DEF-STAN
Multicore cables to UK Ministry of Defence Standards have been used for the interconnection of electronic equipment for many years to transmit data over short distances, and where environmental conditions are such that interference does not present a problem.
DEF STAN 61-12
Miniature cables are manufactured in accordance with DEF STAN 61-12 part 5 using 16/0.2mm tinned copper conductors, Sub-miniature cables are manufactured in accordance with DEF STAN 61-12 part 4 using 7/0.1 and 7/0.2mm tinner copper conductors .
These cables are utilised for signal transmission within a variety of applications, including process and data communications, for the interconnection of equipment and instruments.
In situations where signal integrity is a consideration, tinned copper wire braid screened and sheathed cables (C types) are available to combat EMI (electromagnetic interference) with the braid itself being occasionally used as the grounding point. The standard also includes a version with individually screened cores (D type) but this is very unpopular and is no longer a stock item for Belcom. Overall foil screened versions (S type) are available and include a tinned copper drain wire. The majority of applications currently use screened versions although where screening is not a consideration the standard cable (A type) can be used.
