The required mating receptacles are from the AMP
MTA100 series of IDC (insulation displacement)
connectors. Parts are available that are compatible
with 22-28 AWG wire. The color of the receptacle
indicates the intended wire gauge. The part number
for the 3-terminal receptacle that is compatible with
24 AWG is AMP 3-643814-3. The part number for
the 2-terminal receptacle that is compatible with
24 AWG is AMP 3-643814-2. These receptacles
are white in color.
For effective and reliable termination a semi-
automatic termination tool is recommended. At
Studio Technologies we get excellent results using
the AMP 58074-1 handle assembly with associated
die 58246-1. (For reference you’ll find these items
stocked by Digi-Key: www.digikey.com.) This tool
assembly will support 22-28 AWG and stranded
wire should be used.
