5-position right-angle SMT header for board-edge harnesses
The 1734709-5 is a 5-position, single-row header from TE's High Performance Interconnect (HPI) series, on a 1.00 mm pitch. The housing is fully shrouded on all four walls, protecting the square male pins from damage during blind mating and preventing accidental shorting against adjacent components.
Signal-level ratings with a wide environmental envelope
Rated at 1 A per contact and 50 V, this header is intended for signal interconnect, not power distribution. The tin-on-tin contact finish (120.0 µin on both mating and post sides) is cost-effective for moderate mating-cycle applications — expect a few hundred cycles before wear-through, typical for harnesses that mate during assembly and rarely disconnect in the field. The part is explicitly listed for Automotive, General Purpose, Industrial, and Medical applications — not just a marketing tag; the material set and plating are chosen to survive those environments.
