24、754-27 IEC:2013 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS FIBRE OPTIC CONNECTOR INTERFACES Part 27: Type M12-FO connector family FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardizat
25、ion comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes Internatio
26、nal Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in t
27、his preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the t
28、wo organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have t
29、he form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinte
30、rpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national
31、 or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carr
32、ied out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Com
33、mittees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn
34、to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be
35、 held responsible for identifying any or all such patent rights. International Standard IEC 61754-27 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. The text of this standard is based on the following doc
36、uments: FDIS Report on voting 86B/3597/FDIS 86B/3626/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 4 61754-27 IEC:2013 A list
37、 of all parts of the IEC 61754 series, published under the general title, Fibre optic interconnecting and passive components Fibre optic connector interfaces, can be found on the IEC website. Future standards in this series will carry the new general title as cited above. Titles of existing standard
38、s in this series will be updated at the time of the next edition. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date,
39、the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 61754-27 IEC:2013 5 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS FIBRE OPTIC CONNECTOR INTERFACES Part 27: Type M12-FO connector family 1 Scope This part of IEC 61754 defines the standard interfa
40、ce dimensions for the type M12-FO family of connectors. This connector is of duplex plug/adaptor/plug configuration and designed for industrial environment as described in ISO/IEC TR 29106, severity class M 3and I 3 . Multiple designs for machines and equipment require solutions with different fibre
41、 types. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including a
42、ny amendments) applies.

45、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 a protection according to IEC 60529, IP 65 and IP 67. Electrical M12-con
46、nectors 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. 6 61754-27 IEC:2013 The coupling mechanism is spring loaded relative to the ferrules in th
47、e 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 and adaptor are equipped with four keys to define the mating orientation of the duplex connect
48、or. 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 This standard contains the interfaces for the type M12-FO connector family as described in
49、Table 1. The interfaces are intermatable according to Table 2.
