Shielded vs unshielded connectorsA shield only improves electromagnetic compatibility when it is continuous from cable to housing to panel, with low impedance at the frequencies that matter. This article explains how foil and braid shields work, what transfer impedance measures, why 360° termination outperforms pigtails, how to approach shield grounding, and when an unshielded connection is the better engineering choice. - 02

Contact resistance and connection reliabilityContact resistance is set by a few microscopic contact spots and the films that cover them, not by the apparent contact area. This article explains constriction and film resistance, the roles of normal force, wipe and plating, how contact resistance is measured, and how it links to temperature rise and current derating.
