4 Conditions of use
Operating voltage: see EN 2282
5 Description
5.1 General
A pair of connectors is characterized by its rectangular shell, its screw coupling system located at both ends
and by the inserts which can be removed from the shell.
The shells provide polarization of the coupling as well as locating and polarizing of inserts.
The male contacts are rectangular in cross-section and female contacts are of the tuning-fork type; their size
is comparable to a size 22 or 20 circular contact, according to the individual case.
These connectors use removable crimp contacts, sizes 20 and 22, or non-removable solder contacts size 22.
Receptacles and plugs can accommodate inserts containing either male or female contacts. When male
contacts are fitted in the plug, the connector is "scoop-proof".
The inserts can be removed from the shell.

SIST EN 3218-001:2009
EN 3218-001:2006 (E)
Coding, carried out by the user, is provided by two removable keys located at each end of the housings and
capable of assuming four positions, thus giving 16 coding options.
Different configurations of housings and contact arrangements are provided in EN 3218-002.
There are two sizes of housing (size 1 and size 2).
5.2 Materials
The materials used shall be corrosion-resistant. When dissimilar metals or alloys are in close contact,
adequate protection shall be provided so that the electromotive force of the galvanic couple shall not exceed
0,25 V.
The contacts shall be covered with a gold plating over a nickel undercoat.
The thickness of the gold shall be at least 1,27 µm in the active zone of the contacts.
The housings shall be made of aluminium alloy with, according to the version, the following finishing:
anodized coating: code A;
cadmium plating: code C;
nickel plating: code N.
The threaded items and accessories shall be made of stainless steel.
The materials used shall satisfy the requirements of the mould growth test (EN 2591-306).
6 Design
6.1 Housings
The housings can take one or two inserts, their position are identified by the letters A and B. One or other of
these inserts may be replaced by a dummy insert or by an insert not fitted with its contacts.
6.2 Accessories
The receptacle and plug housings shall have a cable-clamp fitting.
6.3 Sealing
Sealing shall be provided at the rear of the contacts by an elastomer seal in the case of crimp contacts or by a
heat-shrinkable sleeve in the case of solder contacts.
At the interface, a seal located on the insert holding the male contacts, shall provide sealing at the coupling.
6.4 Polarization of housings
Polarization of the receptacle and plug is achieved by the mating faces of the housings being non-symmetrical.
Polarization of A and B inserts is achieved by non-symmetry of the inserts and the internal face of the
housings.

6.5 Mounting of receptacles
The receptacles are panel mounted, either rear mounted or side mounted.
In the case of rear mounting, washers shall be used to compensate for differences in panel thickness. The
assembly drawings shall be included in the product standards for the different versions.
6.6 Threads
Threads shall comply with FED-STD-H28.
Screws shall be self-locking.
6.7 Contact characteristics
See EN 3155-001.
Solder contacts are an integral part of the insert.
Crimp contacts shall be removed from the insert from the rear.
6.8 Identification of contacts and inserts
Contacts: the position of contact No. 1 in the row shall be identified on the front face of the insert by marking
with a contrasting colour. Identification of contacts or cavities shall be done on a side face or the rear face of
the insert.
Rows: the side faces A and B of inserts and housings shall be marked.
