AFPF Oil-Resistant High Temperature Shielded Cable is designed for signal transmission and instrumentation circuits operating in electrically noisy and chemically aggressive environments. Constructed with fluoroplastic insulation, a tinned copper braided shield, and a fluoroplastic outer sheath, the cable provides reliable resistance to high temperatures, industrial oils, chemicals, and electromagnetic interference (EMI), making it suitable for demanding industrial automation and process control applications.

Cable Construction

Rather than relying on a single protective layer, AFPF cable combines multiple materials to improve electrical reliability and environmental resistance.
