Series 79 Micro-Crimp signal, power and coaxial contacts are crimped to wire using mil spec crimpers. The Micro-Crimp connector features crimp, rear-release size #23 contacts on .075 inch (1.9 mm) spacing, as well as size #12 and #16 power, coaxial, fi ber optic contacts in a range of hybrid layouts. Available in 31 insert arrangements, the Micro-Crimp provides a wide selection of arrangements for data and power transmission. Military Specifi cation MILDTL-22520 provides the aerospace/defense industry with a common set of rugged, reliable hand crimp tools. This specifi cation controls the voltage drop and tensile strength of crimp terminations. The Series 79 Micro-Crimp family of products is well-supported with a complete range of contacts, tools and assembly instructions for turnkey assembly and use.

 |
- Adapter for Crimping #20 AWG Wire to Size #23 Series 79 Contacts
Size #22 AWG wire is the largest wire size that fi ts standard size 23 contacts. Use this adapter to attach larger #20 gage wire. First, crimp wire to adapter, then crimp the adapter into the size #23 contact. Adapters are made of tellurium copper alloy #1452, and are gold plated. Crimp with M22520/1-01 tool and 809-138 (Daniels TH653) positioner. These adapters cannot be removed from connectors.
- Size #16 Power Contacts, Crimp Termination
Standard size #16 contacts accept #16 to #20 AWG wire. At rated test current of 13 amps, the maximum voltage drop is 74 millivolts. Contacts are gold-plated copper alloy. Socket contacts feature stainless steel hoods to protect against probe damage. Approved to SAE-AMS-39029. Contacts are bulk packaged. Terminate with M22520/1-01 crimper and M22520/1-04 positioner.
- Size #12 Power Contacts, Crimp Termination
Standard size #12 contacts accept #12 to #14 AWG wire. At rated test current of 23 amps, the maximum voltage drop is 63 millivolts. Contacts are gold-plated copper alloy. Socket contacts feature stainless steel hoods to protect against probe damage. Approved to SAE AS39029. Contacts are bulk packaged. Terminate with M22520/1-01 crimper and M22520/1-04 positioner.
