1. INTRODUCTION
This specification covers the requirements for application of the waterproof signal double lock connector
system and twist and lock connector system with a 2.5 mm centerline. The waterproof signal double lock
connector system is available in a 2 through 6 position, single row free hanging panel mount configuration for a
22 to 26 AWG wire range.
The twist and lock connector system is available in a 4 or 6 position, dual row and 12 position, triple row free
hanging panel mount configuration for a 22 to 26 AWG wire range.
The optional seals on the waterproof signal double lock and the twist and lock connector system are rated to
IP67. If seals are required, the mating interface seal must be used in conjunction with the gang seal. Terminal
position assurance (TPA) accessories are available for all wire sizes and may be used on connectors with or
without optional seals.
Basic terms and features of this product are provided in Figure 1.

2.5. Specifications
Product Specification 108-143069 provides product performance and test results.
3. REQUIREMENTS
3.1. Safety
Do not stack product shipping containers so high that the containers buckle or deform.
2 of 9
Rev A
114-143067
3.2. Storage
A. Ultraviolet Light
Prolonged exposure to ultraviolet light may deteriorate the chemical composition used in the product
material.
B. Shelf Life
The product should remain in the shipping containers until ready for use to prevent deformation to
components. The product should be used on a first in, first out basis to avoid storage contamination that
could adversely affect performance.
C. Reels
When using reeled contacts, store coil wound reels horizontally. When storing partial reeled contacts, the
end of the strip should be secured to the flange using a wire tie or similar method.
D. Chemical Exposure
Do not store product near any chemical listed below as they may cause stress corrosion cracking in the
material.
Alkalies
Amines
Ammonia
Citrates
Nitrites
Phosphates Citrates
Sulfur Nitrites
Sulfur Compounds
Tartrates
Carbonates
3.3. Wire Selection and Preparation
The contacts accept 1 stranded copper wire sizes 26 AWG to 22 AWG with an insulation diameter range of
1.30 to 1.60 mm.
Each wire must be stripped to the dimension given in Figure 2.
CAUTION
Care must be taken not to nick, scrape, or cut any part of the wire during the stripping operation.
Note: Not to Scale
3.0±0.3
Strip Length
Figure 2
3.4. Contact Crimp
A. Cutoff Tab
The cutoff tab is the remaining portion of the carrier strip after the contact is cut from the strip. The cutoff
tab must not exceed the dimensions given in Figure 3.
B. Wire Barrel Crimp
The crimp applied to the wire barrel portion of the contact is the most compressed area and is most critical
in ensuring optimum electrical and mechanical performance of the crimped contact. The crimp must be
centered on the closed wire barrel. The crimp must result in an “F” crimp where the wire barrel forms a
closed seam with no evidence of loose wire strands or wire strands visible in the seam. The crimp height
and width must be within the dimensions given in Figure 3.
C. Insulation Barrel Crimp
The crimp applied to the insulation barrel of the contact must result in an “O” crimp where the tips of the
insulation barrel wrap firmly around the wire insulation without cutting into the wire insulation. The crimp
width must be within the dimensions provided in Figure 3.
3 of 9
Rev A
114-143067
D. Wire Barrel Flash
Wire barrel flash is the formation that may appear on both sides of the wire barrel as the result of the
crimping process. It must not exceed the dimension provided in Figure 3.
E. Twist and Roll
There should be no twist or roll of the wire barrel or mating portion of the crimped contact that would
cause overstress or impair usage. See Figure 3 for allowable limits.
F. Wire End Extrusion
The wire conductor ends must extend beyond the end of the wire barrel within the dimensions given in
Figure 3.
G. Bellmouths
The rear bellmouth shall be evident and conform to the dimensions given in Figure 3.
H. Wire Location
All conductors must be held firmly inside the wire barrel. No strands can be folded back over the wire
insulation. The wire insulation must be inside the insulation barrel, but must not enter the wire barrel. The
wire conductors and insulation must be visible within the area between the wire barrel and insulation
barrel as shown in Figure 3.

3.5. Optional TPA Devices
An optional TPA device is available for the plug housing and cap housing. The following requirements apply for
installation:
NOTE
All contacts must be inserted before the devices can be installed into the housing.
— The TPA device must be installed onto the contact end of the housing so that the latches are secure to
the housing TPA locking tabs. There should be an audible click. If the latches do not reach the locking tabs,
this indicates that one or more contacts has not been fully inserted.
The following requirements apply for removal:
— The TPA device must be removed by lifting each latch so that it clears the housing TPA locking tab,
and pulling the TPA device straight from the housing.

3.6. Panel Mounting
Recommended panel cutout dimensions are provided on the customer drawing for the specific cap housing.
The cap housing must be inserted through the panel in the same direction that the cutout was punched until the
panel stops sit against the panel so that the flexible panel latches engage the panel. No hardware is required.
See Figure 5.
To remove the cap housing from the panel, both latches must be simultaneously depressed, then the cap
housing must be gently pulled straight out of the panel. If there is no damage to the cap housing, the cap
housing can be re-mounted.

3.7. Mating and Unmating
The mating face of the cap housing must align with the mating face of the plug housing, then the housing must
be pushed together until the mating latch is secured to the latch retainer. There should be an audible click.
Refer to Figure 8.
To unmate the housings, the plug housing must be depressed until it is released from the latch retainer, then
the housings can be pulled straight apart.
CAUTION
These housings are not intended to be used as an electrical interruption device. To avoid degradation to the contacts, there
must be no current flow when unmating.
3.8. Strain Relief and Wire Dress
Wires can be bundled together and supported using cable ties or electrical tap. The wires must remain
perpendicular to the housing and avoid an excessively sharp bend radius. The wire bundle must be at least 76
mm [3.0 inch] from the back of the housing before bending in any direction. Do not bend unsupported wires as
this may cause strain on the contacts.

repairable.
