20-Pin JST XH 2.54mm Top Entry Vertical Header – PCB Mount Through-Hole

The 20-Pin JST XH 2.54mm Top Entry Vertical Header is a straight through-hole PCB connector designed to securely mate with standard 20-pin JST XH female wire housings. Featuring an integrated polarization shroud that physically prevents reverse insertion, tin-plated brass pins for excellent solderability, and robust through-hole anchoring for repeated plug-unplug cycles, it is ideal for complex multi-axis automation mainboards, high-resolution display and keypad interfaces, graphic LCDs, touch panels, and high-density CNC or industrial controller frameworks.
