4-1393306-6 Relays

Automotive relays are used in many automotive applications, from engine control to lighting. The 4-1393306-6 automotive relay is a 5-pin SPST (single-pole-single-throw) relay used primarily in engine control and powertrain systems. It is designed to provide reliable and accurate switching of electrical loads, such as lighting, at up to 30V DC. This article will provide an overview of the 4-1393306-6 automotive relay’s application fields and working principles.

The 4-1393306-6 automotive relay is used in many applications, such as fuel pump and engine control, engine starting, as well as lighting and other equipment. It is designed for use with 12-volt or 24-volt electrical systems, and is capable of switching electrical loads from 30V DC. The relay is designed for a range of 125,000-300,000 operations with a life expectancy of 18-36 months, depending on the application.

The 4-1393306-6 automotive relay consists of five pins arranged in a standard “T” configuration, two of which are labeled “Coil” and “Switch”. The coil pin is connected to an electrical power source, such as a battery, which supplies the energizing current to activate the relay when a voltage is applied. The switch pin is connected to a load, such as headlights or taillights. When the voltage is applied to the coil pin, a magnetic field is created which causes a switch mechanism to move, which in turn turns the power from the source on or off to the load.

The working principle of the 4-1393306-6 automotive relay involves a process of making and breaking an electrical connection through the relay. When voltage is applied to the coil pin, a magnetic field is created which pulls the internal switch mechanism to close the connection between the source and the load. This process is known as a "make" cycle. Once the voltage is removed, the switch mechanism moves back, returning the connection to its original state, and is known as a "break" cycle.

The 4-1393306-6 automotive relay is an essential component in many automotive applications. Its efficient and reliable switching of electrical loads makes it ideal for engine control, fuel pump and starting systems, and lighting. Its 5-pin design allows for easy installation and its high-quality construction ensures a long and reliable life.
