractive.

The operation of the DBT72410F reed relay is straight-forward. To energize the contact, an external control circuit supplies an alternating current (AC) or direct current (DC) to the magnetised coil, thus producing a magnetic flux which closes the contact’s reed switches. The relay can then be energised with up to 10 amps of current, allowing the contacts to close. When the external control circuit ceases to supply the current, the magnetisation of the coil is far less, causing the contact’s reed switches to open, and thus opening the contact.

In summary, the DBT72410F reed relay is a versatile and reliable device that is suitable for a variety of applications. Its insulated design and efficient energy consumption make it ideal for electrical engineering and the broadcasting industry. Its simple operating principle makes it easy to use, and its fast response time ensures reliable and safe operation in demanding applications.
