The TE Connectivity AMP-HDI 532448-3 is a fully shrouded, board-to-board connector header designed for high-density PCB interconnection in space-constrained applications. This 128-position, 4-row pin assembly delivers reliable signal and power distribution across demanding environments including aerospace, military, industrial instrumentation, and data communications systems. The vertically oriented header features press-fit through-hole termination with four-beam phosphor bronze contacts plated in gold, supporting a maximum contact current rating of 3 A and insulation resistance of 4 MΩ. With a 2.54 mm centerline pitch and 6.35 mm post length, the connector integrates into standard PCB layouts while maintaining the mechanical stability required for mission-critical applications.
