Rectangular Connectors - Board Spacers, Stackers (Board to Board)

Category Introduction

Rectangular header type connectors are designed to connect circuits on one PCB to circuits on another providing insulation and board spacing. They are selected by pitch (distance between pin centers), stack height, and the number of positions and rows. They are typically soldered in place, with surface mount and through-hole versions available in gold, tin and tin-lead options.
