Automotive relays are electronic devices utilized in cars, often known as car relays, that are utilized to control various car systems and components either through a switch or electrical signal. Relays enable a low-power electrical circuit to manage flow of a higher electric current and the 9-1393303-7 is one type of these automotive relays.

The 9-1393303-7 is a four-terminal, single throw double pole relay that is utilized in multiple automotive applications. This type of relay is often used as a starter solenoid, and is sometimes utilized in place of contactors for electric engines as well. Other applications of the 9-1393303-7 include fuel pump control, power window control, headlight control, horn control, and power door lock control.

The 9-1393303-7 has a coil voltage of 12V DC, a coil current of 0.3A, a contact rating of 24V DC at 20A, a switching power of 480W, a dielectric strength of 500V, an insulation resistance of 500MΩ, an operation temperature range of -40°C to +125°C, and a contact bounce time of less than 1ms.

The 9-1393303-7 works on the principal of electromagnetic induction. The electromagnetic force in the coil conditionally attracts the surrounding metal contact, causing the relay to operate. When a voltage is applied to the coil, the relay is in a state of rest. When the voltage in the coil is reduced, the armature retraces back to its original state until power is restored to the coil.

The switching action of the 9-1393303-7 usually occurs within milliseconds, depending on load characteristics, and offers lower electromagnetic home during operation. The design of the 9-1393303-7 allows for a simple switch between several functions, and this is why it is commonly utilized in a variety of automotive applications.

The major advantages of the 9-1393303-7 include superior contact performance, low power consumption, a wide range of load currents, and absolute dependability. The long life of the 9-1393303-7 is attributed to its contact design. The contacts are silver plated for increased life and to prevent abrasion and oxidation. In addition, the 9-1393303-7 is also vibration resistant due to its sandwich construction.

Due to its quick actuation and multiple application fields, the 9-1393303-7 is a popular automotive relay to be used in a variety of automotive vehicles. Common vehicle applications of this relay include starter solenoids, power door locks, and window controls. The 9-1393303-7’s abilities to switch between multiple functions makes it an ideal choice for a wide variety of automotive applications.
