    19、 Plug and receptacle housings conform to EN EPX-xxx (GT3). 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 c

    20、ontacts 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 inserts can be installed and removed from the shell by mean of

    21、 a tool as specified EN EPX-xxx (GT3). The modules are keyed to prevent mismating (“A” module for connector housing cavity “A” and “B” module for connector housing cavity “B.”) as specified EN EPX-xxx (GT3). The connectors are keyed as specified EN EPX-xxx (GT3). Connector type designation as specif

The optical alignme

    24、nt sleeves shall be of suitable materials as specified in the product standard. The optical contacts are sprung-loaded. The spring force is defined in the product standard.

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 mal

    28、e 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. Fitting and removal of the contact
