Line/IFB Output Module
Appendix A–Interconnection Details
The required mating receptacles are from the TE Connectivity (formerly AMP) MTA-100
series of IDC (insulation displacement) connectors. This series was selected because of
its low-cost and wide range of offerings. Separate connectors are offered for compatibility
with 22, 24, 26, and 28 AWG (American Wire Gauge) insulated wire. The connector color
indicates its AWG-compatibility. Unfortunately, with flexibility can come some confusion. The
MTA-100 offers a number of different connectors that will work with the Model 5121’s ana-
log audio inputs and DC input/data headers. Before obtaining receptacles it’s important to
determine two things: wire gauge and wiring arrangement.
Analog Audio Inputs (one connector required)
• For 22 AWG wire this receptacle (red in color) is recommended:
TE Connectivity (AMP) 3-643813-5
Digi-Key part number A31109-ND (www.digikey.com)
Mouser part number 571-3-643813-5 (www.mouser.com)
• For 24 AWG wire this receptacle (white in color) is recommended:
TE Connectivity (AMP) 3-643814-5
Digi-Key part number A31020-N
Mouser part number 571-3-643814-5
DC Input/Data (one connector required)
• For 22 AWG wire this receptacle (red in color) is recommended:
TE Connectivity (AMP) 3-644540-4
Digi-Key part number A31122-ND
Mouser part number 571-3-644540-4
Tools for Connecting Wires to the Mating Receptacles
For applications where just a few Model 5100-Series modules are going to be installed a
manual IDC termination tool is recommended. While requiring a steady hand to achieve
reliable wire connections to the mating receptacles, the price, at less than US$40, is fairly
reasonable:
• “T Handle” termination hand tool:
TE Connectivity (AMP) 59803-1
Digi-Key part number A9982-ND
Mouser part number 571-598031
