FDD/FDVD Pre-insulating Female Terminals (Single and Double Crimp)
YOCL ELECTRIC FDD/FDVD female terminals pair a brass receptacle with a PVC insulating sleeve. FDD is the single-crimp version; FDVD adds a copper tube sleeve for double crimp.
- 22 FDD and 22 matching FDVD models across three conductor groups.
- Conductor sections: 0.5–1.5, 1.5–2.5 and 4–6 mm².
- NEMA tab sizes and material thickness vary by model.
- Compare B, D, d, L1, L2 and E in the dimensional table.
Overview
YOCL ELECTRIC FDD/FDVD Pre-insulating Female Terminals are brass female receptacles with PVC insulation. FDD models use a single crimp, while matching FDVD models use a double crimp with a copper tube sleeve. The source lists 22 paired rows across three conductor groups.
Features
- Single and double crimp choices: matching FDD and FDVD model codes appear together in the table.
- Brass receptacle and PVC sleeve: materials stated for the three conductor groups.
- Tab selection: NEMA tab size and contact material thickness vary by model.
- Size-based fit: barrel diameters, body lengths and terminal widths are given for each row.
