## Long description

Rittal AS 4051.576 insulated ferrules are designed for terminating 0.5 mm² conductors in electrical installations. Each ferrule features a tin-plated copper conductor and an orange polypropylene (PP) insulated sleeve with a length of 12 mm and an outer diameter of 2.9 mm. Supplied in a pack of 500, these ferrules facilitate consistent, reliable crimped connections for control cabinets, terminal blocks and general wiring tasks.
Advantages
These insulated ferrules provide a compact, standardized end termination that improves contact reliability and prevents strand fraying in crimped connections. The tin-plated copper core ensures good conductivity and corrosion resistance, while the polypropylene sleeve offers electrical insulation and a clear visual identification by color. Supplied in a pack of 500, they support efficient installation workflows and reduce the need for repeated rework.
Suitable for
 Terminating 0.5 mm² stranded conductors in control cabinets and distribution blocks
 Wire-to-terminal connections in terminal strips, relays and connectors
 Manufacturing and field wiring where standardized, consistent crimp terminations are required
When it may not be suitable
These ferrules are specifically sized for 0.5 mm² conductors; they are not suitable for larger or smaller conductor cross-sections. They are intended for crimp termination and are not a substitute for soldered joints or specialized high-current terminations. If a different sleeve material or color coding is required for a particular standard, these orange polypropylene-sleeved ferrules may not meet that requirement.
Key specifications
 Conductor material: tin-plated copper
 Insulation material: polypropylene (PP)
 Conductor cross-section: 0.5 mm²
 Insulation length: 12 mm
 Outer diameter (sleeve): 2.9 mm
 Pack quantity: 500 pieces
 Color of sleeve: orange
 With plastic collar for secure crimping
How to use
Strip the conductor to the appropriate length so the bare strands fully enter the ferrule tube. Insert the stripped conductor into the ferrule until it seats against the collar. Use a suitable insulated-ferrule crimping tool sized for 0.5 mm² ferrules and apply a single, solid crimp to compress the conductor and sleeve together. After crimping, verify mechanical retention and electrical continuity before final assembly into terminals or connectors.
What to consider before purchase
 Confirm conductor cross-section is 0.5 mm² and compatible with the ferrule inner barrel diameter
 Ensure the ferrule insulation length (12 mm) is suitable for the terminal depth or connector being used
 Verify the orange sleeve color and polypropylene material meet any color-coding or environmental requirements
 Check that you have the correct crimping tool for insulated ferrules of this size
Usage recommendations
For repeatable results, use a calibrated crimping tool rated for 0.5 mm² insulated ferrules and perform a pull test on a sample after crimping. Store packs in a dry environment to avoid contamination of sleeves, and keep them organized by color to support consistent wiring and maintenance.
