Reed relays are electronic switches based on a magnetic field. They consist of at least two, and sometimes three or four, ferromagnetic reeds hermetically sealed in a glass vacuum tube or porcelain envelope. Depending on the nature of the contacts, they may be used to connect a normally open (NO) circuit, normally closed (NC) circuit, or a single or dual-pole circuit. They possess several features which make them attractive for many applications including low power consumption, long lifetime, and low parts counts.One popular example of a reed relay is the 7103-05-1011. This relay is designed for applications where a high level of reliability, high temperature operation, and a low contact resistance is required. It has an operating current of up to 5A and an operating voltage of up to 10kV, making it suitable for a wide range of applications. The 7103-05-1011 utilizes a hermetically sealed housing with a secure, snap fit lid for added protection. This ensures that the contacts remain securely in place even in environments where the unit is exposed to high levels of vibration.In order to understand how a reed relay works, it is important to understand the workings of its component parts. The relay has two primary components: the reeds and the coil. The reeds consist of a pair of thin ferromagnetic sheets held in close proximity within the relay. When an external magnetic field is applied, the reeds become magnetized. This magnetic field induces eddy currents in the coil, causing it to generate a magnetic field of its own. This generated field interacts with the reeds, causing them to move apart. In turn, this causes the contacts in the relay to switch states, either connecting or disconnecting the circuit.The 7103-05-1011 relay is suitable for a wide range of applications, including control and automation systems, motor drives, pumps, HVAC systems, electronic appliances, and heaters. They are often used in automated systems where frequent switching is required. Additionally, their low power consumption and high reliability make them a good choice for applications that require consistent and reliable operation. In summary, the 7103-05-1011 relay is an excellent choice for applications that require a reliable and low-power switching solution. By understanding the working principle of the reeds and coil, it is easy to see why this relay is suitable for so many applications in different industries.
