LumaGrove Screened Pure Copper Core Cable, 4 Core 0.75mm² Shielded
Core and insulation: The cable uses a pure copper core with a 0.75mm² cross-section, paired with elastic PVC insulation for durability. It is designed for high-conductivity applications where stable signal transmission matters. The conductor is 99.99% high-purity oxygen-free copper, which reduces resistance and improves overall performance in data and control networks.
Shielding: The product features double shielding—tinned copper braided mesh and aluminum foil—providing strong protection against electromagnetic interference (EMI). This makes it suitable for environments with potential cross-talk and external noise, such as industrial settings or proximity to motor drives.
Construction and use: An extrusion process is used in production, ensuring consistent geometry and reliable performance across lengths. This 4-core configuration is appropriate for RS485 and similar differential signaling systems, enabling robust multi-wire connections with relatively long runs.
LumaGrove Screened Pure Copper Core Cable, RVSP 4-Core 485 Cable 5 Meters
Core and insulation: This model uses a pure copper core designed for 485 communication channels. The twisted-pair configuration improves noise rejection and signal integrity over moderate distances. AWG compatibility ranges from 24 AWG to 16 AWG, with the 4-core option listed among commonly used sizes for 4-conductor runs.
Shielding and construction: The cable uses shielded twisted-pair construction with a focus on stability in RS485-style networks. The shielding helps mitigate EMI and external noise, protecting the integrity of data transmission in industrial or lab environments.
LumaGrove Cat5e Four Shielded Cable
Core and insulation: This Cat5e option uses pure oxygen-free copper conductors with a 0.4mm inner diameter, offered in lengths of 5, 10, and 30 meters to accommodate both short- and long-run installations. The 4-core configuration supports standard Ethernet-like or control wiring requirements when shielding is advantageous.
Shielding: The aluminum shield provides an extra barrier against EMI. This makes the cable suitable for environments with notable electrical noise, helping preserve data integrity for networking and sensor applications.
LumaGrove Twisted Pair Shielded Wire, 1M, 4 Core 20AWG
Conductor and gauge: This product features a 20 AWG (0.5mm) cross-section, which is appropriate for RS485 and other control networks. The 4-core twisted-pair conductors are designed to maintain signal integrity over moderate distances, with shielding that reduces EMI impact.
Shielding and flexibility: Premium shielded construction emphasizes EMI resistance and durable performance in potentially noisy environments. The 1-meter length makes it suitable for short-distance interconnects, breakout wiring, or modular assemblies where space is limited.
LumaGrove Screened Pure Copper Core Cable, 1M RVSP Multicolor Shielded
Core and insulation: The 1-meter RVSP cable features a multicolor shielded twisted pair design suitable for 485 communication lines. It supports 2-16 cores in various core counts and gauges, with a focus on 4-core configurations for compact systems.
Shielding and versatility: The shielded design helps minimize EMI, while the multicolor jacket aids in color-coding and easy identification in complex installations. The product supports multiple cross-section options, making it flexible for different 4-core wiring scenarios.
LumaGrove Screened Pure Copper Core Cable, 4 Core 24AWG 0.2mm
Core and insulator: This variant uses 24 AWG conductors with a 0.2mm cross-section in a 4-core arrangement. It is designed for lightweight, compact wiring needs with reliable signal integrity for 485-style communications and control wiring.
Shielding and insulation: Shielding protects against EMI while a rugged PVC jacket adds mechanical protection. It is well-suited for doorbell lines, intercom, and other 485-based networks that require stable performance in smaller form factors.
Buying Guide: Key Purchase Considerations for 4-Core Screened Cables
- Conductor material and purity: Look for pure copper or OFC (oxygen-free copper) for low resistance and consistent signal quality, especially in RS485 and data transmission.
- Shielding effectiveness: Double shielding (foil plus braided shield) or high-quality single shielding reduces EMI and cross-talk, essential in industrial or noisy environments.
- Conductor gauge and core count: For 4-core systems, evaluate whether 0.2mm², 0.5mm², or 0.75mm² cross-sections match your current requirements and distance expectations.
- Jacket and insulation: PVC or equivalent insulation should balance flexibility and durability; consider ambient temperature and exposure conditions when selecting jackets.
- Length options: Choose cable lengths that minimize the need for splices and maintain signal integrity; modular systems benefit from standardized lengths (e.g., 1m, 5m, 10m).
- Applications: RS485, doorbell/intercom, and general control wiring each have different noise tolerance and shield needs; ensure the chosen cable aligns with the intended use.
- Installation environment: Industrial floors, laboratories, and residential environments each pose unique EMI challenges; shielding and jacket ratings should reflect these conditions.
- Cost vs. performance: Higher shield density and pure copper cores typically deliver better reliability but at a higher cost; balance with project requirements and budget.
In summary, 4-core screened cables offer robust performance for data and control wiring in various settings. When selecting a cable, prioritize conductor purity, shielding quality, and appropriate gauge to ensure reliable operation across your specific use case.
