The TE Connectivity 1-917541-3 is a 4-position, single-row shrouded header in the Dynamic D-5200 series, designed for board-to-cable/wire power interconnects in general-purpose and industrial equipment. The 10.16 mm pitch provides generous creepage for the 630 V rating, while the 30 A per-contact current capacity puts this squarely in the power distribution class — not a signal header. Gold plating on the mating contacts (30.0 µin) supports repeated mating cycles in corrosive or field-service environments, and the tin-plated solder posts keep the board-level termination cost-effective.
Mounting and Retention
Right-angle through-hole termination places the mated cable parallel to the PCB — a common layout for board-edge power entry where the harness exits along the enclosure wall. The board lock anchors the header during wave solder and resists shear from cable strain. A detent lock on the shroud provides audible feedback when the mating receptacle is fully seated, which matters in assembly lines where a partial mate is a latent failure.
Mating and Termination
This header mates with the corresponding Dynamic D-5200 receptacle housing that accepts tab contacts. The 4-wall shrouding protects the gold-plated tabs from bending during handling and guides the mating half into alignment. The detent lock holds the pair together without additional hardware — a field-serviceable latch that releases with a pull. Termination is solder to the PCB; the wire side uses crimp contacts in the receptacle.
