4 Description
4.1 General
4.1.1 Introduction
Different variants of materials, housings, modules and contact arrangements are provided according to
the Class depending on the service conditions.
These connectors have rectangular housings, with removable modules and contacts. They can be fitted
with cable outlets. Male or female modules can be inserted or intermixed in plug or receptacle housings.
These connectors use different types of contacts (signal, power, coaxial, quadrax, optical, …) defined in
EN 3155-002.
These connectors can also be fitted with optical modules EN 4701 and EN 4830 with associated optical
contacts.
This specification covers three variations in housing and coupling mechanisms to mate and unmate:
— centre coupling screw;
— rack and panel;
— push-pull latching.
4.1.2 Centre coupling
The connectors are mated and unmated by a centre coupling screw, which provides when the connectors
are fully mated a shell to shell bottoming between plug and receptacle.
The plug contains a coupling screw and the receptacle a coupling nut.
This family of connectors provides two housing sizes (2 or 4 modules) and two series (series 2 and scoop
proof series 3).
The connectors are polarized by centre keying mechanism; polarization shall be obtained before the male
contacts enter the module of the female contacts and before the coupling system is engaged. Keying
mechanism shall provide 36 position keying capabilities.
4.1.3 Rack and panel plug
The rack and panel plugs contain a clipped centre coding socket clipped with internal keyways.
Polarization is ensured by the different positions which the secondary keyway may take and different
positions which the centre coding socket may take clipped in the housing.
The centre coupling screw is replaced by a centre guide pin. The floating fixation with coupling spring
ensures the alignment and the metal to metal bottoming between plug and receptacle.
4.1.4 Push-pull latching
The connectors are mated and unmated by a push-pull latching mechanism (for more detail, see 4.3.2 for
receptacle and 4.4.4 for plug).
This family of connectors provides single housing size (1 module series 2).
The connectors are polarized by integral key and keyways mechanism associated with dedicated colour
identification.
Polarization shall be obtained before the male contacts enter the module of the female contacts and
before the coupling system is engaged.

prEN 4165-001:2023 (E)
4.2 Housing
All parts except module are considered “housing”.
All “housings” models, except class C, shall meet electrical performances described in Table 39.
4.3 Receptacle
4.3.1 Centre coupling mechanism
The receptacle may be attached by:
— Rectangular flange with two mounting holes;
— Two end flanges with transversal holes (panel mounting) and lateral holes (stackable mounting).
The receptacle contains a coupling nut which ensures also the polarization function (coding pin) by
external keys. The main key fixed and is wider than the other. Polarization is ensured by the different
positions which the secondary key may take and different positions which the coding pin may be fixed in
the housing.
The module cavities are identified on the housing of the receptacle by letter A, B, C, D for size 4 (four
modules) and letter A, B for size 2 (two modules). The cavities are polarized by two keyways location.
4.3.2 Push-pull latching mechanism
The receptacle can be attached by rectangular flange.
The receptacle shell design incorporates specific design feature that provides a mechanical and electrical
interface to the plug. The electrical ground path established by the mounting design feature incorporated
in the receptacle shell maintains a stable, low resistance electrical ground path for the life of the
installation. This electrical ground path that is provided by the mechanical mounting feature shall require
no preparations during the initial assembly processes or maintenance once in service.
4.4 Plugs
4.4.1 General
The plugs contain a clipped centre coding socket clipped with internal keyway options. Polarization is
ensured by the different positions which the secondary keyway may take and different positions which
the centre coding socket may take clipped in the housing.
4.4.2 Centre coupling mechanism
The coupling screw permanently fitted on the plug enables the connectors to be coupled and uncoupled.
The internal thread of the coupling ring may be treated with a suitable lubricant compatible with the
performance required in this standard.
The module cavities are identified on the housing of the plug by letter A, B, C, D for size 4 (four modules)
and letter A, B for size 2 (two modules). The cavities are polarized with two keyway locations.
4.4.3 Rack and panel
The plug contains a clipped centre coding socket clipped with internal keyway options. Polarization is
ensured by the different positions which the secondary keyway may take and different positions which
the centre coding socket may take clipped in the housing.
The centre coupling screw is replaced by a centre guide pin. The floating fixations with coupling spring
ensure the alignment and the metal to metal bottoming between plug and receptacle.

4.4.4 Push-pull latching mechanism
The plug shell is mated to the receptacle shell by sliding the plug into the receptacle where the two shells
engage. The latch mechanism then engages the specific features located on the receptacle forcing the two
connectors shells together creating a mechanically rigid assembly. The receptacle shell shall contain
design features that interface to the plug shell providing not only a mechanically rigid assembly but a
360 degree enclosure essential to the EMI shielding performance. The coupling mechanism and
connector shell design shall incorporate a means of providing a visual reference that the plug is fully
mated to the receptacle. No tools shall be required to activate and release the latch mechanism to either
mate or unmate the plug to the receptacle. The coupling mechanism shall withstand 500 mating and
unmating cycles. This mechanism shall be self-lockable.

The rear accessories used with this family are
