Reed relays are electromechanical switches that use an electromagnetic core, or reed, to open or close the electrical circuit. They are commonly used for electrical isolation and signal routing, such as in instruments, computers, and other control systems. The BFH-3A-12 is one such reed relay.

The BFH-3A-12 is a subminiature reed relay with a high contact rating. It is powered by a 2 A DC current, has a 16 VAC/DC coil rating, and is equipped with dual normally open contacts. The contacts are rated up to 30VDC/250VAC, 5A, and they are sealed for protection against dust and moisture. The relay is designed with a high insulation resistance of more than 100Mohm at 500Vdc, and it has a low coil power of just 40 mW. It is suitable for a variety of applications, such as in computers, instrumentation, industrial process control, and other control systems.

The BFH-3A-12 reed relay works by using a magnetic field to switch contact states. When an electrical current is applied to the coil, the core, or reed, is pulled into a closed position, and the contacts are closed. When the current is switched off, the reed is released and the contacts open. This simple operation means that the relay can be switched at very high speeds, with switching times as low as 10 milliseconds.

In addition to its performance benefits, the relay also offers advantages in terms of its physical design. It is a small device, measuring just 25.4 mm x 15 mm x 15 mm, and has a weight of only 6 grams. This makes it an ideal choice for use in applications where space is limited, such as for medical devices, test equipment, and signal routing systems. It also has excellent insulation properties, providing protection against electrical shock, as well as protection from electrical interference.

The BFH-3A-12 reed relay is an ideal choice for a wide variety of applications, such as in computers, instrumentation, industrial process control, and other control systems. It has excellent electrical protection properties, and a contact rating of up to 30VDC/250VAC, 5A. The relay is small and lightweight, making it suitable for applications where space is limited. It also has a very fast switching time, allowing for high speed operation.
