28AWG 20-Core Shielded Data Cable

A single intermittent signal fault can idle a robotic cell for hours. Tracking down noise-induced errors in a dense cable tray costs more in engineering time than the cable itself ever will. The 28AWG 20-Core Shielded Data Cable is built specifically for these high-density, low-voltage control and data circuits where cross-talk and EMI are daily risks. It brings 20 conductors into one shielded jacket, slashing installation bulk and termination time while keeping signal paths clean. This is commodity components engineered for long-term electrical repeatability, not discrete wiring improvisation.

High-Density Conductors: 20 Cores in One Jacket

Feature: 20 individually insulated 28 AWG conductors laid up under a unified shield.
Advantage: Single-cable pull instead of bundling multiple twisted pairs or separate leads.
Benefit: Shrinks cable tray fill, reduces labeling errors, and speeds up panel-to-field terminations on multi-channel sensor or actuator loops.

Dedicated Overall Shield

Feature: A continuous aluminum-foil shield with a tinned-copper drain wire.
Advantage: Provides 100% optical coverage against radiated EMI, with a drain wire that simplifies fast grounding.
Benefit: Prevents false triggering of logic inputs, erratic analog readings, or corrupted low-speed digital streams in plants with VFDs, motor starters, or nearby RF sources.

Mechanical Flexibility without Signal Degradation

Feature: Stranded 28 AWG conductors with a semi-rigid PVC insulation and a flexible matte PVC jacket.
Advantage: Maintains twist stability and consistent center-to-center spacing even under repeated flexing or routing through narrow cable chains.
Benefit: Supports moving machine axes and tight panel door hinges without kinking the shield or opening micro gaps that invite intermittent noise.

Clean Multipoint Termination

Feature: Color-coded, sequentially numbered cores available in standardized alpha-numeric schemes.
Advantage: Removes the guesswork during stripping and landing—each core is immediately identifiable at both ends.
Benefit: Cuts commissioning time significantly. A technician lands all 20 conductors against a terminal block in one pass, verifying only against the core print, not an erratic continuity tone.

Industry Applications & Scenario Validation

• Industrial Automation & PLC I/O
  Connecting a bank of proximity sensors or solenoid valves to a central PLC rack. The 20-core structure maps directly to a 20-channel input card, eliminating 19 extra cable runs and untangling the wiring duct.

• Motion Control & Linear Encoder Feedback
  Routing incremental encoder signals (A, B, Z channels plus power) from multiple axes back to the motion controller. The shield blocks common-mode noise from spindle drives that otherwise overwhelms weak 5 V differential pulses.

• Building Management & HVAC Sensor Networks
  Pulling multiple temperature, CO₂, and humidity sensor circuits along a single ceiling tray. The cable remains flexible enough to dress into sensor heads while its jacket resists the degradation common in plenum-like unconditioned spaces.

• Test & Measurement Data Acquisition
  Linking a distribution panel of thermocouple amplifiers or strain-gauge bridge completions to a DAQ chassis. The low DC resistance of the drain wire maintains a single-point ground reference across all channels, suppressing ground-loop hum.

• Communication & Low-Speed Bus Systems
  Transporting RS-485 multi-drop or CAN bus physical layers across a factory floor. Twenty cores allow dedicated power, data A/B pairs, and spare service connections inside one armor-like shield, keeping bus arbitration clean.

• ✅ Shield coverage and drain resistance verified by optical microscopy and milliohm meter
• ✅ RoHS 3 (2011/65/EU + amendments) and REACH SVHC compliant – independent third-party test reports for restricted substances
• ✅ Full form, fit, and function testing under an ISO 9001:2015 audited quality plan

FAQ

Does the 20-core configuration support splitting the cable into separate twisted pairs for RS-422/485?
The cores are laid parallel, not paired and twisted individually. However, for short runs at baud rates below 1 Mbit/s, many engineers assign adjacent cores as data pairs and rely on the overall foil shield to suppress common-mode interference. If your application runs above 500 kbit/s or over distances greater than 15 metres, we recommend dedicated twisted-pair constructions. We can provide a 10-pair 28 AWG variant on an OEM basis.

What minimum order quantity applies, and can you supply cut-to-length segments?
Standard factory spools are 305 m (1,000 ft) per reel. We also stock 100 m and 50 m pre-cut lengths for prototype and low-volume panel builds. Lead time for stock lengths is 2–3 working days. Full-reel orders ship within 5 working days. For custom jacket colours, printed legends, or non-standard put-ups, the MOQ is typically 3,000 m with a separate lead time confirmation.

How do I determine if the 30 V voltage rating is sufficient for my 24 V DC control circuit?
The 30 V rating applies to the peak operating voltage, not just the nominal system level. In a 24 V DC circuit with tight regulation, there is no derating concern. Where the circuit includes high inductive spikes from relay coils or solenoid valves, we advise verifying that transients do not exceed 30 V between any conductor and the drain or between adjacent conductors. For additional safety margin, we offer a 300 V-rated 22 AWG version with the same 20-core count.
