Board-edge signal interconnect for tight spaces
The 5-1775444-6: This 6-position, single-row header from TE's HPI series mates with a wire-to-board receptacle to carry signal-level current in automotive, industrial, and medical equipment. The right-angle SMT orientation places the connector parallel to the board, saving z-height at the board edge for enclosures with tight clearance. Full 4-wall shrouding protects the square male pins from damage during blind mating and guides the receptacle into alignment — a practical feature when the connector is not directly visible during assembly.
What the 3 A tin contact rating means for your build
Rated 3 A per contact at 25 °C ambient, with tin-on-tin mating surfaces. Tin is cost-effective but wears faster than gold under repeated mating — expect a lower mating cycle life, typically under 50 cycles before contact resistance rises. In a low-cycle application like a one-time assembly or infrequent service connector, tin is a practical choice. The 100.0 µin tin thickness on the mating face is standard for the class; the contact finish on the solder tail is also tin, compatible with lead-free reflow profiles.
