22、variants of materials, housings, modules and contact arrangements are provided according to the models depending on the service conditions. These connectors are rectangular housings, removable modules and contacts can be fitted with rear accessories. Male or female modules can be inserted or intermi
23、xed in plug or receptacle housings. The connectors are mated and unmated by a center 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 connect
24、ors provides two housing sizes (2 or 4 modules), two series (series 2 and scoop proof series 3) and two mating-unmating systems (screw or rack and panel). The connectors are polarised by centre keying mechanism; polarization shall be obtained before the male contacts enter the module of the female c
25、ontacts and before the coupling system is engaged. Keying mechanism shall provide 36 position keying capabilities. These connectors use different types of contacts (signal, power, coaxial, .) defined in EN 3155-002. 4.2 Receptacle The receptacle may be attached by: - rectangular flange with two moun
26、ting holes; - two end flanges with transversal holes (panel mounting) and lateral holes (stackable mounting). The receptacle contains a centre 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 ensu
27、red 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, Cl D for size 4 (four modules) and letter A, B for size 2 (two modules). The c
28、avities are polarized by two keyways location. 4.3 Plug The plug contains a centre coupling screw and a clipped centre coding socket with internal keyways. The main keyway is wider than the others. Polarization is ensured by the different positions which the secondary keyway may take and different p
29、ositions which the centre coding socket may take, clipped in the housing. The coupling screw permanently fitted on the plug enables the connectors to be coupled and uncoupled. The screwing up torque shall be lower than the unscrewing torque. The internal thread of the coupling ring may be treated wi
30、th 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, BI C, D for size 4 (four modules) and letter A, B for size 2 (two modules). The cavities are polarized by two keyways location. The plug could
31、 be fitted with a grounding device ensuring electrical continuity between the coupled connector housings. In this case the letter G made the difference beetween plugs with or without grounding system (see product standard). The model J and M are always equiped of a grounding system. Copyright Associ

33、rnal 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 center coupling screw is replaced by a centre guide pin. The floatting fixation with coupling spring ensure
34、 the alignment and the metal to metal bottoming between plug and receptacle. 4.5 Rear accessories The rear accessories used with this family are specified in product standards (see EN 4165-002). 4.6 Modules The module assembly shall be single-bloc type design complete with contact retention systems
35、and appropriate seals. The female modules use female contacts and male modules use male contacts. These modules use crimp or solder contacts of sizes 22, 20, 16, 12 and 8. They are rear release and held in the housing by two retention tines. They are from the rear with a specific tool. The modules h
36、ave two keys which engage in the keyways of the housing. Polarization is ensured by the different positions which the secondary keys may take. The module are identified by letter A, B, C, D or N (universal). A blank module is installed in a cavity where no contacts are required. This module is a mal
37、e module with a universal polarization (N) installable in all coding cavities (A, B, C, D) and in all housing types (plug or receptacle). Modules shall be interchangeable in cavities of housing with different configurations. 4.7 Keying mechanism 4.7.1 Coding pin (receptacle) Keying mechanism shall p
38、rovide 36 position keying capabilities. These 36 positions are given with 6 different coding pins, identified by colour code. The main key is wider than the other, polarization is ensured by the different positions which the secondary key may take. Universal coding pin is compatible with all polariz
39、ation codes, Coding pin shall be interchangeable in different housing models. They are fitted in the housing with a specific tool and the modification of coding position shall be made by the front face of the connector with specific tool. 4.7.2 Clipped coding socket (plug) Keying mechanism shall pro
40、vide 36 position keying capabilities. These 36 positions are given with 6 different coding socket, identified by colour code. The main keyway is wider than the other, polarization is ensured by the different positions which the secondary keyway may take. Universal coding socket is compatible with al
41、l polarization codes. Coding socket shall be interchangeable in different housing models. They are front clipped in the housing without specific tool and the modificading of coding position shall be either made by the front face of the connector with a new coding pin (a removed coding socket is not
42、reusable). 4.8 Materials and surface treatment 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. 4.8.1 Housings The material of the housing for the connectors shall be aluminium alloy or comp
43、osite, protected against corrosion by nickel or cadmium plating (see EN 4165-002).

They sh
45、all accommodate the rear accessories and other fittings defined in this specification (see EN 4165-002). The rectangular flange receptacle can furthermore be fitted with a conductive gasket ensuring electrical continuity between the connector housing and panel. The threads shall conform to IS0 263.
46、The coupling mechanism shall be designed so that the male and female contacts engage when it is rotated clockwise the right and disengage when it is rotated anticlockwise to the left. The centre coupling screw shall be a hexagonal socket head screw and compatible with the coupling torque values defi

The accessories shall be fixed by screw or clip on the rear of connectors. 5.2 Modules The module carrying the male and female contacts shall be in hard material and have a cross section and radii such that no cracks, flaking or breaks can occur in normal operation. The
48、module for contacts shall be removable; it shall be mechanically held in the housing by two retention tines periphical sealing can be provided between the housing and modules.
