32、scription The M12-FO connector family is a duplex plug connector set of plug/adaptor configuration which is characterized by a 2,5 mm nominal ferrule diameter and can be used for fibres as described in Table 1. This circular connector includes a housing with a M12-thread screw locking mechanism and
33、a protection according to IEC 60529, IP 65 and IP 67. Electrical M12-connectors are typically used for industrial process, measurement and control. They are described and dimensioned in IEC 61076-2-101 and additional information for the optical connector is given in this standard. BS EN 61754-27:201
34、3 6 61754-27 IEC:2013 The coupling mechanism is spring loaded relative to the ferrules in the direction of the optical axes. The ferrules stand back from the front face in the unmated condition due to a shroud to shelter them from mechanical impact during handling and the mating process. The plug an
35、d adaptor are equipped with four keys to define the mating orientation of the duplex connector. The optical alignment mechanism of the adaptor is from a resilient sleeve style. The alignment mechanism for the active device interface can be a rigid bore or a resilient sleeve. 4 Interfaces 4.1 General
