Shielded Signal Control Cables

Pairs (NTQ Series)
RFI Shielded Cables
Meets U.L. Style 2343 or 2344 for Computer Use
National Wire & Cable Corp. manufactures a complete line of flexible signal and control cables in which each quad is individually shielded and plastic-jacketed. Conforming to MIL-C-27072, these cables provide extended temperature, rough usage, military shielding, excellent flexibility. Provides a minimum of crosstalk between signal channels, plus complete isolation between shields. Excellent for analog signals. All jackets are moisture proof and suitable for use in duct, conduit, aerial, or burial installations.
Conductors are stranded tinned copper with .010” vinyl primary insulation plus .004” nylon insulation over the vinyl per MIL-DTL-16878/17. Insulation for 600 Volts working rating at 105°C. Color-coding: Quads - Black, White, Red, and Green. All conductors are 19 strand.
Shielding is tinned copper braid with 85-90% coverage per MIL-C-7078, and shield angle below 40 degrees for easy pushback.
Type F. Each subcable is individually identified by color code per MIL-STD-681, starting with color #9.
All sub-components are planetary cables and contra-helically laid with a mylar tape serve over the cable bundle. The overall sheath is abrasion-resistant black 105°C vinyl thermoplastic per MIL-I-631, Type F.
Optional overall shielding of cabled bundle is 85-95% minimum coverage of tinned copper braid applied per MIL-C-7078 over the tape serve under sheath.
