PCB RelayDownload
A PCB relay is a device used to provide electrical circuits on and off. It consists of a coil of wire that is wrapped around a ferromagnetic core. When a current is applied to the coil, it generates a magnetic field that activates the relay. It is typically used to isolate signal or control circuits from power circuits or to isolate one circuit from another. PCB relays are available in a variety of sizes and configurations and are used in a variety of industries, including automotive, aerospace, and communications.
It is evident that the PCB relay offers a multitude of benefits over other types of relays. Some of the most notable advantages include its compact size, its lightweight, and its ability to operate at high speeds. In addition, PCB relays are less likely to experience radio frequency interference.

What are the different types of PCB Power Relay?
A PCB power relay is an electromechanical device used to control the flow of current in a circuit. There are many different types of PCB power relays, each with unique characteristics and applications. The most common types of PCB power relays are solid state relays, reed relays, and mercury relays.
Solid state relays are the most common type of PCB power relay and are typically used in low power applications. Reed Relays are used in high power applications, typically in automotive and industrial applications. Mercury relays are the most expensive type of PCB power relay, but they provide the highest level of surge protection.
Finding and Sourcing PCB Relays
When purchasing a PCB relay, it is important to consider the specifications and requirements of the application, such as rated voltage and current, contact configuration, switching speed and reliability.
When selecting a supplier, you should also consider factors such as lead times, pricing, and minimum order quantities. It may be helpful to request samples or test the relays in your application before placing a large order to ensure they meet your requirements. Shenle provides you with the supply chain visibility you need to find the relays you need for your high power circuit boards.
PCB Power Relay Features
PCB Power Relays’ compact size and multi-contact configuration make them ideal for many electronic systems and devices.
Some key features of PCB power relays include:
High Current and High Voltage Handling: PCB power relays are designed to handle high currents and high voltages, typically up to several amps and hundreds of volts. This makes them suitable for applications requiring high power levels.
Low Power Consumption: PCB power relays typically consume little power when not in use, making them ideal for battery-operated equipment or other applications where power consumption is a concern.
Compact size: PCB power relays are typically small and lightweight, making them easy to integrate into electronic circuits and systems. This makes them a popular choice for space-constrained applications.
Long Life: PCB Power Relays are durable and reliable and will last for many years. They are designed to withstand repeated use and are often designed to withstand harsh environmental conditions.
Low Coil Power Consumption: PCB power relays typically require low coil power consumption to activate the relay, resulting in low power consumption and high energy efficiency.
High Contact Reliability: PCB power relays feature high contact reliability, low contact resistance and low contact bounce, which prolongs the life of the relay.
Multiple Contact Configurations: PCB power relays are available in a variety of contact configurations including Single Pole Single Throw (SPST), Single Pole Double Throw (SPDT), Double Pole Double Throw (DPDT), and more. This makes them suitable for a wide range of applications.
PCB Power Relay Application Examples
PCB power relays are versatile devices that can be used in many different applications requiring high current and voltage handling capabilities.
Some examples of PCB power relay application areas include:
Power Supply
PCB power relays are commonly used in power supply circuits to switch high currents and voltages. They can be used to control AC or DC power inputs, switch between different voltage levels, or protect circuits from overload or short circuits.
Motor Control
PCB power relays are also used in motor control circuits to switch the current to the motor. They can be used to start and stop a motor, change its direction of rotation, or control its speed.
Automotive Applications
PCB power relays are used in many automotive applications such as headlights, windshield wipers, and cooling fans. They can also be used to control power flow in battery charging systems, switch between charging modes, or protect batteries from overcharging or discharging.
Industrial Control Systems
PCB power relays are used in various industrial control systems such as conveyor belts, pumps, and lighting systems. They can be used to switch the flow of power to different parts of the system, control the timing of operations, or protect the system from overloads or short circuits.
Home appliances
PCB power relays are used in many home appliances such as refrigerators, air conditioners, and washing machines. They can be used to control power flow to different parts of equipment, switch between different modes of operation, or protect equipment from overload or short circuits.
