3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 2591-100 apply.
4 Description
4.1 General
Different variants of materials, housings and contact arrangements are provided according to the classes
depending on the service conditions.
The pair of connectors is characterised:
 by shell to shell bottoming;
 by its triple threaded and self-locking coupling system;
 by plugs with shielding ring providing protection against radioelectrical interference;
 by the scoop-proof shells.
These connectors use the following contacts:
 crimped sizes 22, 20, 16, 12, 10 and 8;
 soldered (model Y) sizes 22, 20, 16 and 12;

 coaxial crimped or soldered sizes 16, 12 and 8;
For arrangements comprising the letter G, all
 triaxial crimped or soldered size 8;
contacts are grounded to the receptacle housing
 quadrax crimped size 8.

The receptacles and plugs contain either male contacts or female contacts.
The contacts fitted in the class Y receptacles are exclusively of the male solder type.
The connectors are polarised by means of keyways and keys; polarisation shall be obtained before the male
contacts enter the insert of the female contacts and before the coupling ring is engaged. The position of the
keying arrangement is given in Table 5.
The visual check of coupling is obtained by masking of a red colour band on the receptacle.
4.2 Receptacle
The receptacle housing may be attached:
 square flange;
 nut, with sealing by O-ring at the attachment;
 round soldered or brazed flange for class Y connectors.

---------------------- Page: 8 ----------------------

SIST EN 3645-001:2014
EN 3645-001:2013 (E)
4.3 Plug
The coupling ring is permanently fitted to the plug and allows coupling and uncoupling of the connectors. The
lanyard release version may also be uncoupled by pulling on the lanyard.
The plug is fitted with a self-locking mechanism and a grounding spring device ensuring electrical continuity
between the coupled connector housings.
An anti-decoupling device shall be provided to maintain complete coupling.
4.4 Materials and surface treatment
4.4.1 General
When dissimilar metals are in close contact, adequate protection against corrosion shall be used for the
electromotive force of the cell not to exceed 0,25 V (see EN 3197).
4.4.2 Housing
The material of the housings for the connectors and fittings may be either aluminium alloy, passivated
stainless steel or composite. Aluminium alloy and composite shall be plated as defined by the class
(composite coupling rings and Hex nut may be unplated) (see EN 3645-002).
4.4.3 Contacts
Unless otherwise specified, the non-removable contacts shall be in ferrous alloy for class Y and in copper
alloy for the other classes.
They shall be gold-plated on an appropriate undercoat. Selective protection is authorised provided that it is
sufficient to ensure that the specified performance is achieved.
Measurement of the thickness of the protective plating shall be effected in accordance with ISO 4524-1.
For removable contacts, see EN 3645-002.
4.4.4 Non-metallic materials
The materials used for insert, seals and grommets shall have a hardness and mechanical and electrical
characteristics consistent with the required use.
5 Design
5.1 Housings
The connector housings shall be one-piece. They shall contain teeth at the rear over their entire periphery and
shall accommodate the rear accessories. The receptacle shall be fitted with a seal for sealing the coupled
housings.
Jam nut receptacles shall contain an O-ring seal. The nut shall have holes for the passage of locking wire.
During coupling the grounding spring shall be engaged a minimum of 1,02 mm in the receptacle before the
contacts engage.
Except for the triple start threads, which shall conform to standard MIL-STD-1373, threads shall conform to
standards ISO 68-1, ISO 261, ISO 262 and ISO 965-2.

---------------------- Page: 9 ----------------------

SIST EN 3645-001:2014
EN 3645-001:2013 (E)
The coupling ring shall be designed so that the male and female contacts engage when it is turned in a
clockwise direction and disengage when turned anticlockwise. The coupling threads may have a lubricant
applied during manufacture.
Full locking of the connectors shall occur at about 360°. On completion of tightening of the coupling ring,
mechanical contact shall exist between the receptacle and plug housings. A red band shall be located on the
receptacle so as to be visible when unmated and fully covered when completely mated.
The receptacle has five keyways which engage with corresponding keys on the plug. The major key is fixed
and is wider than the others. Polarisation is ensured by the different positions which the minor keys may take.
The position of the insert is fixed relative to the major key.
A blue-coloured band indicating that the crimped contacts of the connectors are rear-releasable shall be
provided:
 in front of the flange on square flange receptacles;
 on the flange of jam nut receptacles;
 on the coupling ring of plugs.
This band shall be positioned so that at least one is visible when the connectors are fitted and when they are
mated or unmated. Hermetic receptacles do not require blue colour band.
5.2 Inserts
The insert for contacts shall be non-removable; it shall be mechanically held in the housing. Sealing shall be
provided between the housing and insert.
The front face of the insert shall be such that sealing is ensured when the connectors are coupled. The
interfacial seal of the insert of the male contacts shall be bonded on the hard insert.
The grommet shall permit sealing for all cable diameters indicated in EN 3645-002 and shall not be
removable.
The mechanical contacts retention system shall be integrated in the hard insert.
The design of non-hermetic connectors shall permit individual installation of the contacts without removal of
the insert or grommet. Fitting and removal of the contacts shall be from the rear with the tools specified in the
contact product standards.
Contact position identification shall be permanent and contrasted on the front face of the insert or the
interfacial seal and on the rear face of the grommet as indicated in 6.6.
The marking shall not be recessed or raised on the surfaces providing a seal.

6.6 Contact arrangements
The contact arrangements in the inserts are specified by Figures 7 to 75, which show the front face of male
inserts.
The following tolerances are applicable to the inserts fitted in the housing:
 centre of the entry diameter of each female insert (diameter R, Figure 1):

∅ 0,38 M D − 0,05 M G − 0,15 M

 centre of the end of each male contact:

∅ 0,61 M D − 0,05 M G − 0,15 M


D and G are given in Figure 3.
Arrangements comprising coaxial or triaxial contacts grounded to the shell (identified by the letter G) are not
applicable to plugs.
Arrangement comprising Quadrax contacts are identified by letter Q when these contacts are grounded to the
shell, and by letter L when not grounded.
Arrangement comprising reinforced inserts for power contacts are identified by letter R.
Arrangement comprising reinforced inserts for fluids are identified by letter K.
