16、ENTS Part 2-108: Circular connectors Detail specification for glass to metal seal style M12 connectors with screw-locking intended to mate with connectors conforming to IEC 61076-2-101 FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization com
17、prising 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 International Sta
18、ndards, 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 this pre
19、paratory 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 two organ
20、izations. 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 the form
21、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 misinterpretati
22、on 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 or regi
23、onal publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this pub
24、lication. 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 Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect
25、, 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 to the Normative references cited in this publication. Use of the referenced publications is indispensable for the co
26、rrect 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 held responsible for identifying any or all such patent rights. A PAS is a technical specification not fulfilling th
27、e requirements for a standard, but made available to the public. IEC-PAS 61076-2-108 has been prepared by subcommittee 48B: Connectors, of technical committee 48: Electromechanical components and mechanical structures for electronic equipment. The text of this PAS is based on the following document:
28、 This PAS was approved for publication by the P-members of the committee concerned as indicated in the following document Draft PAS Report on voting 48B/1975/PAS 48B/2037/RVD Following publication of this PAS, which is a pre-standard publication, the technical committee or subcommittee concerned may
29、 transform it into an International Standard. DD IEC/PAS 61076-2-108:2009 4 PAS 61076-2-108 IEC:2009(E) This PAS shall remain valid for an initial maximum period of 3 years starting from the publication date. The validity may be extended for a single 3-year period, following which it shall be revise
30、d to become another type of normative document, or shall be withdrawn. This PAS complements IEC 61076-2-101 Ed.2 by adding glass to metal seal styles and the required testing. The following notable additions have been made: the introduction of glass to metal seal fixed connector styles WM, XM, YM an
31、d ZM; the glass to metal styles are intermateable with free connector styles in IEC 61076-2-101 Ed.2; pressure differential test has been added to the test groups; additional contact termination types added: eyelet the termination end is flattened and pierced with a hole to provide both mechanical r
32、etention of the wire as well as solder attachment, rounded terminal post with rounded (domed) end, PCB termination spills suitable for insertion into printed circuits.

36、ustrial process measurement and control. These connectors consist of fixed glass to metal sealed styles with rewireable male contacts. Female connectors have round contacts 0,6 mm, 0,76 mm, 0,8 mm and 1,0 mm. The different codings prevent the mating of these coded male or female connectors to any ot
37、her interfaces and cross-mating between the different codings. NOTE M12 is the dimension of the thread of the screw locking mechanism of these circular connectors. 1.2 Recommended method of termination The contact terminations shall be of the following types: Eyelet, solder PCB, rounded or crimp. 1.
