Automotive relays are a type of electro-mechanical device used to allow a relatively low current control signal to control the flow of a large current. They are used in a wide range of vehicles, including automobiles, motorcycles, snowmobiles, and other recreational vehicles. The most common use of a relay is to start the engine of a vehicle when the ignition switch is activated.

2-1393302-3 automotive relays are high-performance types with a wide range of applications. They are designed to operate in continuous-duty, electromagnetic-interference (EMI)-free environments and are available in several air gap options. In addition, they feature a unique dual-coil design that allows them to operate in both single and dual-coil mode, thus providing greater versatility.

The most important application of the 2-1393302-3 automotive relay is for engine starting. It is designed to allow a small current control signal to be used to start a larger current for the engine. The typical design consists of two coils and a molded plastic outer shell. The inner coil is energized when the starter switch is activated, which causes a magnetic field to be created. This magnetic field then attracts a moveable armature which closes a set of contacts. These contacts allow the current from the starter switch to be transferred to the starting motor of the vehicle.

The primary advantage of the dual-coil design of the 2-1393302-3 automotive relay is its ability to reduce electrical noise. In a single-coil configuration, excess noise generated by the coil can cause the relay to cycle too quickly. This can lead to premature failure of the relay or malfunctioning of the circuit being controlled. By using two coils, the amount of noise generated is greatly reduced, thus improving the reliability of the system.

The 2-1393302-3 also has a unique type of protection built into it. This is known as “seizure” protection. When the initial current output is turned off, the relay will continue to draw a small amount of current until the magnetic field dissipates. This prevents the relay from sticking open and preventing the starter from functioning.

The 2-1393302-3 automotive relay is used in a variety of applications, including engine starting, auxiliary lighting, trailer brakes, and various electronic applications. It is designed to provide reliable, interference-free operation in all environments. It is highly reliable and cost-effective, making it an ideal choice for automotive applications.
