This 24AWG 1 pair screened cable is a Belden 9841 equivalent, designed for low-voltage signal and data transmission where consistent impedance and protection from interference are required. It features a combination of foil and braid screening, making it suitable for installations in electrically noisy environments.
The cable uses stranded tinned copper conductors with PE insulation, providing stable electrical performance. The LSZH outer sheath is rated to Euroclass Eca, making it suitable for internal installations where reduced smoke and halogen emissions are required.
Typical applications include:
- RS-485 and serial data communication
- Industrial control and automation systems
- Audio and signal transmission
- Building management systems (BMS)
- Instrumentation and low-voltage data circuits
The dual screening (overall aluminium foil with drain wire and high-coverage tinned copper braid) helps reduce electromagnetic interference (EMI), supporting reliable signal transmission over longer runs.
