EN6049 – HARNESS PROTECTIONS

EN6049 – Performance products for demanding environments

The EN6049 standard defines the general characteristics, qualification and requirements for the protection sleeves in meta-aramid fibres for aircraft harnesses.

This specification offers a comprehensive range of high quality sleeving and shielding solutions for civil and military markets.

The EN6049 has two options available depending on the selected designation: wrappable or expandable.

The expandable and wrappable products are tough, lightweight and are used to protect cable assemblies, hoses and wire harnesses from chafing, cutting and abrading.

On the first hand, the expandable version enables each size to expand to fit several diameters and application shapes.

On the other hand,the self-wrapping version offers a wrappable design which is more suitable for quick and easy maintenance.

This version allows users to easily install,modify and remove wire and cable bundles without disconnecting all the components.

Depending on the applications or area requirements ,the EN6049 can be a perfect solution instead of using convoluted conduits.

The goal is to provide bundling and protection against abrasion, high temperature, electrical arc tracking ,fire protection, EMI shielding.

The standard color is « olive green » however a few colours are available upon request including orange for test benches.

It is important to take the constraints into account and then the bundle diameter ( a diameter tape measure is recommended for optimized accuracy).

Some accessories are also recommended to close and to make the installation of the self-wrapping sleeve easier :

  • The « Insertion tool » to ease installation of the cables in the self-wrapping sleeve
  • The « Cable ties » ( NSA935401 , ASNE0043 or « Lacing tape » ( NSA8420 ) are used to secure the closure of the sleeve
  • The « Metallic cable ties » ( ASNE0805 or M85049/128) are used for EMI shield termination on banding backshell

  • The « Banding split Rings » ( ABS0940 or M85049/93) are used to protect cables from being damaged when the «Metallic cable tie »  is fitted

  • The « Silicone tape » (ABS5334 or ASNA5107) is used to cover Band-it for cut protection and also avoid cables and banding split ring from moving.
