4 Description

4.1 General

This document describes an optical connector module to be installed in plug and receptacle housings

Plug and receptacle housings conform to EN 4644-001

There are two sizes of connector housings:

 Housing size 1 with 1 module cavity

 Housing size 2 with 2 module cavities

The connectors use rear removable optical contacts with a ferrule diameter of 1,25 mm

The precise alignment of the optical contacts is accomplished by alignment sleeves held in a removable sleeve holder

The receptacles and plugs contain either male or female module The female module is characterised by its ability to receive the removable sleeve holder

The modules can be installed and removed from the shell by means of a tool as specified in EN 4644-003

The modules are keyed to prevent mismatching (“A” module for connector housing cavity “A” and “B” module

for connector housing cavity “B”) as specified in EN 4644-001

The connectors are keyed as specified in EN 4644-001

Connector type designation as specified in EN 4644-001

4.2 Receptacle

Receptacle description as specified EN 4644-001

4.3 Plug

Plug description as specified EN 4644-001

4.4 Materials and surface treatment

4.4.1 General

When dissimilar metals are in close contact, adequate protection against corrosion shall be used for the electromotive force of the cell not to exceed 0,25 V (see EN 3197)

4.4.2 Housings

The connector housing description as specified in EN 4644-001

4.4.3 Optical contacts and alignment sleeves

The contacts shall be of suitable materials as specified in the product standard

The optical alignment sleeves shall be of suitable materials as specified in the product standard

The optical contacts are spring-loaded The spring force is defined in the product standard

4.4.4 Metallic or non-metallic materials

The materials used for modules, seals and grommets shall have a hardness and mechanical characteristics

consistent with the required use

5 Design

5.1 Housing

The connector housing design as specified in EN 4644-001

5.2 Modules

The modules carrying the optical contacts shall be in hard material and have a cross section and radii such

that no cracks, flaking or breaks can occur in normal operation

The contact module is mechanically held in the connector housing by retention clips, and removable with the

use of an extraction tool

The mechanical contacts retention system shall be integrated in the hard module

The front face of the module shall be such that sealing is ensured when the connectors are coupled The

interfacial seal of the module of the male contacts shall be permanently fastened on the hard module

Sealing of the rear face of the module is provided by a grommet adapted to the external diameter of the cable

The design shall permit individual installation of the contacts without removal of the module

Installation and removal of the contacts shall be from the rear For ease of operation, tools as per

MIL-I-81969/14-03 standard (P/N for size 16) may be used

Contact position identification shall be permanent and contrasted on the rear face of the insert or grommet
