Flat-ribbon cable can withstand high-temperatures

Temp-Flex FEP flat-ribbon cable meets the MIL-Spec requirement for M49055/11 & M49055/12 for harsh environment applications such as those found in aircraft avionics and industrial equipment.

Unlike competitive PVC (Polyvinyl Chloride) and TPE (Thermoplastic Elastomers) products, Molex Incorporated offers extruded FEP (Fluorinated Ethylene Propylene) dielectric insulation material for a high-performance ribbon cable that can withstand exposure to chemicals, extreme temperatures, abrasions and flexure.

“Signal failure has long been prevalent in military, aerospace and industrial equipment applications due to the limited capability of PVC and TPE cables, which can degrade after repeat exposure to harsh conditions,” said Jeet Sanyal, engineering manager, Molex Incorporated.

“Temp-Flex FEP cables were specifically designed for the most severe environments, yet they remain extremely flexible, making them suitable for today’s smaller more rugged applications including flight data recorder boxes, missile systems and robotics found in manufacturing plants across multiple industries.”

Temp-Flex FEP Flat-Ribbon Cables are durable in temperatures ranging from -65 to +200°C and they are resistant to acids, alcohols, aldehydes, bases, esters, hydrocarbons (aliphatic, aromatic, and halogenated), ketones and oxidising agents.

An extruded cable encapsulates each conductor with insulation that will not delaminate, while the low-loss dielectric constant (2.1) ensures the optimum signal transmission with minimal loss. The cables can be mass terminated using a conventional Insulation Displacement Termination/Connector (IDT/IDC) technology for efficiency and cost-savings.
