Reed relay is an electromagnetic device that uses an enclosed reed switch as a switching component. It consists of an open type reed switch enclosed in a hollow sealed tube and an electromagnet coil with an iron core. The iron core is surrounded by a thin, rigid insulating material. When a certain level of current is passed through the electromagnet coil, the magnetic field created by the coil attracts the reed switch to close the contact. The contact closes and opens in response to the current passing through the coil, thus controlling the flow of electricity.

The 7122-12-1000 is a specialized type of reed relay. It is designed to switch very low voltages, such as those used in logic circuits. The 7122-12-1000 is a single-pole, single-throw (SPST) switch, which means it has a single contact that opens and closes with a single electrical pulse. The 7122-12-1000 is designed to work with a minimum of 12 volts and a maximum of 24 volts DC.

The working principle of the 7122-12-1000 is fairly simple. When voltage is applied to the contacts, the electromagnet creates a magnetic field that pulls the reed switch closed. Once the contact is closed, current is allowed to pass through the contacts and a circuit is completed. To open the switch, the electromagnet must be de-energized. This reduces the magnetic field to zero and releases the reed switch, allowing it to open the contact. This effectively interrupts the current flow through the contacts, effectively breaking the circuit.

The 7122-12-1000 is a useful device for controlling low-voltage circuits. They are commonly used in computers where they are used to control logic circuits, as well as in telecommunications, medical and automotive applications. The 7122-12-1000 also finds use in burglar alarm systems, as the reed switch can be used to detect movement or vibration. Due to their low cost and reliability, the 7122-12-1000 is a popular choice for low-voltage control applications.
