3-644661-4 is a rectangular connector header assembly consisting of two parts: a 3-644661, which is a 4-position header, and a 646261 which is a 4--position crimp straight male pin. This type of connector is categorized as one of the various types of rectangular connectors in the market today.

Rectangular connectors are broadly used in a variety of applications due to its small size, relative robustness and ease of use. These connectors are commonly used in communication, automotive, industrial and consumer electronics applications. Internally, the connectors feature contact flat blade, cross slot, pin and specific combinations of them. Externally, they take various shapes such as rectangular, board-to-board, mezzanine, light pipes, board-to-wire, RJ-12 and many others.

3-644661-4 is used mostly in automotive and industrial applications, where the need for quick, reliable, and secure connections is key. This application requires that the connections be made with easy connection positioning and a secure fastening mechanism. This rectangular connector header not only provides secure connections but also can be mass-terminated with less effort.

In terms of its working principle, 3-644661-4 consists of a 3-644661 housing, a mating plastic face, two selectable contact positions and a 646661 male pin. The 3-644661 housing is a plastic Greycroft housing with two opposing connector faces. It has two plastic contact positioning posts and two selectable contact terminals on each side. The mating plastic face is attached to the 3-644661 housing allowing both contact positions to be engaged or disengaged depending upon the application. The 646261 male pins are attached to the contact terminals via an interference fit. When the pins and terminals are engaged, an electrical path is completed allowing for efficient signal transmission.
