Connectors Interconnects

Connectors and interconnects are the backbone of every electronic system, enabling reliable electrical and mechanical connections between components, boards, and subsystems. This category spans board-to-board, wire-to-board, wire-to-wire, FFC/FPC, circular, rectangular, coaxial (RF), D-sub, USB, HDMI, and terminal block connectors. Key selection parameters include pin count (from 2 to 500+), pitch (0.4mm to 5.08mm), current rating (signal-level mA to 100A+ power), voltage rating, mating cycles, ingress protection (IP rating for harsh environments), and operating temperature range. Popular manufacturers: TE Connectivity, Molex, Amphenol, JST, Hirose, Samtec, Phoenix Contact, and Harwin. Whether selecting for consumer wearables, industrial machinery, automotive harnesses, or aerospace avionics, matching the connector to mechanical constraints and electrical requirements is critical for long-term reliability.
