Reed relays are widely used in a variety of applications due to their mechanical form factor, low power requirements, and immunity to electrical noise. The DBT71210F-HR is an example of a reed relay that has been specifically designed for applications in which high current switching is involved. The article will discuss the application field and working principle of the DBT71210F-HR reed relay.

The DBT71210F-HR is a high-current, hermetic-sealed reed relay, which is ideal for many applications. It is capable of switching up to 16A and is capable of operating up to 1,500VAC and 5,000VDC. It also features a standard operating temperature range of -55°C to +125°C, and it meets high voltage isolation test requirements (EN6100-4).

One of the primary applications for the DBT71210F-HR is in AC and DC power distribution. These types of systems are often used to distribute power to multiple outlets in a home or commercial building. The DBT71210F-HR is suitable for these applications due to its hermetic-sealed case, which is designed to protect it from dust and voltage spikes. It is also resistant to changes in temperature and is designed to ensure reliable performance under high current conditions.

The DBT71210F-HR is also widely used in industrial automation systems. These systems are often used to control motors, pumps, valves, and other moving entities. The hermetically sealed case of the DBT71210F-HR makes it well suited for these types of applications, as it ensures reliable switching under often harsh operating conditions. The high current capability of the relay also makes it suitable for applications where large loads need to be switched on and off.

The DBT71210F-HR is also used in medical applications, where highly sensitive equipment needs to be switched on and off quickly and reliably. The hermetic-sealed case of the DBT71210F-HR ensures that the relay can operate safely in a variety of conditions, while also providing the reliability needed for these critical applications.

The working principle of reed relays like the DBT71210F-HR is based on the operation of a ferromagnetic core. The core is made up of a coil, which is controlled by a permanent magnet. When a control current is applied to the coil, it induces a magnetic field that interacts with the static field created by the permanent magnet. This interaction causes the core to move, which in turn causes the contacts of the relay to close or open, thus completing or breaking the circuit.

The DBT71210F-HR is a high-performance reed relay that is ideal for many applications. Its hermetic-sealed case ensures reliable operation under severe environmental conditions, while its high current switching capability ensures that it can handle even large load switching demands. Its working principle of utilizing a ferromagnetic core to create a static magnetic field, which is then interacted with the coil, is the basis for its reliable switching.
