Current rating segmentation highlights that pathways carrying between two and five amperes, those exceeding five amperes, and circuits below two amperes each call for tailored contact designs and insulation strategies to optimize electrical performance under varying load conditions.

Pitch considerations further distinguish sub-market dynamics, with connectors spanning one to two millimeters, those above two millimeters, and sub-one-millimeter pitches addressing diverse requirements for signal integrity and compact packaging. The number of positions, ranging from fewer than ten and configurations of 10 to 20 positions to assemblies exceeding 20 positions, influences connector footprint and mating complexity. Mounting style, whether surface mount or through hole, affects assembly workflow and mechanical robustness. Material selection for insulation-namely liquid crystal polymer, polyamide, and polyphenylene sulfide-dictates thermal endurance and dielectric behavior, while contact plating choices between gold and tin determine corrosion resistance and cost efficiency. Finally, locking mechanism preferences, whether friction lock or latch lock, directly impact mating force, retention security, and serviceability.
