## Long description

Rittal AS 4050.757 ferrules are insulated wire end sleeves combining a copper conductor with polypropylene (PP) insulation in turquoise. Each ferrule measures 8 mm in length and 2 mm in inner diameter, supplied in a pack of 500. Designed for reliable conductor termination, these ferrules provide consistent crimped connections for electrical wiring in control cabinets, industrial panels and general electrical installations where neat, secure terminations are required.
Advantages
The copper tube ensures low contact resistance and good conductivity while the polypropylene insulation resists mechanical abrasion and provides color-coded identification. Their standardized 8 mm length and 2 mm diameter simplify selection for conductors of compatible cross-section, and the pack of 500 supports batch operations and reduces reordering frequency. The plastic collar aids positioning during crimping and offers strain relief at the wire entry.
Suitable for
 Termination of stranded copper conductors in control cabinets and distribution blocks
 Crimped connections on terminal blocks and screw terminals
 Industrial panel wiring and machine control circuits
 Prepping wire ends for quick, reliable insertion and removal during maintenance
When it may not be suitable
These ferrules are intended for use with stranded copper conductors and are not suitable for solid conductors or aluminum conductors without appropriate conversion or adapters. They are sized for conductors compatible with an inner diameter of 2 mm and an 8 mm sleeve length; wires significantly larger or smaller than the intended cross-section will not form reliable crimps.
Key specifications
 Conductor material: copper tube
 Insulation material: polypropylene (PP), turquoise
 Sleeve length: 8 mm
 Inner diameter: 2 mm
 Package quantity: 500 pieces
 Feature: plastic collar for positioning and strain relief
How to use
Strip the stranded copper conductor to the appropriate length so the bare conductor fully enters the copper sleeve. Insert the conductor into the ferrule until the insulation collar abuts the wire insulation. Use a suitable crimping tool matched to the ferrule size to compress the copper sleeve evenly, creating a gas-tight connection. After crimping, verify that the ferrule is secure by applying a gentle tensile test and inspect for any loose strands. Insert the terminated end into the terminal block or screw terminal and tighten according to the terminal manufacturer's torque specification.
What to consider before purchase
 Ensure the ferrule inner diameter and sleeve length match the conductor cross-section and insulation stripping length
 Confirm compatibility with your crimping tool and terminal type
 Consider the required quantity and whether a pack of 500 fits your project needs
 Verify material suitability for the application environment (electrical, mechanical and temperature conditions)
Usage recommendations
Use matched ferrule crimping dies and perform a sample pull test after crimping. Store ferrules in a dry environment to prevent contamination of the copper sleeve and maintain consistent crimp quality.
