Phoenix Logistics, Inc. (PLI) designed, developed, and currently produces program specific MIL-STD-1553 contacts that cover a wide frequency spectrum.

We entered the MIL-STD-1553 databus contact market to meet customer concerns regarding price and availability of unique 1553 contacts that have been worked into the avionics bus of a program and become specified commodities for that program. For many of these data bus contacts there was only one supplier, leaving many programs vulnerable to the vagaries of a single supplier.

Such has been the case with Solder Tacs® provided by TYCO (Raychem Corporation). Phoenix Logistics developed STS Contacts which are the equivalent to Raychem D602-126 and D602-127 contacts. PLI has also designed replacements for discontinued Raychem Solder Tacs®.

Phoenix Logistics utilized the same approach for equivalent 1553 contacts to Radiall's EPX® Triaxial contacts. In this case, development was driven by C-17 Globemaster cost reductions. PLI also offers contacts meeting Bell Helicopter specification 30-280 and 30-281.

Phoenix Logistics has also developed Microwave Contacts utilizing a moldable plastic with a dielectric constant equivalent to Teflon®.

PLI MIL-STD-1553 data bus contacts meet the requirements of Mil-C-39029 and SAE-AS-39029 and for use in Mil-DTL-38999 and Mil-C-83723 connectors.

Phoenix Logistics has long been a primary user of Raychem (Tyco) Solder Tacs®. They are widely specified and have been a reliable system of 1553 contact attachment. Because of the volume of our own use, Phoenix Logistics found it advantageous to develop it's own unique Solder Tack System (STS) of equivalent MIL-STD-1553 contacts.

Through involvement in a number of different airborne programs, PLI discovered that many airborne avionics systems prefer crimp contacts to solder contacts. To meet this demand, Phoenix Logistics developed a unique Crimp Tack System (CTS) contact.

Currently equivalent MIL-STD-1553 Solder & Crimp Tacks available are (equivalent Raychem part numbers are listed for cross reference):
