71609-309LF

Rectangular Connectors - Headers, Receptacles, Female Sockets

71609-309LF is a rectangular connector, usually consisting of two elements: a header and a receptacle. The connector has an open frame construction and is especially designed for wire-to-board connections. It offers superior electrical performance, including current ratings of up to 3.4A.

Application Field

71609-309LF is used in the electrical and automotive industries pertaining to low power wired connection applications. It is commonly used for connecting light control products, rack units, and circuit boards. Besides, this connector is suitable for a range of automotive applications such as interior LED lighting, communication systems, body control systems, and other automation systems.

Working Principle

This rectangular connector has a two-piece construction with a header and a receptacle. It features a male header with 4.5mm and 4.2mm centerline pitches, as well as a male receptacle. The two parts of the construction each feature terminating post legs which ensure accurate mating and secure contact over a range of temperatures. The legs are also press-fit units which guarantee secure holding of the contact and reliable grounding.

The contact post legs are designed to have low insertion and withdrawal force which are usually compromised when mating with traditional crimp type contacts. In addition, the contact post legs are internally isolated with a damper function. When the posts reach the mating area, the internal isolator dampens the contact against stress forces caused by insertion and withdrawal.

Conclusion

In conclusion, 71609-309LF is a rectangular connector specially designed for wire-to-board connection in low power applications. It is used for light control products, circuit boards, and other automotive systems. The two-piece connector features contact post legs that have low insertion and withdrawal forces, and are internally isolated with a dampening function.
