3.7. Interface Seal

The interface seal must be installed onto the plug housing. The installed interface seal must fit inside the

channel at the base of the silos of the plug housing. The interface seal must remain flat against the back of the

channel and shall not be twisted. There shall be no tears, rips, or other damage to the interface seal. Refer to

Figure 8.

A method to prevent damage to the interface seal is to use the mating cap housing (without contacts) or pin header

(not installed onto pc board) to slide the interface seal along the silos and against the back of the channel.

3.8. Installing Contacts into Housing

The contacts must be installed into the plug housing and cap housing. Each contact must be inserted into a

contact cavity at the wire end of the housing until it bottoms (there should be an audible “click”). For optimum

sealing performance, the wire seal on the contact must have at least two of the three flanges fully inserted into

the contact cavity. Each contact must be locked into place. Refer to Figure 8.

Because of the wire seal, these contacts require more insertion force than unsealed contacts (without a wire seal).

3.9. Cavity Plug Seal

The cavity plug seal must be installed into any unused contact cavities of the plug housing and cap housing.

The cavity plug seal must be inserted (short tab end first) into the contact cavity at the wire end of the housing.

For optimum sealing performance, the cavity plug seal must have at least two of the three flanges fully inserted

into the contact cavity. See Figure 8.

A cavity plug seal must also be installed in any mating contact cavity containing a keying plug. See Figure 8.

The cavity plug seals can be installed manually or by using Insertion Tool 91002--1. Instruction for using the tool is

provided on Instruction Sheet 408--7347.

3.10. Keying Plug

The keying plug must be installed into an empty contact cavity in the plug housing or cap housing. The keying

plug must be inserted (tapered end first) into the contact cavity at the mating face of the housing until it

bottoms (there should be an audible “click”).
