APPLICATION:
Our 18/16 Pair (32-Conductor) Shielded TC-ER Instrumentation Cable (600V) is suitable for control, instrumentation and process control circuits, where protection against electrostatic interference from both outside of the cable and from pair to pair is needed. TC-ER Shielded Pairs with Overall Shield (SPOS) cables are suitable for wet or dry applications, direct burial, indoor or outdoor locations, installed in cable trays, ducts, aerially or conduits and for applications up to 600 volt and temperatures up to 90°C. TC-ER SPOS Instrumentation Cables are suitable for use in Class 1 Division 2 Hazardous locations per NEC.
CONDUCTORS:
Stranded soft drawn bare copper conductor, per ASTM B3 & B-8
INSULATION:
Polyvinyl Chloride (PVC) insulation with a nylon overcoat
JACKET:
Polyvinyl Chloride (PVC) jacket, which is water, chemical, sunlight and abrasion resistant
COLOR CODE:
Black & White numbered pairs
SHIELD:
Aluminum polyester foil with 100% coverage on each pair, with an overall aluminum polyester foil with 100% coverage with a tinned copper drain wire in contact with all shields
"Consolidate 16 independent signal loops into a single, high-performance pull—engineered with individually shielded pairs and an overall foil shield for maximum EMI protection in high-density control arrays."
Why Engineers Specify Our 18/16 Pair Cable
This heavy-duty 32-conductor (16-Pair) instrumentation cable is the industrial standard for centralized process monitoring and large-scale DCS hubs. It allows you to manage 16 independent process loops (such as 4-20mA signals) within a single, ruggedized jacket, drastically reducing the complexity and footprint of your cable tray systems.
Maximum Signal Isolation (SPOS): Each of the 16 pairs is wrapped in its own 100% aluminum polyester foil shield, then protected by an overall foil shield. This "Shielded Pairs with Overall Shield" construction ensures that 32 conductors can operate in close proximity with zero signal bleed or data corruption.
Massive Labor Efficiency (TC-ER): Rated for Exposed Run (ER), this cable is UL-listed for installation without conduit or raceways. One pull replaces 16 individual cables, cutting your installation time by up to 70% and eliminating miles of expensive pipe infrastructure.
Hazardous Environment Ready: Fully compliant with Class 1 Division 2 requirements. The chemical, sunlight, and moisture-resistant PVC/Nylon jacket is designed for the extreme conditions of refineries, chemical plants, and offshore rigs.
Precision Numbering: Every pair is clearly numbered 1 through 16 (Black & White), ensuring fast, error-free termination in high-density control cabinets.
More Common Applications
Centralized DCS & PLC Hubs: Connecting large sensor banks (Pressure, Flow, Level) to a main industrial control room.
Petrochemical & Refining: Managing high-density multi-valve and multi-motor feedback in hazardous zones.
Power Generation: Critical signal wiring for large-scale turbines and complex monitoring systems.
Large-Scale Infrastructure: Reliable, consolidated signal transmission for bridges, tunnels, and water treatment plants.
