CONNECTORS FOR ELECTRONIC EQUIPMENT – PRODUCT REQUIREMENTS – 

Part 2-101: Circular connectors – 

Detail specification for M12 connectors with screw-locking

indispensable for the correct application of this publication.

ernational Standard IEC 61076-2-101 has been prepared by sub-committee 48B: Connectors, of Technical Committee : Electromechanical components and mechanical structures for electronic equipment.

1      Scope


This part of IEC 61076 describes M12 circular connectors typically used for industrial process measurement and control. These connectors consist of fixed and free connectors either rewireable or non-rewireable, with screw-locking. The connectors with glass to metal seal are fixed connectors only which consist of fixed glass to metal sealed styles with rewireable male contacts and are intermateable with corresponding free connectors according  to this International Standard. Male connectors have round contacts Æ 0,6  mm, Æ  0,76 mm, Æ 0,8  mm and Æ 1,0 mm.


The different codings prevent the mating of these coded male or female connectors to  any  other 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      Technical information

1.1              Terms and definitions


For the purposes of this document, terms and definitions from IEC 60050-581 as well as the following apply.


3.1.1

mounting orientation

circular mounting position of the connector in relation to the polarization of the  mating interface


NOTE Where the free connector has an angled cable entry (as opposed to an  in-line cable  entry),  the  angle  between the cable entry direction and the polarization keyway should be specified.


3.1.2

glass to metal seal

a form of construction whereby the connector contacts are housed in a glass insert which is inside a metal connector shell so as to form a connector with a hermetic seal which may be used to isolate differing environments


3.1.3

matched glass to metal seal

a form of construction whereby the thermal expansion characteristics of the glass, the metallic contacts, and the connector shell are similar and the seal between the glass and the metal is formed by a chemical bond


3.1.4

compression glass to metal seal

a form of construction whereby due to the its higher coefficient of expansion  the  shell contracts around the glass  during the solidification phase of manufacture applying  a compression force to the glass insert so as to form a seal


1.2              Recommended method of termination


1.2.1                 General

The contact terminations shall be of the following types: screw, crimp, insulation piercing, insulation displacement, press-in or solder. For the male connectors havinga glass to metal seal the recommended contact terminations are crimp, eyelet, solder, PCB and rounded.


NOTE  1  eyelet –  the termination end is  flattened and pierced with a  hole to provide both mechanical retention of   the wire as well as solder attachment.





NOTE 3 PCB – termination spills suitable for insertion into printed circuits.


1.2.2                 Number of contacts or contact cavities


A-coding                                 2 to 17 contacts

B-coding                                 5 contacts

C-coding                                 3 to 6 contacts

D-coding                                 4 contacts

P-coding                                 5 contacts (4+PE)
