The PCB (Printed Circuit Board) electromagnetic relay is a crucial component used in electronic systems to control high-power circuits with low-power signals. It is designed to be mounted directly on the PCB, allowing it to be easily integrated into a wide variety of electronic applications. The electromagnetic relay operates on the principle of electromagnetism to switch electrical circuits, making it indispensable in industries such as telecommunications, automotive, industrial automation, and consumer electronics.
Working Principle of PCB Electromagnetic Relay At its core, the PCB electromagnetic relay consists of a coil of wire, an armature, and one or more contacts. When an electric current passes through the coil, it generates a magnetic field that attracts the armature. The movement of the armature causes the contacts to either open or close, depending on the relay’s configuration. This action effectively controls the flow of electricity through the circuit, turning devices on or off without requiring a direct electrical connection to the high-power components.
