Belden Coaxial Cable, Black PVC Sheath, 20AWG - 8259 Series - 8259 0101000

When signal strength is a priority, choose this coaxial cable from Belden. Thanks to its 50Ω impedance, it safeguards signal integrity while fine-tuning transmissions. A durable PVC jacket is on hand to resist impact and abrasion in heavy-duty settings, while tinned-copper braid shielding protects against interference to ensure noise-free transmission. The cable's supplied unterminated in a length of 305m, so you can make long runs or cut it down to the exact size you need.

Features & Benefits

• Operating temperature range of -30°C to +75°C means it stands up to challenging conditions

• Low weight of 11kg per 305m of cable, so it's easy to carry and install

• Tinned-copper wire is highly conductive for strong signals

• 50.8mm minimum bend radius means it handles twists and turns

Applications

• Wireless communication networks

• CCTV systems

• Medical imaging

How thick is this cable?

It has a compact outer diameter of 4.9mm so it's flexible enough to fit into awkward spots.
