Stocked cable types and when to use them

We focus stock on the cable types that solve 90% of South African IoT projects: multi-core sensor cable for short runs, twisted-pair for differential signalling, USB and micro-USB for development boards, and shielded coax for antennas. Below is a compact spec table to compare common choices at a glance.

If you need to confirm stock at a specific branch before heading in, check our branches and trading hours page: Branch locations & hours. Mention the required part number and we’ll hold it for collection where possible.

Specification callouts you should verify before buying

• Conductor cross-section (mm2) - affects voltage drop on longer runs
• Shielding and drain wire - essential for noisy environments or long antenna feeds
• Jacket material - UV vs indoor rated for external deployments
• Connector gender and pinout - avoid field rework by confirming before buying

Simple calculation: voltage drop for long sensor runs

Use Ohm’s law to estimate conductor size. Formula: Vdrop = I * R; where R = resistivity * length / area. For quick sizing use lookup: 0.5 A over 20 m round-trip with 0.22 mm2 conductor yields ~2.5 V drop - unacceptable for a 5 V sensor bus. Choose 0.75 mm2 or use local powered repeaters.

Troubleshooting common installation problems

• Noisy readings: swap to shielded twisted-pair and ground the drain conductor
• Intermittent USB power: use a cable rated for higher current and shorter length
• Connector fit issues: confirm pinout and use a bench multimeter before soldering

Why this matters for South African projects

Local stock reduces calendar risk: university labs, maker spaces and small integrators can still source components when global shipping windows stretch. We stock brands and product families that recur in SA projects so replacements and expansions are straightforward. If timing is critical, choose components noted as in-branch and bundle accessories in one order to avoid multiple wait cycles.

Summary: pick cables by electrical needs and installation environment, add the right terminals and strain relief, verify connector pinouts, and use local stock to keep your project on schedule.
