Introduction to the SFX OSP1-60 LSZH 1‑Pair Shielded Cable
The SFX OSP1-60 LSZH is a compact, professionally specified 1‑pair instrumentation cable supplied on a 100 m reel. With 18 AWG conductor construction (16 x 0.30 mm tinned copper), an overall Al‑PET foil screen and a tinned copper drain, plus a low‑smoke zero‑halogen (LSZH) outer jacket, this cable is designed for audio, control, instrumentation and panel wiring where good electromagnetic interference (EMI) protection and reduced fire emissions are important. Rated to 600 V and specified for operation from -40°C to +70°C, it is a versatile choice for contractors, system integrators and technically minded DIYers working in commercial and public environments.

Detailed specifications and benefits
The cable uses 16 strands of 0.30 mm tinned copper to form an 18 AWG conductor. Stranded tinned copper combines flexibility with corrosion resistance, which is especially valuable in long cable runs and installations where frequent handling or movement may occur during installation. HDPE insulation provides a stable dielectric with an insulation thickness of 0.45 mm, offering good mechanical robustness and consistent electrical characteristics across the rated temperature range.
Shielding is a critical factor for instrumentation and audio cables. The SFX OSP1-60 LSZH uses an overall Al‑PET foil wrap with a tinned copper drain conductor. This construction provides >115% foil coverage (effective overlap) and a low‑impedance path to ground via the drain wire. The result is reliable protection against electromagnetic interference (EMI) and radio‑frequency interference (RFI), which helps preserve signal integrity over modest distances and in electrically noisy environments such as equipment racks, machine rooms, or near power wiring.
The grey LSZH jacket (RAL 7042) is a defining safety feature. In the event of a fire, LSZH materials emit significantly less smoke and virtually no halogenated toxic gases compared with standard PVC jacketing. This makes the cable suitable for use in enclosed public spaces, theatres, transport hubs, data centres and other locations where occupant safety and reduced corrosive combustion products are priorities.
With a rated voltage of 600 V and an operating range from -40°C to +70°C, the cable suits many indoor and protected outdoor applications. Insulation resistance >200 MΩ/km @ 20°C and maximum DC resistance <25 Ω/km @ 20°C (per datasheet) ensure predictable, low‑loss behaviour — important for low‑voltage control and audio signals. The compact overall diameter (~5.50 mm) helps when routing multiple runs in trays or panels and reduces connector/junction box space requirements.
Use cases and scenarios where the SFX OSP1-60 LSZH excels
- Audio signal runs in installed sound systems:The cable’s shielding and low capacitance construction make it a good choice for balanced audio or low‑level microphone lines where EMI rejection is required.
- Instrumentation and control wiring:For PLC inputs/outputs, sensor connections and control circuits inside panels, the cable provides a compact, screened option that simplifies routing and grounding arrangements.
- Public buildings and enclosed spaces:LSZH jacket reduces smoke and toxic gas emission — a major advantage for schools, hospitals, transport hubs and theatres where occupant safety and firefighting considerations are critical.
- Machine rooms and data centres:Where space is at a premium and EMI can affect equipment, a compact screened pair helps maintain signal fidelity without occupying excessive tray space.
- Contractor installations and retrofit projects:Supplied on a 100 m reel and with a compact diameter, the cable is convenient for installers who need manageable lengths and easy storage.
Comparisons with similar products on the market
When evaluating instrumentation and audio cables, buyers typically compare conductor gauge, shielding type, jacket material and overall diameter. The SFX OSP1-60 LSZH sits in a competitive niche with these notable differentiators:
- VS PVC‑jacketed screened cables:Standard PVC‑jacketed cables may be less expensive but do not offer the low smoke/low halogen benefits. In environments where occupant safety or equipment corrosion from combustion by‑products is a concern, LSZH is clearly preferable.
- VS pair‑by‑pair screened multicore cable:Multicore cables that provide individual pair screening can deliver superior crosstalk rejection between pairs but are thicker and less flexible. For single pair audio or control runs where crosstalk between pairs is not an issue, an overall screened 1‑pair cable like SFX OSP1-60 LSZH is more compact and often simpler to terminate.
- VS heavier gauge or silver‑plated conductors:Some premium cables use larger conductors or silver plating for marginally better conductivity. However, 18 AWG tinned copper is a pragmatic and cost‑effective choice for most instrumentation and audio applications, balancing flexibility, resistance and cost.
- VS braided shield constructions:Braided copper shields can offer lower DC resistance to ground and better mechanical robustness, but foil + drain constructions typically provide excellent high‑frequency coverage and are very slim. The SFX uses Al‑PET foil for close wrap and a drain for grounding—ideal for compact routing and high‑frequency EMI protection.
Typical customer feedback and observed pros/cons
There are no public customer testimonials included with the product data provided here. However, based on the product’s specification and typical field use, common user impressions are likely to include:
- Positive:Users appreciate the compact diameter for tight cable management, effective EMI rejection from the overall foil shield, and the safety benefits of LSZH jacketing in public or enclosed spaces.
- Positive:Flexibility and ease of termination due to fine stranded tinned copper conductors and a convenient drain wire for shielding termination are frequently highlighted by installers.
- Considerations:For specialized high‑performance audio or very long balanced lines, some professionals may prefer pair‑by‑pair shielding or larger conductor sizes; for those applications it’s worth comparing specification sheets and measurement data.
Practical tips for installation and use
To get the best performance from the SFX OSP1-60 LSZH:
- Terminate the drain wire and foil properly to a single point earth at the equipment end to avoid ground loops.
- Avoid routing the cable parallel and close to mains power cables; where crossing is necessary do so at right angles to reduce induced interference.
- Observe the rated temperature range and protect the jacket from sharp edges or repeated mechanical abrasion during installation.
- Follow local wiring regulations and, where required, have a qualified person perform terminations and testing.
Pricing and procurement notes
The product is supplied on a 100 m reel (SKU: SFX/OSP1-60-LSZH-GRY-100, EAN/GTIN: 5056631505754). A suggested retail price has been set to position the cable competitively while maintaining margin; please confirm the currency and VAT preference to produce definitive RRP recommendations. As an example, if a supplied cost price of 60.29 is in the same currency, a suggested price of 74.99 yields a gross margin of about 19.6% (cost / (1 - margin) = minimum price for 16% margin → 60.29 / 0.84 = 71.79). Exact pricing should factor in shipping, duty, stockholding and local market conditions.
Conclusion: why choose the SFX OSP1-60 LSZH
