High precision 2.54mm double end stepped machined pin header with different pin diameter (Ø0.6mm / Ø0.46mm), 180 degree straight, 1-40 positions customizable. Premium PPS housing, stable board to board connection for industrial electronic PCB assembly.

This professional-grade double-end machined round hole pin header features different diameter pins on both ends: upper pin Ø0.6mm, lower pin Ø0.46mm. Unlike general same-diameter dual pin headers, this stepped different-size design provides targeted plugging and soldering performance, perfect for space-limited and high-precision PCB board-to-board stacking applications.

Manufactured with solid turned machined pins (not cheap stamped pins), delivers ultra-low tolerance, zero burr and perfect alignment accuracy. Pin count fully customizable from 1 Pin up to 40 Pins, 180° straight vertical structure with standard universal 2.54mm pitch.

Adopts high temperature resistant PPS insulator and standard gold plating, offers outstanding anti-oxidation, stable electrical conductivity and long operating life. Widely applied in industrial controllers, communication equipment, medical electronics, smart home and automotive peripheral devices, all custom specifications are supported.
