4.4.3 Optical contacts and alignment sleeves The material of the optical contacts and alignment sleeves shall be of suitable materials as specified in the appropriate product standard. The optical contacts in both plug and receptacle are sprung-loaded. The spring force is defined in the product standard. 4.4.4 Metallic or non-metallic materials The materials used for insert seals, grommets and alignment pins shall have a hardness and mechanical characteristics consistent with the required use. 5 Design 5.1 Housings The connector housings shall be in one unit. They contain teeth at the rear over the entire periphery and shall accommodate the accessories. The receptacle shall be fitted with an internal seal for sealing the coupled housings. The jam nut receptacle housing shall contain an O-ring seal (panel seal). The lock nut shall be provided with wire locking holes. Threads shall conform to ISO 263, except for the triple start threads, which shall conform to standard MIL-STD-1373. The coupling ring shall be designed so that the optical contacts engage when it is screwed clockwise and disengage when it is unscrewed counter clockwise. The coupling ring shall be designed to provide a hand grip profile. Full locking of the connectors shall occur at approximately 360°. On completion of tightening of the coupling ring, mechanical contact shall exist between the receptacle and plug shells. Masking of a red colour band on the receptacle shall show that the connectors are correctly mated. The front face of the plug shell shall seal when fully mated with the receptacle connector. 5.2 Inserts The 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 operation. The insert for contacts shall be non-removable; it shall be mechanically held in the housing. Sealing shall be provided between the housing and insert. The mechanical contacts retention system shall be integrated in the hard insert. SIST EN 4531-001:2009
