Huber+Suhner SPUMA_400-RS-FR is a high-quality flexible RF coaxial cable featuring a 50 Ω characteristic impedance and an outside diameter of 10.25 mm. Designed with a black thermoplastic polyurethane (TPU) jacket, this cable is flame retardant and railway qualified, making it ideal for use in demanding industrial, transportation, and communication environments.
The cable supports operating frequencies up to 6 GHz, ensuring reliable signal transmission with minimal attenuation of 0.39 dB. It operates reliably in temperature extremes from -40°C to +85°C, suitable for harsh environments.
The construction includes a stranded copper center conductor for excellent electrical conductivity, and an outer conductor made of aluminum, copper, and tin plating. The insulation is foamed polyethylene (SPE), providing high insulation resistance of at least 1,000,000 MΩm for signal integrity.
The flame retardant TPU jacket enhances durability and safety, meeting stringent standards such as NFPA-130, IEC 60332-3-25, EN 61034-2, EN 60332-1-2, EN 50305, EN 45545-2, as well as European RoHS and REACH compliance directives.
This cable is unterminated, offering flexibility for custom connector applications in electrical, automation, railway, and networking installations where robust coaxial cabling is required.
The product is made in Switzerland, reflecting precision engineering and quality materials. With a weight of approximately 14.2 kg per 100 meters, it balances durability with manageable installation weight.
This cable delivers reliable high-frequency performance up to 6 GHz. It operates in a wide temperature range from -40°C to 85°C. Flame retardant TPU jacket ensures safety and durability. Complies with multiple international fire and safety standards.
Unterminated design allows for customized termination approaches. Manufactured with stranded copper conductor and foamed polyethylene insulation. Ideal for railway, industrial, and communication applications. Produced in Switzerland following strict quality controls.
