PCB electromagnetic relays are an essential component in modern electronics, offering a practical solution for controlling high-power devices with a low-power signal. These relays are commonly found in various industries, including automotive, telecommunications, and consumer electronics. This article will explore the functionality, applications, and benefits of PCB electromagnetic relays, shedding light on their role in circuit design.
What is a PCB Electromagnetic Relay?
A PCB electromagnetic relay is a type of electromagnetic switch designed to be mounted directly onto a printed circuit board (PCB). It operates by using an electromagnet to physically move an armature, which in turn opens or closes electrical contacts. The coil inside the relay is energized by a low voltage, creating a magnetic field that causes the armature to either connect or disconnect the relay contacts. This enables the relay to control high-power or high-voltage circuits, even if the control circuit uses a much lower voltage.
