## Summary description

Rittal AS 4051.638 crimp ferrules (aderendhülsen) are copper conductors with polypropylene (PP) insulation, color: white. Each ferrule measures 10 mm in length and 2.6 mm in diameter. Supplied as a pack of 1000 pieces, they provide reliable wire termination for electrical connections, ensuring secure crimps and improved contact for control cabinets, wiring harnesses and industrial installations.

## Long description

Rittal AS 4051.638 copper crimp ferrules with polypropylene insulation are designed to provide reliable wire termination for control cabinets, wiring harnesses and industrial electrical installations. Each insulated ferrule has a 10 mm overall length and a 2.6 mm inner diameter, with a white polypropylene collar that supports secure crimping and consistent contact between conductor and termination point. Supplied in a pack of 1000 pieces, these ferrules follow standardized design and colour coding used for quick identification during assembly and maintenance.
Advantages
These insulated ferrules combine a copper conductor barrel and a polypropylene insulated collar to improve mechanical stability and electrical contact. The polypropylene insulation protects against stray strands and makes insertion into terminal blocks easier, while the copper barrel ensures low contact resistance and durable crimps. The consistent dimensions and factory-finished ends facilitate repeatable crimps with hand or machine crimping tools, reducing the risk of loose or frayed conductors.
Suitable for
Stranded copper conductors that match the ferrule inner diameter
Control cabinets, terminal blocks and distribution panels
Wiring harnesses and industrial machinery terminations
Assembly lines where bulk-supplied ferrules are required
When it may not be suitable
These ferrules are intended for stranded copper conductors and may not be suitable for solid wires, aluminium conductors, or wire sizes that do not match the 2.6 mm inner diameter. They are insulated with polypropylene which provides mechanical support and basic electrical insulation but does not replace full heat-shrink or high-temperature-rated insulation where such properties are required.
Key specifications
Material of conductor: copper
Insulation material: polypropylene (PP)
Insulation colour: white
Overall length: 10 mm
Inner diameter: 2.6 mm
Pack quantity: 1000 pieces
How to use
Select an insulated ferrule matching the conductor cross-section and strip the cable to the recommended length. Insert the stripped, stranded conductor fully into the copper barrel so that strands are contained within the ferrule. Use an appropriate crimping tool—handheld or machine crimper—sized for the ferrule to compress the barrel uniformly. After crimping, verify the mechanical strength by a light pull test and check for good electrical contact before final installation into terminal blocks or connectors.
What to consider before purchase
Ensure the ferrule inner diameter and length are compatible with your conductor size and terminal requirements
Confirm the ferrules are suitable for stranded copper conductors used in your application
Consider whether polypropylene insulation meets your temperature and environmental requirements
Usage recommendations
For reliable terminations, use a calibrated crimping tool appropriate for insulated ferrules and perform sample pull tests during assembly. Store the pack in a dry environment and match ferrule size to conductor cross-section to maintain low contact resistance and prevent strand splay.
