Introduction
This family of connectors is derived from MIL-DTL-38999 series III, with which it is intermateable and
interchangeable. It is particularly suitable for use in zones of severe environmental conditions on board
aircraft, applying EN 2282.
1 Scope
This European Standard specifies the general characteristics, the conditions for qualification, acceptance and
quality assurance, as well as the test programs and groups for threaded ring coupling circular connectors, fire-
resistant, intended for use in a temperature range from – 65 °C to 175 °C continuous or 200 °C continuous
according to the classes and class.

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.
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.
The coupling ring shall be designed so that the male and female contacts engage when it is turned in a
clockwise direction and disengag
