Shielded Individual Cables: Temperature Range -40°C to 105°C

Component Specifications

Definition

Shielded individual cables consist of a conductive core (typically copper or aluminum) surrounded by insulation, an electromagnetic shield (braided, foil, or combination), and an outer jacket. They are designed to minimize electromagnetic interference (EMI) and radio frequency interference (RFI) in sensitive electronic and electrical systems, ensuring signal integrity and reducing noise in industrial environments.

Working Principle

The shielding layer (usually made of conductive materials like copper or aluminum) acts as a Faraday cage, diverting electromagnetic interference away from the inner conductor. This prevents external EMI/RFI from affecting signal transmission and reduces electromagnetic emissions from the cable itself.

Materials

Conductor: Annealed copper (stranded or solid), Insulation: PVC, XLPE, or PTFE, Shielding: Braided copper, aluminum foil, or composite foil/braid, Jacket: PVC, polyurethane, or thermoplastic elastomer.
