Molex KK 254 Right Angle Header 4 Way Friction Lock Tin Plating
Molex KK 254 4-way right-angle PCB header with friction lock and tin plating. High-temperature nylon for signal wire-to-board applications.
The Molex / Brad KK 254 Solid Header is a reliable wire-to-board connector engineered for secure signal applications. Featuring a right-angle, through-hole termination type, this 4-way PCB header is designed to provide a stable and space-efficient connection on your circuit boards. With a pitch spacing of 2.54mm, it is perfectly suited for standard electronic layouts.
Design and Security Features
This connector system incorporates a robust friction lock mechanism alongside friction lock ramp housings, ensuring a secure mate and preventing accidental disconnection during operation. Additionally, polarising ribs on the housings and polarising back walls are included to prevent mismating, while locking tangs on the terminals provide secure retention within the housing.
Material and Compatibility
Built to withstand demanding manufacturing processes, the housing is constructed from high-temperature nylon and is fully Reflow Process Compatible (RPC). The brass contacts feature reflow matte tin plating, offering excellent solderability and conductivity for consistent performance. The connector shroud is partially shrouded, providing an extra layer of protection for the contacts.
