Reed Relays

Reed relays are an electronic switch which use an electromagnet to control a mechanical arm. The arm is usually in the shape of a dome or paddle, and is held in place by a thin strip of metal known as the reed. When the electromagnet is energized, the magnetic field attracts the arm and causes it to open, closing an electrical circuit.

DBT71210F Application Field and Working Principle

The DBT71210F reed relay is a versatile and powerful tool for applications requiring both high-speed switching and low-power consumption. The relay is designed to replace bulky and noisy conventional relays while providing superior performance. It can be used for switching AC and DC circuits, controlling audio and video signals, controlling security systems, and more. The relay is robust against environmental conditions such as temperature, humidity, UV light, and general contamination.

The DBT71210F relay uses two reeds to control the switching of the electrical circuit. The first reed is mounted in the pole area and controls the movement of the armature. The second reed is suspended in the air gap and creates an inductive field in the gap. The pole and armature move together and create a closed circuit when energized by the current passing through the gap.

The DBT71210F reed relay is designed to offer high performance in all kinds of applications. The switching time is optimized to reduce the power consumption, and the internal circuit is protected against accidental short circuit or over-current. The contact material is corrosion resistant to ensure long life and reliable operation. Additionally, the relay features low voltage drop and high operating temperature range. The contact resistance is also low, making it ideal for switching low-impedance loads.

Overall, the DBT71210F reed relay is a reliable and versatile solution for switching AC/DC circuits. It can be used in a variety of applications, offers superior performance and low power consumption, and is robust against environmental conditions.
