It is suitable for use on aerospace on
10、board applications. It provides easy access for optical contact end face cleaning. The optical contacts are capable of accepting single cable sizes up to a maximum of 2 mm outside diameter. 1 Scope This standard specifies the general characteristics, the conditions for qualification, acceptance and
11、quality assurance, as well as the test programs and groups for rectangular multipin fibre optic connectors. 2 Normative references The following referenced documents are indispensable for the application of this document.

19、housings. Plug and receptacle housings conform to ARINC Specification 600. The precise alignment of the optical contacts is accomplished by alignment sleeves held in a removable sleeve holder. The plug connector contain male insert as specified in EN 4640-003. The receptacles connector contain femal
20、e insert as specified in EN 4640-004. The female insert is composed of an insert and a removable sleeve holder as specified in EN 4640-004. The sleeve holder is delivered with the female insert. It is considered as a part of the female insert (specific design per manufacturer). The sleeve holder can
21、 be supplied separately only for repair purpose. The optical contact is in accordance with EN 4639-101. The connectors are keyed as specified in ARINC Specification 600.

23、3197). 4.4.2 Housings The connector housing description as specified in ARINC Specification 600. prEN 4640-001:20075 4.4.3 Optical contacts and alignment sleeves The contacts shall be of suitable materials as specified in EN 4639-101. The optical alignment sleeves shall be of suitable materials as s
24、pecified in EN 4640-002. The optical contacts are sprung-loaded. The spring force is defined in the product standard (EN 4639-101). 4.4.4 Metallic or non-metallic materials The materials used for inserts, seals and grommets shall have a hardness and mechanical characteristics consistent with the req
25、uired use. 5 Design 5.1 Housing The connector housing design as specified in ARINC Specification 600. 5.2 Connector inserts The connector insert 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 opera
26、tion. The mechanical contacts retention system shall be integrated in the connector insert. Sealing of the rear face of the connector insert can be provided by a grommet adapted to the external diameter of the cable The design shall permit individual installation of the contacts without removal of t
27、he connector insert. Fitting and removal of the contacts shall be from the rear. For ease of operation, tools as per MIL-I-81969/14-03 (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. 6 Definition drawings 6.1
