B. Contact and Wire
The contacts accept stranded copper or tin--coated wire sizes 26 through 18 AWG with an insulation
diameter range of 1.02 through 2.11 mm [.040 through .083 in.]. Selection of the contact depends upon the
wiresizeaslistedinFigure3.

3.5. Wire Preparation
A. Wire Stripping
Proper strip length is necessary to properly insert the wire into the contact. Reasonable care must be
taken not to nick, scrape, or cut any part of the wire during the stripping operation. The strip length of the
wire is shown in Figure 4. There must be no loose wire strands and the conductors must not be cut. The
wire insulation must be round and there must be no flaws, dents, or other damage.
B. Wire Seal
The wire seal must be installed onto the wire before or after stripping the wire. It is recommended to install
the wire seal after stripping the wire; however, if installing before stripping the wire, the wire seal must be
protected from being damaged during the stripping operation. The wire seal must be installed onto the
wire, flanged end (end opposite the throat) first. The wire seal must be located on the wire so that the wire
insulation is flush with or extends beyond the wire seal to the dimension stated in Figure 4.
After installation, there must be no flaws or other damage to the wire seal, and the shape of the wire seal
must be maintained.

3.6. Crimp Requirements
A single wire per contact is recommended for use with these connectors. Dual wire crimps are not compatible with the
wire seals.
The contact must be crimped to the wire according to instructions packaged with applicable tooling.
