Belden Inc. 3112A0045000 Single Pair 20 Awg Pvc Cable

Product Description

The BELDEN INC. 3112A0045000 is a single-pair shielded instrumentation cable designed for signal transmission in industrial and commercial control applications. Built around a 20 AWG conductor configuration with PVC insulation and jacketing, this cable is suited for low-voltage analog and digital signal runs where reliable shielding and consistent impedance matter. Licensed electricians and instrumentation technicians typically install this cable in panel wiring, sensor loops, and process control circuits where signal integrity is critical.

This cable is commonly used in light industrial, commercial building automation, and process control environments. Its foil-shielded pair construction supports clean signal transmission over longer runs, reducing interference from adjacent power conductors. Typical applications include HVAC control wiring, thermocouple extension, RTD circuits, and general low-level signal interconnect work where a single shielded twisted pair is specified.

Key Features

• Single foil-shielded pair construction for noise rejection in signal circuits
• 20 AWG conductor size suitable for low-current instrumentation and control runs
• PVC insulation and jacket rated for standard indoor control wiring installations
• Sold as individual unit (each), suitable for cut-to-length ordering

Compatibility

Designed as a standard single-pair shielded instrumentation cable for use in control panels, building automation systems, and process instrumentation wiring where a 20 AWG PVC-jacketed shielded pair is specified.

Installation Notes

Installation should be performed by a licensed electrician or qualified instrumentation technician in accordance with NEC Article 725 or applicable local codes. De-energize all control circuits before terminating or splicing. Maintain drain wire continuity and ground the shield at one end only to prevent ground loops in sensitive signal circuits. Avoid routing signal cable in the same conduit or tray as high-voltage power conductors where possible.
