Rectangular Connectors - Headers, Male Pins - 499141-4 Application Field and Working Principle

Rectangular connectors are widely used in the industries to transmit electrical and electronic signals between different components. The rectangular connectors are compatible with several types of interfaces including PCB header, male pins, etc. One of these connectors is 499141-4. This connector is used for power and signal conduction of automotive head and taillight control systems. With its 4 high-quality pin contacts, the 499141-4 connectors provide more reliable transmission of signals compared to other generic connectors. This is due to its ability to reduce electromagnetic interference (EMI), which is often caused by electrical components that create unwanted noise in other electronics. Moreover, the 499141-4 connectors are also able to reduce fatigue due to its contact spring clamping structure, which helps spread forces evenly and continuously over the entire connection. The 499141-4 connector is designed for use with wire-to-wire, wire-to-board, and board-to-board connectivity. It features a 4-pin contact layout with Nickel Plated brass-battery contacts for reliable signal retention and low contact resistance. The temperature rating for the 499141-4 connector is 125°C, which is suitable for use in automotive applications. In addition, the 499141-4 connector also features an ergonomic design, which allows for easier and safer installation. The working principle of a 499141-4 connector is fairly simple. It consists of two parts that are connected together with a pin or a slot. The first part is a connector body designed to fit into a specific mounting or assembly, while the second is a contact housing unit. The contact housing has four connection points: three for the power conductors and one for the ground. When the connector is inserted into the mounting, the contact springs inside the housing make contact with the power conductors. This ensures that electrical signals are transmitted without any interruption. In conclusion, the 499141-4 connectors are reliable components often used in automotive lighting systems. This type of connector allows for efficient and reliable signal transmission between two components while also providing protection from EMI. Moreover, the 499141-4 connector features an ergonomic design for easy installation and a temperature rating of 125°C for safe usage. With its reliable performance, the 499141-4 connector is the perfect choice for automotive lighting applications.
