Tools for Connecting Wires to the Mating Receptacles, continued
For applications where a larger number of Model 5100-Series modules are going to be 
installed it’s worth considering a semi-automatic termination tool. The recommended tool 
consists of a handle assembly and crimp die for MTA-100 receptacles. The total price for 
both, approximately US$300 as of this writing, is steep but the performance that this tool 
assembly provides is excellent. We feel that the time savings and reliability of the connec-
tions warrants the price when many terminations are going to be made:
• Handle Tool, Pistol Grip:
 TE Connectivity (AMP) 58074-1
 Digi-Key part number A2031-ND
 Mouser part number 571-580741
• Crimp Head Die Assembly for MTA-100 Receptacles:
 TE Connectivity (AMP) 58246-1
 Digi-Key part number A1998-ND
 Mouser part number 571-58246-1
Headers on the Printed Circuit Board
The actual part numbers of the header connectors that are soldered into the Model 5121’s 
printed circuit board are provided in this section. But do not order these part numbers with 
the intent of interconnecting signals with the Model 5121! We are providing these details 
only so that interested technical personnel can have the full background on the Model 
5121’s interconnect system. The appropriate mating receptacles are detailed in a previous 
section of this Appendix.
• Analog Audio Inputs (one header):
TE Connectivity (AMP) 2-644486-5 (DO NOT ORDER THIS NUMBER!)
• DC Input/Data (one header):
TE Connectivity (AMP) 2-644486-4 (DO NOT ORDER THIS NUMBER!)
