## Summary description

Rittal AS 4050.784 ferrule sleeves (crimp wire end terminals) made of copper with polypropylene insulation. Colour: grey. Nominal outer diameter 4.8 mm, length 12 mm. Supplied in a pack of 100, suitable for terminating and protecting stranded conductors, improving connector reliability and ensuring secure crimped connections in control cabinets and electrical installations.

## Long description

Rittal AS 4050.784 ferrule sleeves are copper crimp wire end terminals with a polypropylene insulating collar, designed for reliable termination of stranded conductors in electrical installations and control cabinets. The sleeves have a nominal outer diameter of 4.8 mm and a length of 12 mm, supplied in a pack of 100 and finished in grey. They provide a consistent crimping interface that improves contact reliability and protects conductor strands from fraying and damage during connector insertion.
Advantages
These ferrule sleeves combine a copper conductive body with a polypropylene insulating collar to offer both electrical conductivity and mechanical protection. The uniform dimensions and consistent wall thickness support repeatable crimps, reducing the risk of loose connections and improving long-term contact stability. Supplied in a pack of 100, they simplify stocking and small-batch installation work. The plastic collar also aids in handling and insulation at the termination point.
Suitable for
 Termination of stranded copper conductors in control cabinets and distribution panels
 Crimping onto conductors before insertion into terminal blocks, relays, and connectors
 Electrical installation, maintenance, and repair tasks requiring secure wire ends
 Applications where conductor protection and improved crimp contact are needed
When it may not be suitable
These ferrule sleeves are intended for stranded copper conductors and standard crimping tools; they are not suitable for solid conductors or for use where a different material or plating is required (for example, tinned sleeves for corrosive environments). They may also be inappropriate if larger or smaller diameter sleeves are specified by the terminal or connector manufacturer.
Key specifications
 Material: copper conductive body with polypropylene insulating collar
 Colour: grey
 Nominal outer diameter: 4.8 mm
 Length: 12 mm
 Pack quantity: 100 pieces
How to use
Strip the conductor to the required length, insert the stranded conductor fully into the ferrule sleeve until the insulation collar seats against the conductor insulation. Use a suitable crimping tool sized for the sleeve and conductor cross-section to apply a firm, even crimp. After crimping, check that the conductor is securely held and that the insulation collar provides proper insulation clearance. Insert the crimped ferrule into the intended terminal or connector and secure according to the connector manufacturer's instructions.
What to consider before purchase
 Confirm compatibility with the conductor cross-section and terminal dimensions
 Ensure your crimping tool is appropriate for 4.8 mm nominal outer diameter ferrules
 Consider environmental conditions; polypropylene collars are not a substitute for corrosion-resistant plating where required
 Verify pack quantity meets project or stocking needs (100 pieces per pack)
Usage recommendations
Use with stranded copper conductors of the matching cross-section and a calibrated crimping tool to ensure reliable, repeatable terminations. For installations exposed to moisture or corrosive atmospheres, consider sleeves with additional protective plating or appropriate environmental protection measures.
