Non-Insulated Ferrules

A non-insulated ferrule is a tin-plated copper tube without a plastic collar, crimped onto the stripped end of a multi-strand conductor. It is used to connect the strands of a flexible conductor together in narrow terminal block entries, where a collar would take up space, and in closely spaced terminal rows. In this category, Konsan, Isıso and Gwest ferrules are available in cross-sections such as 0.5 mm², 0.75 mm², 1.5 mm², 2.5 mm², 6 mm², 16 mm² and 50 mm², and tube lengths such as 10 mm, 12 mm and 15 mm. Choose according to the conductor cross-section, the tube length that matches the clamping depth of the terminal block, the inner and outer diameter of the tube and the die of your crimping pliers. Because it carries no color code, the cross-section is tracked from the product name and packaging; the DIN 46228 standard is stated in the Konsan and Gwest product data. A non-insulated ferrule should not be confused with a cable lug with a hole that sits under a bolt; a ferrule is just a straight tube that goes into a terminal block.

How to choose Non-Insulated Ferrules

A non-insulated ferrule is a tin-plated copper tube without a plastic collar, crimped onto the stripped end of a multi-strand conductor. It is used to connect the strands of a flexible conductor together in narrow terminal block entries, where a collar would take up space, and in closely spaced terminal rows.

  • Clarify whether the task is connection, cable routing, enclosure distribution or termination.
  • Match dimensions, thread standard, conductor cross-section and IP rating with the cable and panel.
  • Choose housing material and pack quantity according to the mounting environment.
