Shielded multi-pair serial communication cables, including the 9841 and 3105A families.
Belden's serial data cables are low-capacitance twisted-pair cables for RS-485, RS-422 and RS-232 links such as Modbus RTU, BACnet MS/TP, DMX512 and PLC programming ports. They use tinned copper conductors in 22 or 24 AWG, polyethylene or foam insulation, Beldfoil shields with a braid or drain wire, and PVC jackets rated CM or PLTC. The 120 ohm RS-485 types keep reflections low on long multidrop lines.
9841 is the single-pair 24 AWG RS-485 cable and 9842 its two-pair version; LSZH variants 9841LW and 9841LV exist. 3105A is the heavier 22 AWG single pair with braid for industrial tray runs, 3106A adds a separately shielded conductor for a signal common, and 3107A has two pairs. 9729 is a two-pair 24 AWG 100 ohm cable with individually foiled pairs for RS-422. 8723 is the classic two-pair 22 AWG individually shielded cable for RS-232 and instrument signals.
Indian integrators use these between PLCs, energy meters, VFDs, BMS controllers and SCADA RTUs. Choose by interface and impedance, number of pairs (one for half-duplex RS-485, two for full-duplex RS-422), gauge for distance, shield type for the noise environment and jacket rating for cabinet, tray or plenum routing.

Bulk and project quantities welcome; delivery across India. See the whole Belden range we quote on the Belden page, or the full catalogue on Belden's own site.
The series asked for most. Any other Belden part number is quoted the same way.
Yes. 9841 is a 120 ohm RS-485 cable, which matches Modbus RTU, BACnet MS/TP and most two-wire multidrop networks. Use 9842 if the link is four-wire or two separate buses share one route.
For long industrial runs, cable tray installation or where mechanical robustness matters, 3105A and 3107A in 22 AWG give lower resistance and a stronger braid. For cabinet and short building runs, 24 AWG 9841 is adequate.
Yes. 9841LW and 9841LV are the low-smoke zero-halogen versions of 9841 and are listed for Modbus RTU, CANopen, BACnet MS/TP and DMX512 use. Elume quotes them on order with a GST invoice.
