• Extraction tool for J300 series: EJ-JFAJ3
• Refer to page 576, 577 for details of YRK series hand crimping tool
that uses a strip contact.
Recognition mark
• Plating of the contact
Each contact has a marking on its side so that the type or
thickness of the plating is recognized.
ex. 2 ... gold-plated 0.38μm thickness
3 ... gold-plated 0.76μm thickness
5 ... tin-plated

• Common marking on the contact and its application tools
In order to avoid incorrect combination of the hand crimp tools or
extraction tools and the contacts, the series name (for example J-3) and
wire range mark (S, M, L, 2L) are shown on both the tools and the
contacts.
For example J-3 S..... AWG #28 ∼ #24
M.... AWG #24 ∼#20
L..... AWG #20 ∼ #16
