Reed relays are one of the most significant components of electrical and electronic devices. They are used to isolate circuits and switch signals, and are a vital part of many common devices such as calculators and computers. The JWD-172-7 is one of the most popular reed relays on the market today. It is a double-pole double-throw (DPDT) reed relay that has two normally open (NO) switches and two normally closed (NC) switches. Its performance is particularly outstanding when compared to other reed relays.

The JWD-172-7 is designed to operate at a voltage between 5 and 24 volts and a current up to 1.25 Amps with a maximum contact resistance of 10 milli-ohms. It has an activation time of 1 millisecond and a deactivation time of 0.2 milliseconds. It also has an average life cycle of 10,000,000 operations. The casing of the JWD-172-7 is designed to provide maximum protection for the delicate components inside.

The main application field of the JWD-172-7 reed relay is in circuit isolation and switching. It can be used in electromechanical switches, motors, and alarm systems to control the flow of electricity. It is also effective for connecting and disconnecting circuits in many electronic devices such as computers and calculators. In addition, the JWD-172-7 is ideally suited for use in applications requiring low voltage and current. As such, it is often used for signal control in radio devices, navigation devices, and other electronic systems requiring low current.

In order to understand how the JWD-172-7 reed relay operates, one must first understand the construction of a basic reed relay. Reed relays consist of a hermetically sealed, glass tube containing two or more pieces of ferromagnetic material (often referred to as reeds). When a voltage is applied, the ferromagnetic material becomes magnetized and pulls the switch contacts together, connecting them and allowing current to flow. When the voltage is removed, the contacts separate and the current flow stops.

The JWD-172-7 reed relay is specifically designed for low-current and low-voltage applications. It contains two sets of contacts, one normally open and one normally closed. When the voltage is applied, the contacts on the normally open side are closed and the contacts on the normally closed side are opened. This allows current to flow from the normally closed side to the normally open side. When the voltage is removed, the contacts on the normally open side are opened and the contacts on the normally closed side are closed, thus allowing the current to stop flowing. This makes the JWD-172-7 an ideal device for switching applications, since it ensures that current is only flowing when it is supposed to.

In conclusion, the JWD-172-7 reed relay is an excellent component for circuit isolation and switching applications. Its design allows for low-current and low-voltage operations. Its double-pole double-throw structure allows for the control of current flow in both directions. In addition, the JWD-172-7 has a long life cycle and offers excellent protection against the elements. All of these features make it one of the most popular reed relays on the market today.
