Aperçu
FDFN / FDFNYD Nylon Female Terminals are insulated brass receptacles for compatible flat tabs. FDFN uses a single crimp; FDFNYD is the corresponding double-crimp version with a copper tube sleeve. Both styles are shown together for direct model and dimension comparison.
Caractéristiques
- Paired crimp styles: each FDFN model is listed with its FDFNYD counterpart.
- Several plug sizes: the catalog lists 2.8, 4.75 and 6.35 mm tab widths with the thickness specified by model.
- Insulated brass receptacle: brass terminal and nylon sleeve as identified in the supplied catalog.
- Color-coded groups: red, blue and yellow separate the listed model sizes.
Spécifications techniques
The temperature and voltage are catalog values; the source does not provide a certification or operating conditions.
Dimension
All dimensions are in millimeters. D1 and D2 identify the single-crimp and double-crimp sleeve diameters in the supplied drawings. Plug specification gives tab thickness × width.
