Three benefits of our cable end sleeves
What do our customers say?
Which ferrules suit your activities?
- Insulated ferrules: provide safe termination of flexible wires, especially when used in terminal blocks or switchgear. The plastic collar facilitates insertion and prevents contact between wires.
- Uninsulated ferrules: compact and ideal for limited space in distribution boxes. Suitable for applications where visual or mechanical protection is less critical.
- Twin arrels: designed to merge two wires into one ferrule. Essential in control panels where parallel wiring or group connections are required.
- Ferrules according to DIN 46228: available in color coding according to standard or based on cross-section. This allows you to work faster, prevent errors, and maintain overview during installation.
- Available per type, set, or assortment: whether you are building a series of control cabinets or performing maintenance, Nedelko delivers the ferrules you need – loose, in set, or as a complete sorting box.
Does your ferrule meet the requirements or are you taking a risk?
A ferrule may seem like a small component, but in practice, it determines the reliability of your electrical connection. Poor fit, incorrect dimensions, or inferior material choice can result in loose wires, transition resistance, heat generation, or even rejection during inspection.
At Nedelko, we only supply ferrules that comply with the applicable standards such as DIN 46228, with optimal wall thickness, uniform ferrule geometry, and consistent inner dimensions. Whether you are working with single flexible wires or with two wires in a twin ferrule: you are assured of a strong, durable connection.
Common risks with substandard materials:
- Inadequate contact surface and poor crimp results
- Incompatibility with crimping tools or ferrule equipment
- Incorrect color coding or deviation from the DIN standard
- Susceptibility to corrosion or metal deformation under prolonged load
That's why you choose quality that is demonstrably compliant at Nedelko:
- Insulated ferrules: with a sturdy collar for perfect positioning in the crimping tool
- Twin ferrules: for double connection with optimal conductivity
- Material selection: electrolytically tinned copper, corrosion-resistant and with stable wall thickness
- Color coding according to DIN: for quick identification of the correct size during assembly
- Suitable for automatic and manual processing: compatible with Elematic tools and other pro-tools
Our specialists assist you in choosing the right ferrule for your wire thickness, installation method, and environment.
This way, you prevent rejection and failure costs.
