- Seventeen FDFD models are listed in the range.
- Listed wire sections cover 0.5–1.5, 1.5–2.5 and 4.0–6.0 mm².
- Red, blue and yellow insulation identifies the listed size groups.
- Compare mating tab, B, DΦ, dΦ, L and E below.
Overview
The FDFD range provides fully-insulated female disconnect terminals with vinyl insulation, brass contacts and tin plating. Seventeen catalog models are grouped by conductor size and color. Select a compatible male tab together with the terminal’s wire-entry and overall dimensions.
Features
- Fully-insulated body: the vinyl sleeve covers the receptacle and wire-entry areas.
- Tin-plated brass contact: the stated contact material and finish for the FDFD range.
- Female tab receptacle: the socket mates with a compatible male flat-blade terminal.
- Three wire-size groups: select red, blue or yellow from the conductor sections in the model table.
- Multiple mating interfaces: compare the catalog tab dimensions and housing size for each model.

Selection Guide
Start with the conductor section and choose the corresponding color group. Match the female receptacle to the male tab’s thickness and width, then check the wire-entry diameter, insulated housing and overall length. Send a drawing or mating-part reference if you need help confirming the configuration.
Applications
For detachable flat-blade connections in appliance wiring, equipment assemblies, control wiring and maintenance work where the conductor, mating terminal and installation requirements match the selected FDFD model.
Ordering Information
Provide the full FDFD model reference, conductor size, mating tab dimensions and quantity. Include packaging and labeling requirements for OEM or wholesale enquiries.
