Crimp ferrule Erko MS_6,3-1/100 — unplated wire ferrules 100 pcs, 6.3 mm

Erko MS_6,3-1/100 is a pack of 100 unplated crimp ferrules designed for terminating stranded conductors with a 6.3 mm nominal blade/terminal fit. These ferrules are intended to improve mechanical stability and electrical contact in screw or terminal-block connections, commonly used in electrical installations, control cabinets and maintenance tasks. The unplated metal construction offers a basic conductive sleeve for consistent conductor insertion and crimping.

Advantages

The ferrules deliver uniform conductor end preparation that reduces wire strand fraying and improves insertion into terminal points. A consistent internal diameter and straight sleeve geometry enable reliable crimping with standard ferrule crimp tools. Supplied in a pack of 100, they facilitate repeated use across multiple terminations and projects without the need to handle individual loose sleeves repeatedly.

Suitable for

• Terminating stranded copper conductors for screw terminals and terminal blocks
• Control panel wiring and industrial electrical cabinets
• Maintenance, repair and field wiring tasks requiring repeatable conductor ends
• Applications where a 6.3 mm nominal terminal fit is specified

When it may not be suitable

These ferrules are unplated and therefore do not provide additional corrosion protection or plated-contact benefits. They are not intended for use where plated or insulated ferrules are required by specification, nor where connection environments demand enhanced anti-corrosion properties or environmental sealing.

Key specifications

• Package quantity: 100 pieces
• Ferrule type: unplated, straight sleeve
• Nominal terminal fit: 6.3 mm
• Intended conductor type: stranded copper conductors
• Application: crimp termination for screw/terminal-block connections

How to use

Strip the conductor to the recommended length for the ferrule sleeve, insert the stripped strands fully into the ferrule until the insulation meets the sleeve end, then crimp the ferrule using a suitable insulated ferrule crimping tool sized for the sleeve diameter. After crimping, visually inspect the connection for tightness and secure the ferrule into the terminal screw or block, ensuring reliable electrical and mechanical contact.

What to consider before purchase

• Confirm the ferrule sleeve diameter matches the terminal or connector specifications (6.3 mm nominal fit).
• Verify compatibility with the conductor cross-section and crimping tool being used.
• Consider whether plated or insulated ferrules are required for corrosion protection or mechanical strain relief.

Usage recommendations

For consistent results, use a calibrated crimping tool appropriate for unplated ferrules and follow standard wiring practice: correct strip length, full insertion of strands, and post-crimp inspection. Store the pack in a dry environment to avoid contamination before use.
