Buy 4-core 0.34mm2 sensor cables at competitive prices from Communica. Ideal for wiring sensors, automation, and instrumentation. SA branches, VAT quotes & local support.
Reliable 4-core 0.34mm2 sensor cables at accessible prices for projects and installations.
Order online or collect from Samrand, Pretoria, or Cape Town branches for quick deployment.
Suitable for sensors, automation, instrumentation, and prototyping in education and industry.
4-core 0.34mm2 sensor cables are a widely used solution for wiring industrial sensors, field devices, and control circuits. Their compact size, flexibility, and reliability make them an excellent fit for student projects, maker prototypes, and demanding industrial equipment.
Communica maintains deep stock of signal and sensor cables to suit South African electrical environments. Select from trusted global and maker brands, available for online order or branch collection, with VAT invoicing for business and educational procurement. All core ranges are suitable for:
4-core 0.34mm2 sensor cables are designed for low-voltage, low-current signals. Here's how they typically compare:
| Attribute | Spec/Range |
|---|---|
| Cores | 4x (individual colour coded) |
| Conductor Area | 0.34mm2 (approx. 22 AWG) |
| Insulation | PVC or PUR (check for abrasion tolerance) |
| Voltage Rating | Typically 300V max |
| Temperature Range | -20 degreesC to +80 degreesC (PVC) |
| Jacket Colour | Grey, black, or yellow (varies by batch/brand) |
Options may include overall shielding (foil/drain wire) for improved noise resistance in automation or process settings.
Start by matching the voltage and current ratings required for your sensors. Most industrial sensors draw minimal current (10-50 mA), so 0.34mm2 copper is amply rated for runs under 50 m. Where noise immunity is critical, opt for a shielded cable.
Suppose you're wiring four limit switches in a small automated conveyor:
Voltage drop formula:
Vdrop = I x R x Length
For 0.34mm2 copper, resistance ~ 56 /km. For a 22 m run (0.022 km):
This fall is negligible for most sensors and devices at these lengths and currents, confirming 0.34mm2 is a safe, cost-effective choice.
