Introduction

The 3-641208-2 is a component part belonging to the family of rectangular connectors, and is classed under the sub-heading of headers, male pins. Rectangular connectors are utilized in a variety of products and systems, ranging from automotive applications, switches, and displays to telecommunications.The 3-641208-2 is no different. It is a one-piece construction for rectangular connectors and comes in a number of different housing sizes and terminal textures for installation onto a printed circuit board.

Uses

The 3-641208-2 is primarily used in systems that require high-density connections in limited spaces. The versatility of this product ensures that it can be utilized in multiple situations, whether mounted on a board or through-hole tapped.Additionally, its universal usage and compatibility with different rectangles and backshells make it a useful component for a diverse range of applications. These include audio/visual equipment such as telecom switches, game consoles, or entertainment systems, and automotive electronics such as airbag lifts, HVAC systems, and navigation systems.

Features

The 3-641208-2 is a robust device, offering a number of features that make it suitable for use in many applications. It is a polarizing component that utilizes a metal ferrule, which provides a barrier against dust and debris. Its one-piece construction further enables it to be integrated into circuits quickly and easily, with no wiring necessary.The 3-641208-2 also features removable terminals, allowing it to be serviced without the need to sacrifice assembly-line production or line output. This flexibility results in better use cases, enabling the headers to be used in multiple situations across a range of products and devices.

Connector Types

The 3-641208-2 is a single-row, five-terminal rectangular connector header. It is housed in two forms: the 5x2.00mm and 5x2.50mm. It is offered in two housings: a 1.50mm or 2.00mm drilled version. The board-mounted terminal option also comes in three terminal textures, namely Lead-free (RoHS), Tin, and Lead Tin-Plated. The conductor termination consists of two styles, being 2.00mm and 2.50mm of diameter and plain or tin-plated. The insulation is designed for 0.85mm to 1.15mm thick FR4 circuit boards with a grey, molded UL94V-0 or UL94V-2 polyamide housing. The contacts feature a four point contact system, with crimp termination.

Working Principle

When the 3-641208-2 is in place, it operates by making contact through the four points of contact. When a circuit is closed, a small voltage is created which causes the two terminals to be attracted to each other, forming a connection. This connection allows the current to flow through the system, which powers the relevant device or component.When the connection is broken, either by manually disconnecting the pins or operating in hazardous conditions, the contact points will separate, which will cause the current to no longer flow. This is an important safety feature which serves to protect the circuit from making contact with any potentially hazardous elements.

Conclusion

The 3-641208-2 is a versatile component for utilizing in a variety of space- and power-constrained applications. Its wide range of features, coupled with its compatibility with different terminals and back shells, make it a useful device for a diverse range of applications. Whether used for automotive electronics, audio/visual equipment, or telecommunications, its combination of features and one-piece construction make the 3-641208-2 an appealing choice for densely populated designs where reliability and accuracy is required.
