The AMPXL cable comes from the latest generation of UTP twisted pair cables. Its external diameter has been reduced to 5.0 mm, which considerably facilitates insertion of the cable into ducts and pipes. Special insulation material makes it easier to attach RJ-45 connectors.
Main features of AMPXL UTP cat 5e cable:
highest-quality materials, strict technological discipline confirmed by a 15-year quality guarantee,
parameters far exceeding the requirements for Category 5+ twisted pair cables
preliminary quality control of materials and thorough tests of the final product,
meter markers, deviation less than 0.5%,
solid wires of 0.50 mm diameter (24 AWG),
wire insulation made of homogeneous, colored PE; outer diameter: 0.88 mm; colors: white-green/green, white-orange/orange, white-brown/brown, white-blue/blue,
insulated wires twisted in pairs of 1.8 mm diameter,
pairs twisted together, outer diameter of ca. 4.0 mm,
sheath made of gray/ blue PVC, of 5.0 mm diameter.
The AMPXL UTP cat 5e LAN cable is manufactured in compliance with:
IEC 61156-6, ISO/IEC 11801, ANSI/TIA/EIA-568-B, yd/t1019-2001 standards.
The AMPXL UTP cat 5e cable can be used in a wide temperature range: -20°C...+70°C, and installed between 0°C and +50°C. The minimum bending radius factor (radius to diameter ratio) is 8.
