KK Trifurcon Crimp
KK Trifurcon Crimp
"KK 396 Crimp Terminal 8818"
They have 2 little prongs between crimp and contact, not sure why. -> They're called an anti-fish hooking feature, as described in the crimping tool manual
| Part nb | Old | AWG | Pack | Finish |
|---|---|---|---|---|
| 08-50-0008 | 8818-(P909) | 18-22 | Reel | Brass Tin (Sn) |
| 08-50-0023 | 8818-(P909)L | 18-22 | Bag | Brass Tin (Sn) |
| 08-52-0131 | 8818-A(P909) | 18-22 | Reel | Phosphor Bronze Tin (Sn) |
| 08-52-0132 | 8818-A(P909)L | 18-22 | Bag | Phosphor Bronze Tin (Sn) |
| 08-58-0135 | 8818-A(550) | 18-22 | Reel | Phosphor Bronze Selective Gold (Au) |
| 08-58-0136 | 8818-A(550)L | 18-22 | Bag | Phosphor Bronze Selective Gold (Au) |
| 08-65-0128 | 8818-A(555) | 18-22 | Reel | Phosphor Bronze Selective Gold (Au) |
| 08-65-0129 | 8818-A(555)L | 18-22 | Bag | Phosphor Bronze Selective Gold (Au) |
Difference between the last two is probably coating thickness
Female Crimp Terminal for 3.96mm Pitch Housing Goes entirely around the contact
Not exhaustive, just a reference for the one I own.
