Belden Unscreened Twisted-Pair Data Cable, 20AWG, 304m Length - 8205NH.00305 For reliable data transmission in network and communication systems, choose this data cable from Belden. It's insulated with polyvinyl chloride (PVC), so it's resistant to corrosion, oils and moisture. The cable's conductors have a twisted pair arrangement to prevent electromagnetic interference (EMI), giving you clear and reliable signal transmission. A low smoke zero halogen (LSZH) sheath means toxic fumes won't be emitted in the event of a fire, while polyethylene (PE) insulation prevents the risk of electric shocks. A data cable like this one is often used to transmit video from a security camera to a recording device. Features & Benefits • Chrome-coloured sheath makes it easy to distinguish from bright or dark coloured cables
• Wide operating temperature range of -15°C to +80°C for use in demanding industrial environments
• Flame retardant properties means the risk of fire spread is minimised Applications • Computer systems
• Telephone lines
• Sound systems What's the difference between shielding and screening? Shielding reduces electrical noise and prevents crosstalk between cables that are close to each other. Screening also prevents electrical noise, but its main purpose is to limit signals from escaping the cable.
