Our 1.27mm pitch 20‑pin SMT pin header & socket (male‑female mating pair) is a high‑density surface‑mount board‑to‑board interconnect solution, also known as a 0.050 inch pitch connector. Designed for reflow soldering, fully compatible with SMT pick‑and‑place automatic assembly. This 20‑position dual‑pair set delivers compact footprint, stable signal transmission, and consistent mechanical performance, widely adopted for space‑limited PCB stacking and modular electronic systems. Available in male pin header and female socket for mutual mating; custom pin counts, plating, polarization, and tape‑&‑reel packaging are supported for OEM & ODM projects
