LSZH gray jacket offers low-smoke, halogen-free safety for indoor installations.

## Long description

FOTUX ® BELDEN 9841 S/FTP for RS-485 data transmission, dual shielded, LSZH gray is a communication cable designed for reliable serial data links in industrial and building automation environments. The construction features individually foil‑shielded pairs combined with an overall braided shield, which reduces electromagnetic interference and crosstalk. The gray low‑smoke, zero‑halogen (LSZH) outer jacket is intended for indoor installations where reduced smoke and no halogen emissions are required.
Advantages
The S/FTP design delivers enhanced noise immunity by providing both pair-level foil shields and a full braid, improving signal integrity for RS-485 networks. The cable supports stable differential signaling over moderate distances and is suitable where robust shielding is needed against electrical noise from motors, drives, and other equipment. The LSZH jacket increases safety in enclosed spaces by minimizing toxic fumes and corrosive gases in the event of a fire. Its gray outer sheath offers a neutral appearance for visible routing in cabinets and conduits.
Suitable for (tasks / use cases)
RS-485 serial communication links for industrial controllers and field devices
Building automation and HVAC control networks
Data transmission in electrical rooms, control panels, and machine enclosures
Indoor installations requiring low‑smoke, halogen‑free cabling
Key specifications
Conductor arrangement: twisted pairs with individual foil shields
Overall shielding: braided shield over all pairs
Jacket material: low‑smoke, zero‑halogen (LSZH)
Outer color: gray
Designed application: differential serial data transmission (RS‑485)
Typical benefits: reduced EMI/RFI susceptibility, lower crosstalk
How to use
Route the cable following standard installation practices for communication wiring: avoid running alongside high‑power mains cables and maintain recommended separation from noise sources. Terminate the shield(s) appropriately at equipment end points to preserve the intended grounding and shielding performance; typically the braided shield and pair foils are connected to earth at a single point per segment. Use correct RS‑485 termination resistors and biasing as required by the network topology. For indoor installations, secure the cable in trays, conduits, or ducts suitable for LSZH materials and observe bend radius limits during installation.
Usage recommendations
For optimal RS‑485 performance, use the cable for balanced differential pairs only, apply single‑point grounding of shields where recommended by system designers, and verify network termination and biasing. Inspect the LSZH jacket condition before and after installation and avoid exposure to direct sunlight or aggressive chemicals to preserve material properties.
