2 Core 20 AWG Shielded Multi Conductor Control Cable ( PER METER )

A 2-Core 20 AWG Shielded Multi-Conductor Control Cable is a general-purpose electronic cable designed for transmitting low-voltage signals and data while providing protection against electrical interference.

It is commonly used in industrial process control, security systems, audio/public address systems, and computer interconnections (like RS-232 applications).

Technical Specification

Technical Specifications

1. 2-Core (Conductor Count)

Structure: It contains two separate inner conductors (cores) twisted together to form a pair. This twisting helps reduce electromagnetic noise susceptibility between the two lines.
Purpose: The two cores are used to carry a signal and its return, or for a low-voltage DC power connection (positive and negative).

2. 20 AWG (Wire Gauge)

Size: The conductors are 20 AWG (American Wire Gauge). This is a moderately small gauge, suitable for signal transmission and carrying low-current power over short to moderate distances.
Material: Conductors are typically made of stranded tinned copper for flexibility and resistance to corrosion, though solid copper options exist.

3. Shielded (Interference Protection)

Shielding: The two conductors are wrapped in a metallic shield (usually aluminum foil with a polyester backing, often with a copper braid layer, or a combination).
Function: The shield protects the internal signal wires from Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI), which are common in industrial and electronic environments. The shield is connected to a drain wire that is connected to a ground connection at one or both ends of the cable run to safely dissipate noise.

4. Multi-Conductor Control Cable (Application)

Function: This is a versatile cable category used for electronic circuits, control systems, and instrumentation.
General Rating: It typically carries a maximum voltage rating of 300V to 600V and is constructed with a durable outer jacket, often PVC (Polyvinyl Chloride) or LSZH (Low Smoke Zero Halogen).
