The complete range of LMF Plugs and Sockets is catalogued on Pages 7 to 24, and all units with the same contact arrangement are shown grouped together. The units are listed in order of number of contacts and on each connector page the mating combinations are indicated. There are no other mating combinations apart from those shown thus:

The diagram above each group shows the plug pin arrangement, the contact coding and moulding characteristics of the mating face of a plug. All coding of sockets is reversed, i.e. a mirror image of the plug coding.

A feature of LMF plugs and sockets is that the internal moulding carrying the contacts may be located in any one of six radial positions relative to the major keyway in the outer shell (see diagrams at the side of each group, pages 7 to 24). This facility eliminates the possibility of mismating adjacent plugs and sockets of the same contact arrangement. The sixth position is known as 'neutral' (shown in all diagrams as orientation position 0). Unless otherwise stated when ordering, all plugs and sockets will be supplied in the neutral position. Orientated units are identified by replacing the last digit of the part number of the neutral unit with a position number. The last digit for neutral units is always 0. Only orientations of the same suffix number can be mated together.

Attention is drawn to the 3 contact 5 amp range of plugs and sockets in which only positions 0 and 5 are available as orientation variations.
