Upfitter Auxiliary Switches (RPO 9L7)
- Integrated Diode: Each relay includes a built-in diode that suppresses induced voltage during switching, safeguarding your electrical components from potential damage.
- Small size/Low power consumption/High contact voltage/ High sensitivity.
- Contact Material: Ag Alloy / Contact Resistance: ≤ 100MΩ.
- Minimum operating voltage 8V, corresponding minimum operating current is 100mA; Standard operating voltage 12V, corresponding standard operating current is 150mA.
- Life Expectancy Electrical: 100,000 Operation, Life Expectancy Mechanical: 10,000,000 Operation.
- Never go beyond its capabilities. Try to stay 10 to 15% below what the rate is for
- 12-volt 5-prong (SPDT) relay. Excellent water-repellent and dustproof ability, but do not use it in water
- Be careful when inserting the relay into the socket. If you force it, you will bend the female connectors
- Primary leads use 12 a.w.g tinned copper wire. Coil leads use 16 a.w.g
- Nominal Coil Voltage: 12 V DC; Coil Power: 1.8 W; Coil Resistance: 80 Ω; Must Operate Voltage: 6~8 V DC; Must Release Voltage: 0.6~3.6 V DC; Maximum Applied Voltage: 15.6 V DC
- High switching capability: Normally open 40A/14V DC and normally close 30A/14V DC. Suitable for Nilight LED light bar wiring harness kit
- Premium quality: Durable relay and harness socket with 5 wires; Made by high-grade materials to ensure superior quality and long lifespan
- Male-female slot design: Unique male-female slot design, easy to connect the relay with harness socket, clean and neat after installation
- Easy wiring: The relay sockets come with different colors for loads/accessories, simple and convenient wiring
- Package include: 5 x relay and 5 x relay socket with wires.Fit type: Universal fit
- 【12V 40A PEAK CAPACITY】Rated for 12V DC systems with a 40A max peak switching current (1.8W coil power, 80Ω resistance). Always keep your continuous loads 10% to 15% below the rated value to ensure maximum electrical safety and relay longevity
- 【PREMIUM AgSnO2 CONTACTS】This 4-pin SPST automotive relay features premium Silver Tin Oxide (AgSnO2) contacts for maximum resistance to arc erosion and contact welding. Rated for a 27V DC max switching voltage, it guarantees extended operational durability and reliable switching performance under heavy loads
- 【14AWG TINNED COPPER】Unlike inferior aluminum wires, our premium tinned copper design offers superior conductivity and is far more corrosion-resistant than standard bare copper. Specs: 16AWG (85/86) for control, and 14AWG (30/87) for reliable standard power output
- 【WEATHER-RESISTANT】Engineered with a tight housing to protect internal contacts from moisture, dust, and debris. Ideal for under-hood installations and outdoor applications. Please note: This unit is splash-proof only; do not submerge completely in water
- 【PLUG & PLAY VERSATILITY】Designed for a quick, hassle-free setup to reliably wire LED work lights, standard fog lights, auxiliary water pumps, air horns, and DRLs. Please check the relay dimensions (2.44 x 1.77 x 1.38 inches, excluding wires) prior to purchase to ensure proper mounting clearance
- Quality Material: The a/c relay housing is made of PA66 flame-retardant material with pure copper enameled wires to ensure excellent heat dissipation and magnetism, which enhances resistance to high temperatures and arc erosion, providing excellent conductivity and long-term reliability
- Excellent Waterproof Performance: The fuel pump relay base is sealed and waterproof with IP67 protection level, waterproof and dustproof, able to work stably in all kinds of humid environments, ensuring long-term reliability and durability of the relay
- Relay Specifications: Package contains four starter relays, each model number JD1914-12V-40A, five-pin design, size 1.07 x 0.98 inches, coil power 1.8 watts, coil resistance 90Ω
- Easy Installation: The five-pin design of the radiator fan relay makes it easy to replace an existing relay by simply connecting the appropriate wires to the corresponding pins. No additional tools are required, making the installation process easy and quick to accomplish in tight spaces
- Wide Application: The relays are widely used in a variety of electric vehicles such as automobiles, motorboats, etc. The relay box can be a nice replacement for 582195, 582472, 582473, 584416, 586147 and 586224. They can also be used in a variety of application scenarios such as automotive taillights, electric cooling fans, electric water pumps, motor starters and motorcycle conversions
