Automotive relays are essential aspects of any vehicle\'s electrical system, providing effective switching of electrical circuits to control a variety of functions. The G8NW-2 DC12 is a type of automotive relay manufactured by Omron specifically for use in automotive applications. It features highly reliable switching due to a core contact structure optimized for medium loads. This article will discuss the G8NW-2 DC12’s application field, as well as its underlying working principle.

Application Field of the G8NW-2 DC12

The G8NW-2 DC12 is designed for use in automotive systems. It is most commonly used in automobile ECUs and power windows, where it is responsible for switching electrical signals between components. Additionally, it can also be used to control door locks, wiper motors, and headlight dimmers. The G8NW-2 DC12 is also corrosion-resistant and vibration-resistant, making it suitable for use in harsher environments.

Features of the G8NW-2 DC12

The G8NW-2 DC12 has several features that make it well-suited for automotive applications. These include a compact size, an impressive cycle life of 200,000, and a wide range of operating temperatures, from -30 up to +105 Celsius. It also features a highly reliable switching capability, with a maximum contact resistance of 50 m +/- 10 m and a minimum break time of 0.1 ms.

Working Principle of the G8NW-2 DC12

The working principle of the G8NW-2 DC12 is based on a contact moveable type structure. This consists of a pair of movable plates, which are connected to a shuttle and moved by a magnet. When a current passes through the magnet, it produces an electromagnetic force, which causes the movable plates to open or close, depending on the polarity of the current. This action is responsible for switching the electrical circuit between its components.

In addition to the contact moveable type structure, the G8NW-2 DC12 also features a core contact structure, which is optimized for switching medium loads. This feature is designed to improve the performance and reliability of the relay, particularly under high vibration conditions. It also allows the G8NW-2 DC12 to effectively switch between a range of load currents, from 1.3A to 10A.

Conclusion

The G8NW-2 DC12 is an automotive relay designed for use in automotive systems. It is equipped with a contact moveable type structure designed for switching medium loads, in addition to providing reliable and corrosion-resistant operation. With its wide range of operating temperatures and its impressive cycle life of 200,000, the G8NW-2 DC12 is an excellent choice for automotive applications.
