MOLEX / BRAD KK 254 Vertical Solid Header, 4 Way, Tin Plating
MOLEX / BRAD KK 254 4-way vertical solid header with friction lock. Tin-plated brass contacts, 2.54mm pitch.
The MOLEX / BRAD KK 254 Solid Header is a vertical, 4-way PCB connector designed for reliable wire-to-board signal applications. Featuring a friction lock for secure mating, this solid header ensures a stable connection in demanding environments where vibration or movement may occur.
Constructed with a durable nylon insulator in a natural (white) colour, the header is partially shrouded to protect the contacts during mating and unmating. The contacts are made from high-quality brass with tin plating, providing excellent conductivity and corrosion resistance. It is designed for through-hole straight mounting on printed circuit boards, ensuring a robust mechanical and electrical bond.
With a pitch spacing of 2.54mm and a single row of 4 contacts, this connector is part of the KK 254 6373 Series. Its compact dimensions (43mm height, 33mm width, and 15mm depth) and lightweight design (0.519 grams) make it suitable for space-constrained applications where both performance and size are critical.
