Molex / Brad KK 254 7478 Wire-to-Board Pin Header, 2.54mm, 2 Contact

The Molex / Brad KK 254 7478 Pin Header is a premium, right-angled connector designed for reliable wire-to-board interfacing in demanding signal applications. Part of the trusted KK 254 connector system, it features a high-temperature nylon housing for durability and stability in various operating environments. The robust construction includes polarising ribs and back walls on the housings, ensuring correct, foolproof mating and preventing accidental reverse insertion during assembly.

For a secure physical and electrical connection, this header employs a friction lock mechanism with integrated ramps on the housing, which provides a firm, vibration-resistant hold when mated with its corresponding receptacle. The contacts are crafted from brass and finished with gold plating, ensuring excellent conductivity, low contact resistance, and superior corrosion resistance for long-term reliability. The terminals also feature locking tangs for added retention within the housing.

Designed for through-hole PCB mounting, the right-angle configuration allows for compact, space-saving designs where board space is at a premium or where a horizontal connection is required. The connector is Reflow Process Compatible (RPC), making it suitable for modern, automated soldering processes, while the reflow matte tin plating on the PCB tails enhances solderability. The shrouded design offers additional protection for the pins and aids in guiding the mating connector.
