There’s a new Aerospace Standard AS 39029 Revision C (also known as AS39029). Titled “Contacts, Electrical Connector, General Specification For,” the new 93-page edition makes corrections to bring the document into alignment with the draft originally approved for the previous release. Apparently inappropriate information on PdNi plating requirements were included in Revision B that were not part of the draft approved for that edition.
AS 39029C covers the general requirements for removable crimp, solderless wrap, and solder type electrical contacts for use in connectors and other electric and electronic components (section 6.1). These contacts are specified to be capable of operating within defined temperature ranges (section 3.1).
Four types of contacts and bushings are included in the standard:
- A) Copper Alloy
- B) Ferrous Alloy
- C) Nickel-Chromium (formerly Chromel), Nickel-Aluminum/Silicon (formerly Alumel), Copper-Nickel Alloy (formerly Constantan), Iron and Copper
- D) Copper Alloy
There are quite a number of specification sheets for AS39029 (over a hundred). Each covers a unique type of contact. The series replaced the now obsolete MIL-C-39029 specifications issued by the Department of Defense.
