Introduction: What the SFX/OSP6-LSZH-D-GRY-100 is and its key features
SFX/OSP6-LSZH-D-GRY-100 — 6‑pair 24 AWG Screened LSZH Cable (100 m)is a compact, 6‑pair control and data cable supplied on a 100 m reel. It combines 24 AWG tinned stranded copper conductors with an overall foil screen and a drain conductor, enclosed in an LSZH (Low Smoke Zero Halogen) jacket in grey (RAL 7042). Designed for indoor signal, control and low‑voltage power use, this cable delivers reliable electrical performance while minimizing smoke and toxic emissions in the event of fire.
Key features at a glance:
- Six pairs (6 core) of 24 AWG tinned stranded copper conductors — compact for tight installations.
- Overall foil screen with drain conductor for EMI/RFI protection.
- LSZH individual insulation and overall jacket — safer for public and enclosed spaces.
- Rated to 600 V and operates from −40 °C to +70 °C.
- Supplied on a 100 m reel for easy handling and installation.
Detailed specifications and benefits
The technical build and measured parameters of the SFX/OSP6-LSZH-D-GRY-100 are tailored for control, signalling and low‑voltage distribution tasks. Below are the important specifications and the practical benefits each provides:
- Conductor:Tinned stranded copper (24 AWG, ~0.20 mm²). Tinning provides improved corrosion resistance and reliable long‑term connectivity in environments where moisture or oxidation can be a concern.
- Cores / pairs:6 pairs (6 core) with colour coded pairs (Red/Black; White/Black; Green/Black; Blue/Black; Yellow/Black; Brown/Black). Colour coding speeds installation and reduces termination errors.
- Overall screen:Foil shield with drain conductor. This provides effective protection from EMI/RFI for signal integrity in electrically noisy environments such as near motor drives, switching power supplies or radio equipment.
- Insulation & jacket:LSZH on individual pair insulation and overall jacket (grey RAL 7042). LSZH reduces the production of smoke and hazardous halogenated gases if a fire occurs, making it safer in confined public environments.
- Electrical & mechanical:Rated voltage 600 V; insulation resistance >200 MΩ/km @ 20 °C; max DC resistance <79 Ω/km @ 20 °C. Operating temperature range is broad (−40 °C to +70 °C), covering most indoor and lightly exposed scenarios.
- Physical size:Compact overall diameter ~7.20 mm, jacket thickness ~0.70 mm — suitable for conduit runs or cable trays where space is limited.
- Compliance:CPR / Fire rating Dca (see datasheet). Check the official datasheet and supplier for UKCA/CE declarations and ensure installations follow local wiring regulations.
For installers and system designers, the combination of tinned stranded conductors and overall screening means dependable connection quality and improved immunity to interference without the bulk of larger gauge cables. The LSZH construction provides important safety advantages for buildings with public access, enclosed plant rooms, transport hubs and other places where reduced smoke and toxic emissions are critical. The 100 m reel format is convenient for on‑site deployment and avoids frequent joins.
Use cases and scenarios where this cable excels
This product is optimised for control, signalling and low‑voltage power applications where screening and low smoke characteristics are required. Typical and high‑value use cases include:
- Access control and security systems:Reliable signal transmission for keypads, card readers, door controllers and CCTV that must operate near other electrical equipment without interference issues.
- Building automation & sensors:Connecting temperature sensors, environmental monitors and building management controllers where signal fidelity is needed over runs inside commercial buildings.
- LED and lighting control:Suitable for low‑voltage LED control lines and DMX/lighting control installations where consistent signal integrity is essential.
- RS‑232/serial links and control wiring:Ideal for serial communications and control circuits in panels and machinery where an overall screen protects against external noise sources.
- Transport and public spaces:LSZH jacket reduces risk in tunnels, stations, airports, theatres and similar spaces where occupant safety and reduced toxic emissions are priorities.
- Compact installations:The small overall diameter makes this cable easy to route through conduits, trunking and cramped cabinet interiors.
Comparisons with similar products in the market
When selecting cable for control and data tasks, it's useful to compare SFX/OSP6-LSZH-D-GRY-100 with other common options:
- VS Unscreened multiconductor cable:Unscreened cables are cheaper but more vulnerable to EMI/RFI. Where interference or variable signal quality could be an issue, the screened SFX/OSP6 provides superior performance and greater reliability.
- VS PVC jacketed cable:PVC jackets are economical but release dense smoke and corrosive halogens when burned. For installations in public or enclosed spaces, LSZH is a safer choice and increasingly preferred to meet building safety standards.
- VS individually shielded pairs:Cables with individual pair shields reduce pair‑to‑pair crosstalk for more demanding data applications. The SFX/OSP6 uses an overall foil screen which offers excellent external noise rejection and is often sufficient for control, serial links and most sensor networks. For high‑speed differential signalling where pair isolation is critical, consider a cable with individually shielded pairs.
- VS braided/shielded alternatives:Braided shields deliver superior mechanical robustness and better low‑frequency shielding than foil but are typically bulkier and more expensive. The foil + drain arrangement in SFX/OSP6 is a pragmatic balance of good shielding, compact size and cost effectiveness.
Customer feedback and typical reviews
While individual experiences vary by installation, installers and systems integrators commonly highlight the following points when using this type of cable:
- "The LSZH jacket was essential for a public‑building install — peace of mind for safety and compliance."
- "The overall foil screen noticeably reduced noise on serial lines running near drives and transformers."
- "Compact diameter made routing through our existing trunking straightforward — saved time on the job."
These representative comments reflect the practical benefits many users report: safety in public spaces, improved signal integrity in electrically noisy environments and easier installation due to compact construction and clear pair colour coding.
