The connectors use rear removable optical contacts with a ferrule diameter of 2,5 mm in accordance with

26、 EN 4531-101. The precise alignment of the optical contacts is accomplished by a central alignment pin/socket and alignment sleeves. The receptacles and plugs contain either male or female module. The male module is characterised by alignment pin. The inserts can be installed and removed from the sh

27、ell by mean of a tool as specified EN 4165-022. Keying system conform to EN 4165-001. Connector type designation as specified in EN 4165-001. Not compatible with back shells and cable clamp defined in EN 4165-002. 4.2 Receptacle Receptacle description as specified in EN 4165-001. 4.3 Plug Plug descr

28、iption as specified in EN 4165-001. 4.4 Module Mechanical interface and polarization between housings and modules conform to EN 4165-001. The module assembly shall be single-bloc type design complete with a keyed contact retention system and appropriate seals. The male and female modules use hermaph

29、roditic contacts as specified in EN 4531-101. 4.5 Materials and surface treatment 4.5.1 General See EN 4165-001. 4.5.2 Housings The connector housing description is specified in EN 4165-001.

30、of suitable materials as specified in the product standard EN 4531. The optical alignment sleeves shall be of suitable materials as specified in the product standard EN 4701-002. The optical contacts are spring-loaded. The spring force is defined in the product standard EN 4531. 4.5.4 Metallic or no

31、n-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 is specified in EN 4165-001. 5.2 Modules The modules carrying the optical contacts shall be

32、 in hard material and have a cross section and radii such that no cracks, flaking or breaks can occur in normal operation. The 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

33、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 shall be permanently fastened on the male module. Sealing of the rear face of the module is provided by the contact boot. The design shall permit in

34、dividual installation of the contacts without removal of the module. Insertion and removal of the contacts shall be from the rear. For ease of operation, tools as per M81969/14-04 standard (P/N for size 12) may be used. Contact identification shall be permanent and contrasted on the rear face of the
