IEC Foreword
1) IEC (International Electrotechnical Commission) is a worldwide standardization organization composed of national electrotechnical committees (IEC National Committees). The purpose of IEC is to promote international cooperation on standardization issues in the field of electrical and electronic engineering. For this purpose, among other activities, IEC publishes international standards. The formulation of international standards is undertaken by technical committees, and any EC National Committee concerned with the content involved can participate in the formulation of international standards. Any international, governmental and non-governmental organization associated with EC can also participate in the formulation of international standards. EC and the International Organization for Standardization (ISO) maintain close cooperation under the conditions agreed upon by the two organizations. 2) IEC's formal resolutions or agreements on technical issues are formulated by technical committees participated in by national committees with special concerns about these issues, and represent the international consensus on the issues involved as much as possible. 3) These resolutions or agreements are used internationally in the form of recommended standards and are recognized by national committees in this sense. 4) In order to promote international unification, EC hopes that national committees will adopt EC standard texts as their national standards if conditions permit in their own countries. Deviations between EC standards and corresponding national standards shall, as far as possible, be indicated in the national standards. 5) IEC has not established any procedure for the use of the approval mark and shall not be held responsible for claims that a product conforms to the corresponding IEC standard. 6) Attention should be paid to the fact that parts of this International Standard may be the subject of patent rights. EC does not assume any responsibility for any or all of these patent rights identified.

2.4 General requirements for connectors mounted on modules or panels 2.4.1 Limits of radial or axial misalignment of connectors allowed When designing the mounting arrangement of BMA series connectors, it is necessary to control the arrangement of single-pair connectors and their engagement within the following general limit conditions.
2.4.1.1 Radial misalignment
The radial misalignment between the mating connector pairs refers to the concentric deviation between the diameter G of the plug and the diameter T of the socket of the two connectors at the beginning of mating and during mating (see 2.1 Dimensions G and T of the plug and socket). At the beginning of mating and during mating, the radial misalignment of the fixed-mounted plug and socket should be within the range of ?①0.190mm (0.0075in). At the beginning of mating, the radial misalignment of the fixed-mounted plug and the floating-mounted socket should be within the range of ?①1.016mm (0.040in). During mating, the floating connector shall be able to automatically align with the fixed connector within a range of @100.190mm (0.0075n).
2.4.1.2 Axial Misalignment (Axial Play) a) Fixed Plugs and Sockets
To ensure electrical and environmental performance, the reference surface clearance between the two mated connectors shall not exceed 0.38mm (0.015in). When the reference surface clearance between the two mated connectors reaches 0.76mm (0.030in), the electrical performance will be reduced and the environmental performance will fail. b) Fixed Plugs and Floating Sockets The floating mounting allows a total axial displacement of 1.52mm (0.060in). The mounting configuration shall ensure a minimum axial displacement of 0.26mm (0.010in) [0.76mm (0.030in) better to ensure that the total length of engagement is maintained in the working state. 2.4.2 Specific connector installation details
In addition to the details of the panel opening and the maximum panel thickness, the detail specification shall also specify the minimum centerline distance between two adjacent connector pairs, including the X axis and Y axis direction (if not at the same time). 3 Quality Assessment Procedure
3.1 General
The following clauses specify the recommended ratings, performance and test conditions that should be considered when writing a detail specification. It also specifies a list of tests applicable to the minimum level of sampling for consistency inspection, as well as the format of blank detail specifications and guidance for the preparation of detail specifications. 3.2 Ratings and characteristics (see Chapter 6 of GB/T 11313-1996) The following specified values ​​are recommended for BMA series connectors and are for reference by the developer of detail specifications. These values ​​apply when the connectors are fully mated.
For some of the tests listed, no recommended values ​​are given and these tests are not normally required. When these tests are required, the applicable values ​​are filled in the detail specification at the discretion of the specification developer. Nominal impedance
