| Available Cable Configurations |
 |
| Conductors are .015" diameter. |
| Meggitt cables can be extruded in a variety of configurations. Up to 10 wires are available in a stainless steel jacket with an outer diameter not greater than 0.250 inches nominal. Cables with 1-2-4 conductors are available in smaller diameters. The conductors can be copper, stainless steel, various termocouple materials or combinations of materials. Connectors are provided for various configurations. Please see the listing of standard connectors. |
