What this 4-position shrouded header does for your board
The 1734595-4 is a 4-position, single-row, shrouded header from TE's High Performance Interconnect (HPI) series. Its 1.00 mm pitch and surface-mount termination keep the footprint tight for signal-level wiring in automotive, industrial, and medical assemblies. The full 4-wall shroud protects the male pins during mating and guides the receptacle into alignment — a detail that matters when the connector is buried in a harness bundle or fed by a pick-and-place machine.
Pitch, position count, and current — the BOM-fit check
At 1.00 mm pitch and 4 positions, this header mates with a matching 1.00 mm pitch receptacle carrying 4 circuits. The tin-on-tin contact finish (120.0 µin on both mating and post sides) is a cost-effective choice for moderate mating-cycle applications — expect reliable contact resistance through several dozen cycles in a clean environment.
Mating and termination — what it takes to land this header
The pick-and-place feature allows automated assembly without a secondary hold-down.
