12V DC Waterproof Relay Kit

【SUPERIOR SEALED PROTECTION】 Designed with a rugged, waterproof housing, this relay offers excellent resistance against water splashes, dust, and corrosion. Important Note: While highly water-repellent and ideal for harsh environments (under-hood, marine, off-road), please ensure it is not submerged directly in water to maintain optimal performance and longevity.

【HEAVY-DUTY WIRING & SPECS】Engineered for high-load applications in large-displacement vehicles. The primary switching leads utilize 14 AWG tinned copper wire for superior current carrying capacity and corrosion resistance, while the coil leads use 18 AWG. Rated for 40/30 Amps at 12V DC, this relay is specifically optimized to deliver stable voltage to electronic rearview mirrors on vehicles with engines larger than 3.6 liters, effectively supporting the power demands of integrated cameras, displays, and heating elements while preventing voltage drops in complex electrical systems.

【PRECISE SOCKET FITMENT】 We use high-quality copper terminals for a secure connection. Pro Tip: When inserting the relay into the socket, please align the pins carefully and insert gently. Avoid using excessive force to prevent bending the internal female connectors, ensuring a long-lasting, tight fit without looseness.

【STABLE ELECTRICAL PERFORMANCE】rigorously tested for stability. Features a nominal coil voltage of 12V DC (1.8W power, 80Ω resistance). It guarantees a "Must Operate" voltage of 6~8V DC and releases safely at 0.6~3.6V DC. This precise engineering prevents misfiring and ensures your automotive accessories activate exactly when you need them.
