Specifications
Conductors:  Bare soft annealed copper, Class B, 7-strand concentric per ASTM B-8.

Insulation:  Flame-retardant Okoseal (PVC) per UL 13 and UL 2250, 15 mils nominal thickness, 105°C temperature rating.

Conductor Identification:  Pigmented black and white in pairs, black, red and white in triads.

Assembly:  Pair or triad assembled with left-hand lay.

Jacket:  Black, flame-retardant, low temperature Okoseal per UL 13 and UL 2250. A rip cord is laid longitudinally under the jacket to facilitate removal.

Classifications
UL Listed as Type ITC/PLTC - Instrumentation Tray Cable/Power Limited Tray Cable for use in accordance with Article 727 and Article 725 of the National Electrical Code.
 
These cables comply with UL 2250 and UL 13 for PLTC, CL2 and CL3.

Applications
Okonite Type P-NS (Pair/Triad - No Shield) instrumentation cables are designed for use as instrumentation, process control, and computer cables in ITC non-classified or labeled circuits up to 150 volts and 5 amps (750VA) and in Class 2 or 3 Power-Limited circuits where shielding against external interference is not required; indoors or outdoors; in wet or dry locations with conductor operating temperatures up to 105°C; in cable trays, in raceways; supported by a messenger wire; for direct burial. Suitable Class I, Division 2, Class II, Division 
2, or Class III, Division 2 hazardous locations. Also for use as Power-Limited fire protective signaling cable (FPL) per NEC Code 760.

These cables are intended for use where no shielding is required from external interference.

For dc service in wet locations, X-Olene insulation having an overall aluminum C-L-X armor construction is recommended.
