Overview

The TE Connectivity 504385-E PCB Mount Header is a precision-engineered, 4-position board-to-board connector designed for compact electronic assemblies requiring reliable, high-density interconnects. This vertical-mount header features a 1.27mm (0.05 inch) centerline pitch, fully shrouded housing, and gold-plated contacts for superior electrical conductivity and corrosion resistance. Engineered for surface mount technology (SMT), the 504385-E simplifies PCB assembly while maximizing space efficiency in high-density applications. The ERNI MicroBridge technology ensures robust mechanical stability and precise alignment, reducing misalignment risks during mating. With a compact footprint and gold-plated contacts rated for low contact resistance, this header is ideal for industrial automation, automotive electronics, telecommunications, and consumer devices where signal integrity and durability are critical. The fully shrouded design provides mechanical protection against mating/unmating stresses, while the surface mount termination ensures consistent solder joint reliability. Compatible with standard 1.27mm pitch board-to-board connectors, this header supports high-speed signal transmission with minimal signal loss. Typical applications include embedded systems, power supplies, sensor interfaces, and modular electronics where space-constrained designs demand dependable interconnect solutions.
