Discrete Wire Cable Assembly
A discrete wire cable assembly consists of multiple individual wires that are assembled and terminated with connectors to conduct power and signal transmission between distinct equipment components.
Overmolded Cable Assembly
An overmolded cable assembly is an integrated cable unit with plastic overmold shielding on the cable and connector interface, which enhances structural durability and provides superior protection against harsh environmental elements such as humidity and dirt.
Flat Cable Assembly
Flexible flat cables commonly feature standard pitches of 0.635mm, 1.0mm and 1.27mm, and are typically terminated with IDC connectors, D-sub connectors and crimp-style terminals.
