Insulated Single-Entry Ferrules

An insulated single-entry ferrule is a cable ferrule made up of a tin-plated copper tube crimped onto the end of a single multi-strand conductor and a colored plastic collar that guides the conductor entry. It is used in panel wiring to connect flexible conductors to terminal block, contactor, relay and PLC terminals without strand fraying. In this category, Gwest, Konsan and Isıso ferrules are available in cross-sections such as 0.25 mm², 0.75 mm², 1.5 mm², 6 mm² and 50 mm², and metal tube lengths such as 8 mm and 12 mm. Choose based on the conductor cross-section, the metal tube length that matches the clamping depth of the terminal block, the color code standard used in the panel (German or French) and the die of your pliers. The collar color indicates the cross-section, but since the same cross-section can be coded with different colors in the two standards, verify the cross-section and standard from the product name when ordering. Nylon insulation, a maximum operating temperature of 105 °C and the DIN 46228 standard are stated in the Gwest and Konsan product data. A single-entry ferrule is not designed to crimp two conductors together; if two conductors will enter the same connection point, use a double-entry ferrule.

How to choose Insulated Single-Entry Ferrules

An insulated single-entry ferrule is a cable ferrule made up of a tin-plated copper tube crimped onto the end of a single multi-strand conductor and a colored plastic collar that guides the conductor entry. It is used in panel wiring to connect flexible conductors to terminal block, contactor, relay and PLC terminals without strand fraying.

  • 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.
