Reed Relays

BF-1C-12 Application Field and Working Principle

Reed relays are electromagnetic switches that are used in many different fields. They are particularly useful in many electronic applications, such as control circuits, protective circuits, switching power supplies, and other applications requiring high-speed switching. The BF-1C-12 is a reed relay, manufactured by Fujitsu, and is designed for use in electronic circuits.The BF-1C-12 is a single-pole, double-throw reed relay with a single-coil latching mechanism. It is a miniature device with a contact spacing of 20 µm, and has a contact resistance of 0.1 milliohor, with a life of 100 million operations. It is an SPDT (single-pole double-throw) type, meaning it has two stable positions, on and off. The on position allows current to flow through the coil, while the off position does not. The maximum switching voltage is 250VAC, and the maximum coil voltage is 10VDC.At the core of the relay is the reed, which is a tiny strip of metal that can move when a magnetic field is applied to it. The reed is connected to a contact arm, which moves the contacts of the relay to either the open or closed position. The coil of the relay produces a magnetic field when energized, which causes the reed to move and close the contacts. When the coil is de-energized, the reed returns to its original position, opening the contacts.The BF-1C-12 can be used in various applications, such as motors, actuators, electrical and electronic equipment, and other devices. It is well suited for applications requiring high-speed switching and long life. It can be used as a protective or control device, as well as a switch for power supplies.Using the BF-1C-12 is relatively straightforward. The connections for the coil and contacts are clearly marked, and only two wires are required for the coil. The direction of current flow must be observed when connecting the coil, as reverse polarity can damage the device. An LED may also be used for indication.In summary, the BF-1C-12 is a small-size reed relay manufactured by Fujitsu. It is a single-pole, double-throw relay with a single-coil latching mechanism. It can be used for a variety of applications, including protective and control devices, and can switch up to 250VAC. It has a contact resistance of 0.1 milliohms, a life of 100 million operations, and a coil voltage of up to 10VDC. Using the BF-1C-12 is relatively straightforward, and it is an excellent choice for many electronic applications.
