Reed relays are electrical switches that are activated by the control signal supplied by an external magnetic field. They are effective in providing high isolation between two circuits and they consume minimal energy. The HE3621A6012 is an example of a reed relay that operates with a 12V DC supply voltage. This particular relay is available in a standard package and is designed for general purpose switching applications such as in remote control circuits, home appliances, and computer systems.

The HE3621A6012 is an open-contact type switch that features a built-in sensor coil. The sensor coil is composed of a flat copper winding that runs through the center of the relay. This winding is energized when an external magnetic field is applied, and responds by opening or closing the switch contacts. The switch contact opening and closing is essentially an electrical switch, with the switch contacts being kept mechanical stable, opened or closed depending on the strength of the external magnetic force. This type of reed relay offers an extremely high isolation between the two circuits, allowing signals to pass from one to the other without any contamination from the other circuit.

The operating principle of the HE3621A6012 is fairly simple. When a 12V DC voltage is applied to the coil, the sensor is energized and a magnetic field is created. When the external magnetic field is applied to the coil, the contacts within the relay open or close depending on the strength of the magnetic field. The contact position is maintained until the magnetic field is removed or weakened to the point where the contact position is no longer sustained.

The main applications of the HE3621A6012 include its use in low voltage and low current remote control circuits, home appliance control, and computer system applications. It is also suitable for signal control in industrial machines, audio systems, or automobile controllers. The small size and low power consumption of the HE3621A6012 makes it ideal for use in applications where space is limited and energy consumption is desired. The HE3621A6012 also offers noise protection in circuits operating in electrically noisy environments, or when precise timing is needed.

The HE3621A6012 is an example of a reliable reed relay technology and it provides an effective solution for various general purpose switching applications. Its small size and low power consumption make it an ideal choice when design considerations are paramount. Furthermore, its exceptionally high insulation strength provides superior signal isolation between circuits, allowing signals to pass through with minimal interference from other circuits.
