Advantage of Plug in Relay

Physical parameters such as pinout and casing are standardized. As long as electrical parameters like current and voltage meet usage requirements, replacement installation is feasible.

We offer plug-in automotive relays certified by UL, CE, and other standards, manufactured to ISO 280 relay specifications under the IATF 16949 quality system.

We offer hundreds of auto relay models for you to choose from, designed to fit the installation space and meet the operational requirements of various vehicles.

Foocles has consistently adhered to the use of pure copper coils, ensuring stable and reliable automotive plug in relay engagement.
Premium Relay Materials Deliver Lasting Magnetic Adhesion
Since Foocles founding, our company has used pure copper coils wound with red copper wire as the core component of every automotive plug in relay. This ensures the auto relay coil can reliably and rapidly control contact operation. Simultaneously, the high conductivity, arc resistance, and oxidation resistance of our silver alloy contacts enable our plug in relays to achieve a lifespan exceeding 80,000 operations.

If you need a automotive relay supplier with ultra-fast lead times, Foocles is your best choice. We maintain extensive warehouses to manage inventory of standard relay models, while our eight automated production lines enable rapid production adjustments, achieving a daily output capacity exceeding 100,000 units.
For non-standard custom relays, our experienced staff can swiftly assemble, test, and complete packaging. When you partner with Foocles, we always operate at full capacity to ensure delivery in the shortest possible time.
New Directions for Plug-in Relays
As automotive functional requirements continue to evolve, vehicle modification has become a viable option. Foocles plug in relays can be installed within control box modules to provide control for your added electrical components.
Whether it’s controlling spotlight modes or lift pedals, Foocles offers the right relays for the job. We also provide custom relay solutions for new application scenarios.

Dynamic Plug-in Relay Manufacturer in China
We firmly believe that for a company to thrive, it must seize opportunities and embrace innovation. By gathering market intelligence and analyzing customer feedback, we have developed the following new products featuring relay technology.

We assembled the plug in relays and fuses into a convenient electrical control box using modules and wiring harnesses.

The control panel and chip have been added to the Relay box, providing more intuitive control methods and wireless control.

Mount the high-current car relay securely on the panel to provide forward and reverse control capability through the relay’s changeover contacts.

We have integrated multiple plug in relays within the product to prevent the two batteries from charging or discharging each other.
