Reed relays are used in a variety of applications, from industrial and automotive to medical and consumer electronics. The 7003-5118 reed relay is used in low voltage and current applications, such as microcontrollers, where a switch is needed but space is limited. In the specific case of the 7003-5118, it is a reed relay with a sealed enclosure. It is composed of a glass tube containing two ferromagnetic reeds, meaning the cylinders are made of a material that can be magnetized or demagnetized. A coil, also known as an armature, is wrapped around the glass tube and, when an electrical current is applied to the coil, it creates a magnetic field. This magnetic field causes the reeds to move and come into physical contact, allowing the current to flow.

The 7003-5118 reed relay is used when there is a need for low voltage and current applications. It can be used to control motors, power devices, or detect other current levels, making it ideal for applications such as microcontrollers. The reed relays are also useful for providing isolation of a circuit, as well as protecting certain components from unexpected voltage spikes. Additionally, the switch created by the 7003-5118 has a very fast response time, which in certain applications and situations can be beneficial.

When an electric current is passed through the magnetized reeds, it causes them to be attracted to one another. This brings the two contacts, known as the armature, together, allowing the current to flow through the device. When the current is removed, the reeds lose their magnetism and return to their original position, thus breaking the circuit. Through this mechanism, the 7003-5118 reed relay can be used to control electrical devices by switching them on and off.

The 7003-5118 reed relay also offers a number of advantages. It is extremely reliable, as the reeds do not wear out with repeated use, so the contacts remain as consistent as the day they were first manufactured. Additionally, the contact resistance remains low over time, making it the ideal solution for low voltage and current switching applications. Moreover, due to its small size and low power consumption, the 7003-5118 reed relay is a great choice for applications in which space is at a premium.

The 7003-5118 reed relay is an excellent choice for low voltage and current applications, offering reliability, low contact resistance, and a small form factor. Its application field will continue to expand, making it an increasingly popular choice in a variety of industries. It is an important component in a variety of industrial applications and can provide crucial protection and isolation in situations where it is needed the most.
