Outstanding Electrical Performance

The BELDDEN 533945 provides a low mutual capacitance of 42 pF/m at 1 kHz and an impedance of 120 Ohms. This ensures minimal signal attenuation (3.2 dB/100m at 1 MHz) and reliable data transmission over long distances. Its dielectric strength of 2000V AC/1min further adds to operational safety and integrity.

Superior Noise Rejection and Shielding

With shielded twisted pair construction and an aluminum foil shield plus drain wire, the cable delivers excellent noise immunity. This makes it ideal for environments with high electrical interference, such as industrial automation and RS-485 communication lines.

Robust Construction for Industrial Use

The 24 AWG stranded tinned copper conductors, combined with flexible PVC insulation and jacket, provide resilience against mechanical stress. Oil resistance, flame retardance (VW-1), and a bend radius of 10X cable diameter make BELDDEN 533945 suitable for both fixed and flexible installations.
