The receptacles and plugs contain either male contacts or female contacts. The contacts fitted in the classes Y and YE receptacles are exclusively of the male non-removable solder type. The connectors are polarized by means of keyways and keys; polarization 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. Masking of the blue colour band on the receptacle provides visual indication of full coupling. 4.2 Receptacle The receptacle may be attached by:  square flange;  the jam-nut with O-ring sealing; for spare parts, see EN 2997-002;  round flange for attachment by soldering/brazing/welding, classes Y and YE only. The receptacle contains five keyways into which the keys of the plug engage. The main keyway is fixed and is wider than the others. Polarization is ensured by different positions of the secondary keyways. The position of the insert is fixed relative to the main keyway. 4.3 Plug The plug contains five keys, which engage in the keyways of the receptacle. The main key is wider than the others. Polarization is ensured by different positions of the secondary keys. The position of the insert is fixed relative to the main key. The coupling ring permanently fitted on the plug enables the connectors to be coupled and uncoupled. The coupling torque shall be at least 50 % lower than the uncoupling torque. The internal thread of the coupling ring may be treated during manufacture with a suitable lubricant compatible with the performance required in this standard. The plug of classes S, SE, RS and WS is fitted with a grounding spring device ensuring electrical continuity between the coupled connector housings.
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 Housings The material of the housing for the connectors and for the fittings may either be passivated stainless steel or aluminium alloy protected against corrosion by nickel or cadmium plating (see EN 2997-002). SIST EN 2997-001:2009

The cable outlet accessories shall compress the grommet of the connectors without twisting it. A blue colour band indicating that the crimp contacts of the connectors are intended for rear removal shall be provided:  behind the flange of the receptacles with square flange;  on the flange of receptacles for nut attachment;  on the coupling ring of the plugs. The position of the blue colour bands shall be such that at least one of them is visible at all times on the coupling ring of the plug. 5.2 Inserts The insert 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 insert for contacts shall be non-removable; it shall be mechanically held in the housing. Sealing shall be provided between the housing and insert. SIST EN 2997-001:2009
