The connectors are polarized by means of keyways and keys. When all the male contacts are in place, polari-zation is obtained by different angular positions of the insulator in relation to the main slot or locking key andshall occur before the coupling ring can carry out its function.
The visual check of coupling is obtained by viewing the locking pins through the inspection holes in thecoupling ring of the plug.
The plug contains five keys which engage in the keyways of the receptacle. The main key is wider than theothers.Polarization is ensured by the different angular position of the inserts.
The coupling ring permanently fitted on the plug enables the connectors to be coupled and uncoupled.The in-ternal guides of the coupling ring may be treated with a suitable lubricant compatible with the performance re-quired in this standard.
The plug of models RS and wS is fitted with a grounding spring device ensuring electrical continuity betweenthe coupled connector housings.BS EN 3646-001 pdf download.
