two rack and panel (blind mate) connector housing sizes; it is a size three housing and a size four housing which have respectively three and four insert cavities all with one keyway, three polarizing posts or keys offering 64 polarizing positions and no locking mechanism. In addition to this rack and panel use, the size four male connector can be mated with two size 2 female connectors in a disconnect application by using two centre coupling mechanisms. These connectors use different types of contacts (signal, power, coaxial, triaxial, quadrax, etc.) see EN 3155-002 and optical contacts see EN 4639-002. SIST EN 4644-001:2012

Aligning cavities guaranty not only the alignment between male and female housing but also guarantee the shell to shell bottoming. Non aligning female housing cavities have a circular location tolerance. In order to define how alignment of the female and male housing is achieved a dimension line between the two housing aligning cavities is defined. SIST EN 4644-001:2012

Figure 8 — Rack and panel male non aligning cavity (RNC) 4.4 Rear accessories See EN 4644-002. 4.5 Inserts The insert assembly shall be single-bloc type design complete with contact retention systems and appropriate seals. The female inserts use female contacts and male inserts use male contacts. These inserts use contacts of size 22, 20, 16, 12, 8 and 5. The inserts are rear release rear removable from the housing. Male and female inserts can be installed either in the male or female housing. There are inserts with one polarizing rib (A polarizing position) and inserts with two polarizing ribs (B polarizing position). This means that there are inserts dedicated to housing cavities with one keyway and inserts dedicated to housing cavities with two keyways. See Table 1 below. SIST EN 4644-001:2012

A blank insert is installed in a housing cavity where no contact is required. This blank insert has no polarizing rib and the same dimensions as an insert for pin contacts. It can be installed in any male or female housing cavity. This blank insert can mate without causing any interference with an insert for male contacts or with an insert for female contacts. The blank insert does not provide sealing. 4.6 Keying mechanism Size 1, 3 and 4 housings have a polarizing system using polarizing posts having a L shape cross section and polarizing keys having a L shape cavity to mate with the polarizing posts. Each polarizing post and key provides 4 polarizing positions. Each post and key is retained in the housing by a special shape which allowed them to be clipped in the housing. Size 1 housings have two polarizing pins offering 16 polarizing positions. Size 3 and 4 housings have three polarizing pins offering 64 polarizing positions.
The size 2 housing has either a centre coupling screw or coupling nut which ensure also the polarizing function. The coupling screw has a coding peg and the coupling nut has a coding slot. The centre coupling screw and nut have an hexagonal shoulder which slides in an hexagonal print in the housing, consequently, the coupling screw or nut can take 6 positions. The coding peg on the coupling screw and the slot on the coupling nut can be vertically aligned with an angle or a flat of the hexagonal shoulder. There are two types of coupling screw and coupling nut, those having the coding peg or the slot aligned with a flat and those for which it is aligned with an angle of the hexagonal shoulder. These two types of coupling screw and nut provide a total of 12 polarizing positions. The size 4 male connector can have two centre coupling screw or coupling nut in order to be mated with two size 2 disconnect female connectors. 4.7 Dust caps See EN 4644-002. 4.8 Materials and surface treatment 4.8.1 General When dissimilar metals are in close contact, adequate protection against corrosion shall be used in order to make sure that the electromotive force of the cell shall not exceed 0,25 V. 4.8.2 Housings The material of the housing shall be aluminium alloy or composite. When aluminium is used, it shall be protected with nickel plating or aluminium chromatation (see EN 4644-002). Composite housings are nickel plated. SIST EN 4644-001:2012

 Inserts with two polarizing ribs. Inserts with one polarizing rib shall fit the cavities of housing size 1, 3, 4 and cavity A of housing size 2. Inserts with two polarizing ribs shall fit the cavity B of housing size 2. The inserts shall be rear removable from the housing and shall be mechanically retained in the housing. The removal of an insert shall be done by using the tool described in product standard (see EN 4644-002). An insert is installed in the housing by hand, it is a rear snap in insert. The mating face of the insert shall ensure that sealing is provided when connectors are mated together. The interfacial seal shall be on the insert having male contacts and shall not be removable. The rear grommet shall permit sealing for all cable diameters indicated in EN 4644-002 and shall not be removable. For size 5 and height contacts, the insert contact cavity and the grommet shall accept the sealing boots described in EN 4530-002. The mechanical contact retention system shall be integrated in the rigid part of the insert. SIST EN 4644-001:2012
