22-12-4042

The Molex 22-12-4042 is a KK 254 series PCB header designed for reliable wire-to-board interconnections in a wide range of electronic applications. Featuring a 2.54mm pitch and 4 circuit configuration, this right-angle through-hole header enables compact PCB layouts with side-entry cable routing. Part of the widely adopted KK interconnect system, the connector includes a friction lock mechanism to ensure secure mating with compatible housings. Its through-hole termination provides strong mechanical retention, while gold-plated contacts enhance electrical performance and long-term reliability. With a current rating of up to 4A per contact and a maximum voltage of 500V, this header is suitable for both signal and moderate power applications across industrial and consumer electronics.
