Structural Design & Signal Benefits
27 individually shielded pairs – eliminates crosstalk between channels
22 AWG tinned copper – flexible, corrosion-resistant, reliable
Polypropylene insulation – low capacitance for longer transmission
50Ω impedance – matches data communication systems
PVC jacket – durable for indoor industrial use
Installation & Performance Considerations
Max pull tension: 500 lbs (230 kg) – do not exceed
Bend radius: min 7.1 in (180 mm) – stationary and installation
Temperature: -20°C to +80°C – indoor use only
Voltage: 300V (UL CM) / 30V (AWM 2919)
Keep away from high-voltage power cables – avoid EMI
