Durability

(Meets SAE-AS39029, paragraph 3.5.9) No electrical or mechanical defects after 500 cycles of engagement & disengagement

Contact Retention

(Meets MIL-DTL-38999, paragraph 3.23) The axial displacement of the contact shall not exceed .012 inch (0.30 mm). No dam-

age to contacts or inserts shall result.

Pin Engagement End

(Meets SAE-AS39029 paragraph 3.4.1) Unless otherwise specified, the mating end of all contacts (except size 22 and smaller)

shall be formed with an approximate spherical radius.

Permeability

(Meets SAE-AS39029, paragraph 3.5.1) When tested as specified in paragraph 4.7.2, the relative magnetic permeability of the

contact shall be no greater than 2.0.

Vibration

(Meets SAE-AS39029, paragraph 3.5.10) When contacts are tested as specified in paragraph 4.7.11, there shall be no electri-

cal discontinuity of 1 microsecond or greater. There shall be no defects detrimental to the mechanical or electrical perfor-

mance.

Salt Spray (corrosion)

(Meets SAE-AS39029, paragraph 3.5.12) When tested as specified in 4.7.13. mated contacts shall withstand 48 hours of salt

spray conditioning without defects detrimental to the mechanical or electrical performance.

Temperature life

(Meets SAE-AS39029, paragraph 3.5.13) When tested as specified in paragraph 4. 7. 14, mated contacts shall withstand tem-

perature conditioning for 1,000 hours without defects detrimental to mechanical or electrical performance. There shall be no

diffusion/migration of the base metal through the contact outer plating Class A - Maximum operating temperature +125°C.

per paragraph 1.2.2

Dielectric withstanding voltage (Meets SAE-AS39029, paragraph 3.5.19) When tested as specified in paragraph 4.7.20, crimped contacts shall show no evi-

dence of breakdown or flashover.

Workmanship

(Meets SAE-AS39029, paragraph 3.7) Contacts shall be processed in such a manner as to be uniform in quality and shall be

free from foreign material & burrs or sharp corners that might damage the connector or affect mating of the contacts. Burrs

& sharp edges shall be removed 0.005 inch max. (0.13mm)
