C. Shelf Life
The contacts should remain in the shipping containers until ready for use to prevent deformation to the
contact. The contacts should be used on a first in, first out basis to avoid storage contamination that could
adversely affect signal transmissions.
D. Chemical Exposure
Do not store contacts near any chemicals listed below as they may cause stress corrosion cracking in the
contacts.
Alkalies Ammonia Citrates Phosphates Citrates Sulfur Compounds
Amines Carbonates Nitrites Sulfur Nitrites Tartrates
NOTE
Where the above environmental conditions exist, phosphor-bronze contacts are recommended instead of brass.
3.3. Wire Selection and Preparation
The contacts accept stranded wire size range of 26 through 8 AWG. The acceptable insulation diameter of each
contact is given in the applicator sheet.
Proper strip length is necessary to properly insert the wire into the contact. The strip length of the wire is given in
the applicator sheet. For a list of applicators, see Figure 8.
CAUTION
The wire conductor must not be nicked, scraped, or cut during the stripping operation.
3.4. Crimp Requirements
CAUTION
Wire insulation shall NOT be cut or broken during the crimping operation. Reasonable care should be taken by tooling
operators to provide undamaged wire terminations.
A. Wire Barrel Crimp
The crimp applied to the wire barrel of the contact is the most compressed area and is most critical in
ensuring optimum electrical and mechanical performance of the contact. The crimp height and width must
be within the dimensions provided in the applicator sheet.
B. Insulation Barrel Crimp
The crimp applied to the insulation barrel of the contact must result in either an “F” crimp where the
insulation barrel forms a closed seam with no evidence of wire insulation in the seam or an overlap crimp
where the insulation barrel wraps firmly around the wire insulation without cutting into the wire insulation.
C. Crimp Length
Effective crimp length is defined as that portion of the wire barrel, excluding the bellmouths, fully formed by
the crimping tool. Refer to Figure 2 and the applicator sheet.
D. Bellmouths
Front and rear bellmouths shall be evident and conform to the dimensions given in Figure 2.
E. Cutoff Tab and Burr
The cutoff tab shall be cut to and the cutoff burr shall not exceed the dimensions given in Figure 2.
F. Wire Barrel Flash
The wire barrel flash shall not exceed the dimension given in Figure 2.
G. Wire Location
The wire conductors and insulation must be visible in the transition area (the area between the wire barrel
and insulation barrel). The conductors may extend beyond the wire barrel to the maximum dimension given
in Figure 2.
