ISP2 2-Pair Individually Foil-Screened Instrumentation Cable, 22 AWG, PE Jacket, 200m Reel ITM004538

Introduction: ISP2 2‑Pair Individually Foil‑Screened Instrumentation Cable and its key features

ISP2 2‑Pair Individually Foil‑Screened Instrumentation Cable — 200 m reel is a purpose‑built installation cable designed for low‑voltage data and instrumentation applications where signal integrity matters. With two individually foil‑screened pairs, 22 AWG tinned copper conductors and a UV‑resistant polyethylene (PE) jacket, this 200 m reel balances electrical performance, ease of installation and outdoor durability. Its rated voltage of 600 V and temperature range from −20 °C to +80 °C make it suitable for many CCTV, telemetry and instrumentation runs, while features such as an integral drain conductor and nylon rip‑cord simplify termination and installation.

Detailed description of specifications and benefits

The ISP2 cable is engineered with a set of specifications that target noise reduction, mechanical robustness and practical handling on site. Key technical points include:

• Conductor construction:22 AWG tinned copper stranded conductors (7×0.24 mm strands, ~0.33 mm²). Tinning aids corrosion resistance and solderability, while the flexible strand construction eases routing in confined spaces.
• Individual pair screening:Each pair is wrapped in its own foil screen and includes a drain conductor for effective grounding and simple termination. Individual screening significantly reduces inter‑pair crosstalk and helps preserve signal integrity in noisy environments.
• Insulation and jacket:SR‑PVC insulation (0.24 mm) and a PE outer jacket (0.45 mm) provide a reliable dielectric and a UV‑resistant exterior (black RAL 9005) suitable for above‑ground exposure and in‑duct runs.
• Electrical and environmental ratings:Rated voltage 600 V, operating temperature −20 °C to +80 °C, insulation resistance >200 MΩ/km @ 20 °C and maximum conductor DC resistance <50 Ω/km @ 20 °C. The cable carries a CPR classification of Fca.
• Mechanical details:Overall diameter approx. 4.10 ±0.20 mm, strand diameter 0.64 mm and a 210D nylon rip‑cord for fast jacket removal—helpful during field terminations on a 200 m reel.

Benefits arising from these specifications:

• Improved signal quality:Individual foil screening for each pair reduces electromagnetic interference (EMI) and inter‑pair crosstalk—critical where low‑level analogue signals or digital telemetry must be preserved.
• Reliable outdoor performance:The PE jacket is UV‑resistant and suitable for exposed runs. For long or exposed installations, standard mechanical protection (conduit or containment) is recommended.
• Easy termination:The included drain conductors permit straightforward connection to earth/shield at termination points, saving installer time and reducing the chance of improper shielding connections.
• Cost‑effective and practical length:A 200 m reel offers a convenient balance between coverage for site runs and manageable reel size for storage and transport.

Use cases and scenarios where ISP2 excels

The ISP2 2‑pair screened cable is a versatile choice for many low‑voltage installations. Typical and recommended use cases include:

• CCTV and security systems:Ideal for camera runs where interference from nearby power cables, lighting or other data lines could degrade video quality. Individual pair screening helps maintain clean signals to cameras and encoders.
• Instrumentation and telemetry:Suited for sensor wiring, telemetry links and remote monitoring lines where low‑level analogue or digital signals must be protected from external noise sources.
• Access control and low‑voltage data links:Reliable for card reader data lines, door contact sensors and other access control wiring that benefit from screened pairs to reduce errors and false triggers.
• Building automation and sensors:Where controllers and sensors are sited near motors, HVAC equipment or fluorescent lighting, the screened construction helps prevent interference and maintains system stability.
• Retrofit and new installations:The 22 AWG conductor presents a good compromise between current‑handling and flexibility, making the cable suitable for both retrofit projects and new builds in commercial or light industrial environments.

Installation notes: install per local wiring regulations and manufacturer guidance. Use appropriate terminations and consider conduit or mechanical protection for exposed outdoor runs. For mission‑critical systems, have terminations performed by a qualified technician to ensure proper shield bonding and reliable connections.

Comparisons with similar products on the market

Understanding how ISP2 compares to alternative cabling helps select the right product for each job. Below are common comparisons:

• Individually screened vs overall screened cables:Cables with an overall screen provide a single shield around all pairs but do not prevent inter‑pair crosstalk as effectively as individually screened pairs. ISP2’s per‑pair foil is preferable where multiple sensitive signals run close together.
• Screened vs unshielded cables:Unshielded cables (e.g., standard UTP or simple twin) can be sufficient for low‑noise environments, but in installations near power or motor loads, screened pairs like ISP2 yield superior performance and fewer communication errors.
• Conductor gauge comparison:22 AWG is a common choice for instrumentation and CCTV balances flexibility and current capacity. Larger conductors (18 AWG or 16 AWG) carry more current and may be used where power delivery is a concern, but they are thicker and less flexible. For data and low‑power sensors, 22 AWG is typically optimal.
• Jacket materials and durability:PE jackets offer better UV resistance and outdoor durability than basic PVC jackets. For direct burial, specially designed burial cables are recommended; ISP2 is well suited to above‑ground or in‑duct applications and benefits from conduit protection where mechanical abuse is possible.
• Price and value:It competes well with alternatives that compromise shielding quality or outdoor resilience to reduce cost.

Conclusion: Why ISP2 is a great choice

The ISP2 2‑Pair Individually Foil‑Screened Instrumentation Cable (200 m reel) is a practical, well‑specified solution for installations demanding preserved signal quality and outdoor durability. Its combination of individually screened pairs, tinned stranded 22 AWG conductors, PE UV‑resistant jacket and convenient 200 m reel length makes it particularly well suited to CCTV, instrumentation, telemetry and access control systems.

Whether you are an installer seeking a reliable cable that simplifies terminations and reduces field failures, or a system designer specifying wiring for a new build, ISP2 offers a solid balance of electrical performance and value.

For best results, install ISP2 in accordance with local codes, use suitable mechanical protection for exposed runs, and ensure proper shield termination to maximise the cable’s benefits for critical systems.
