BRAIL Cat5E cable is intended for permanent onboard Ethernet wiring in rail and other public-transport vehicles. The range includes four-core and four-pair constructions for equipment connections such as passenger information and multimedia systems. Foil and tinned copper braid screens surround the conductor assembly, with electron-beam crosslinkable insulation and sheath compounds.

Three listed constructions: 4 × 0.5 mm², 4 × 22 AWG and 4 × 2 × 22 AWG.
Flexible copper conductors with plating specified for each construction.
Nominal overall diameters of 8.3, 7.25 and 12.6 mm respectively.
Select the cable code and core arrangement to match the Ethernet equipment and connector pinout. The four-core and four-pair versions have different dimensions and conductor descriptions, so the complete designation belongs on the cable schedule. The listed minimum bend radius is 6 times the overall diameter; the temperature range is −40°C to +90°C.

Which cable codes are listed?
BRAIL Cat5E-4C0.5S, BRAIL Cat5E-4C22A and BRAIL Cat5E-4P22A.
How do the four-core and four-pair versions differ?
The four-core versions contain four individual conductors. The four-pair version contains eight conductors arranged as four pairs around a PE filler.
Are all versions described with the same conductor plating?
No. The four-core 0.5 mm² version specifies tinned copper, the four-core 22 AWG version specifies silver-plated copper, and the four-pair version specifies tinned copper.
What screening is used?
Plastic-laminated aluminium tape and a tinned copper braid, with plastic separator tape.
What installation duty is this range intended for?
Permanent fixed onboard wiring, with cable supports and connectors selected for the particular vehicle installation.
