Defence Standard 61-12 Pt 4 & Pt 5 Multicores
These are produced as sub-miniature with a conductor size of 7/0.2mm (Pt 4) and a maximum current of 1 amp or
with a conductor size of 16/0.2mm (Pt 5) and a maximum current of 2.5 amps. If a current greater than 2.5 amps is
needed a conductor size of 37/0.315mm is used with up to 4 cores. In this case the current should not exceed 13 amps.
The cables are produced unscreened and either individually or overall screened.
The screening is with a tinned copper braid. The insulation is Type 2 PVC for 7/0.20 mm conductor and Type TI1 PVC
for the 16/0.20mm and 37/0.315mm conductors. The sheathing compounds are PVC type TM2.
The cables are also available in heat resisting PVC by quoting the reference number and duplicating the final letter.
e.g heat resisting version of 7-2-2A is 7-2-2AA
The maximum voltage for these cables is 440 volts rms at frequencies up to 1.6Khz.
These cables are used for instrumentation purposes,data processing, computers and other electronic equipment.
