Introduction

Rectangular Connectors - Headers, Male Pins, are electrical connectors primarily used to connect two points of different power or signal levels. These connectors are typically used in computers and industrial control systems, as well as the medical and telecommunications industries, where it is beneficial to be able to quickly and easily connect and disconnect signals and power. One of the most popular rectangular connectors is the 3-641127-9 series, which offers users a robust and durable design perfect for a variety of applications.

Design

The 3-641127-9 series is a standard-sized rectangular connector featuring a unique design. It features eight pins arranged in two rows. Each pin is gold-plated for better conductivity and environmental protection. The connector also features a black thermoplastic hood that provides a secure seal when two connectors are mated. This hood also helps protect the pins from dust and debris, making it ideal for applications in dirty or dusty environments.

Features

The 3-641127-9 features several features that make it an excellent choice for a variety of applications. It is rated for up to 6.5 amps and operates over a temperature range of -55ºC to +125ºC. Additionally, it is UL and CSA approved, meaning that it is suitable for use in products where safety is paramount. The connector also features a crimp termination style, meaning that it is easy to install and securely hold the pins in place.

Another unique feature is the three-point mounting system. This system allows the connector to be securely mounted to a variety of surfaces, such as printed circuit boards or panel walls. Additionally, the connector has dual rows of pins, meaning that it can easily be daisy-chained with other 3-641127-9 connectors, allowing for easy scalability of a system of connected devices.

Applications

The 3-641127-9 series is primarily used in computers and industrial control systems. It is often used in applications where large amounts of power must be quickly and easily connected and disconnected, such as in the printing industry. Additionally, due to its robust design, it is often used in applications where environmental protection is required, such as in the medical and telecommunications industries.

In addition to computers and industrial control systems, the 3-641127-9 series is also used in a variety of other applications. Its robust design makes it perfect for automotive applications, where it is used to connect throttles and other sensor systems. Additionally, it is often used in solar cell applications, as its black thermoplastic hood ensures that the pins remain free from dust and debris. Finally, the 3-641127-9 series is also used in audio equipment, as its crimp termination style ensures that the audio signal is transferred without any signal degradation.

Working Principle

The working principle of the 3-641127-9 series is simple. When two connectors are mated, the pins of each connector are connected. This allows for an electrical connection between the two components, allowing current to flow. This connection is made more secure by the black thermoplastic hood, which helps to protect the pins from dust and debris and keeps the connector from being disconnected. Additionally, the three-point mounting system ensures that the connector is securely mounted and does not become loose or disconnected.

Conclusion

The 3-641127-9 series is an excellent choice for a variety of applications. It features a robust design with a black thermoplastic hood for environmental protection and a three-point mounting system for secure mounting. Additionally, its crimp termination style makes it easy to install and its dual rows of pins makes it easy to daisy-chain with other connectors. All these features make the 3-641127-9 series the ideal choice for applications in computers and industrial control systems, as well as the medical, telecommunications, automotive, and solar cell industries.
