In today's era of rapid development in high-speed signal transmission and precision electronic equipment, ultra-fine coaxial cable bundles (micro coaxial cable) have become a popular choice in fields such as smartphones, medical imaging, industrial automation, and consumer electronics due to their excellent anti-interference properties, flexibility, and ultra-small size. Among these high-performance cable bundles, PTFE sheath is almost a standard feature. This article will introduce why PTFE sheath has become the preferred choice for ultra-fine coaxial cable bundles, as well as its ideal combination with the JAE FI-JW40C connector.
What is an ultra-fine coaxial beam?
Micro coaxial cable is a compact high-frequency signal cable with an extremely small diameter. It usually consists of an inner conductor, insulating layer, shielding layer, and sheath, featuring small size, light weight, low signal attenuation, and strong anti-interference capability.
This kind of cable is widely used inside devices such as smartphones, tablets, medical endoscopes, drones, and security cameras, realizing high-speed and high-stable signal transmission.
PTFE sheath: The ideal choice for ultra-fine coaxial cable束
PTFE (Polytetrafluoroethylene), due to its excellent comprehensive properties, is known as the "King of Plastics." Compared with ordinary PVC or PE sheath materials, PTFE has the following advantages:
Strong high-temperature performance: Can be used for a long time under an environment of -65℃ to +260℃, suitable for high-temperature working conditions.
Excellent chemical stability: Acid and alkali resistance, oil resistance, corrosion resistance, ensuring the long-term reliability of the cable harness.
Extremely low coefficient of friction: convenient for wiring in narrow spaces, reducing wear.
Excellent insulation performance: low dielectric constant, small signal transmission loss, and stable high-frequency signals.
Good flame-retardant properties: self-extinguishing when exposed to fire, enhancing equipment safety level.
Due to these characteristics, PTFE sheath has become the preferred choice for extremely thin coaxial cable assemblies in high precision and high reliability applications.
Section 3: JAE FI-JW40C connector combined with extremely thin coaxial cable assembly
In ultra-fine coaxial cable systems, a suitable connector is crucial. The JAE FI-JW40C connector has the following characteristics:
• Supports ultra-fine coaxial cables with a pitch of 0.3-0.5mm.
Ultra-thin design, saving internal space of the device.
Excellent EMI shielding capability to ensure high-speed signal transmission.
• Simple clip-type connection, easy for assembly and maintenance.
• Meets stringent vibration and impact testing standards.
Combining PTFE sheathed ultra-fine coaxial cable assemblies with JAE FI-JW40C connectors provides an efficient, stable, and compact internal wiring solution for equipment, enhancing product performance and reliability.
PTFE sheath becomes the first choice material for extremely thin coaxial cable束 due to its high temperature resistance, strong chemical stability, low friction coefficient, excellent insulation performance, and flame-retardant characteristics. When paired with JAE FI-JW40C connector, it can realize a high-density, high-reliability, and high-performance internal wiring scheme.
