Cable Sleeve DeLOCK 20938 Grey Copper Polyester 1 cm 10000 mm

The DeLOCK 20938 cable sleeve is a braided protective sleeve made of polyester and copper braid with a nominal diameter of 1 cm and a length of 10000 mm. It is designed for shielding and bundling exposed cables or electrical conduits and is suitable for use in a wide temperature range from -50 to 150 °C. The sleeve’s construction combines abrasion-resistant polyester with a conductive copper braid to reduce electromagnetic interference and protect cables from environmental damage.

Advantages

The combination of polyester and copper braiding provides both mechanical protection and electromagnetic shielding. Polyester offers high abrasion resistance and dimensional stability, while the copper braid delivers flexibility and conductive shielding against interference. The sleeve is stretchable to accommodate multiple cables or wires of different diameters and resists bending and weather-related wear.

Suitable for

• Bundling and organizing power and signal cables
• Shielding cables from electromagnetic interference (EMI)
• Protecting exposed wiring in industrial or outdoor environments
• Routing harnesses in automotive, telecommunication, and electronic assemblies

How to use

Slide the braided sleeve over the cable bundle or feed individual cables through the sleeve during assembly. If necessary, expand the sleeve slightly to accommodate broader bundles, then allow it to contract for a snug fit. Secure the sleeve ends with heat-shrink tubing, cable ties or tape where required to prevent fraying and to fix the sleeve position.

Recommendations

For optimal shielding performance, ensure the copper braid makes electrical contact with the equipment chassis or a grounding point where required. Avoid sharp bends that could locally stress the braid; trim frayed ends cleanly and seal with adhesive tape or heat-shrink to maintain mechanical protection.
