All numerical values are in metric units [with U.S. customary units in brackets]. Dimensions are in millimeters [and inches].

Unless otherwise specified, dimensions have a tolerance of ±0.13 [±.005] and angles have a tolerance of ±2°. Figures and

illustrations are for identification only and are not drawn to scale.

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.
