If you're building or repairing computers, servers or embedded systems in South Africa you need reliable local access to the right connectors - SATA, USB, RJ45, HDMI, board headers and power plugs - without long import delays. Communica combines national inventory, branch pickup and technical selection support so you can finish projects on schedule and get VAT-compliant invoices for education, prototyping or procurement teams.
Our ranges cover common computer connector categories: USB (A/C/Cable), HDMI, DisplayPort, RJ45 Ethernet jacks, SATA/SAS, internal board headers (PCIe, M.2, FFC/FPC), power jacks and power cables, plus cable assemblies and accessories. This selection supports makers, university labs, technicians repairing desktops/servers, and engineering procurement looking for spec alignment and quick collection.
When choosing a connector, consider pitch, current rating, mating cycles, keyed orientation and board footprint. Below is a compact spec comparison to help you shortlist parts quickly.

Match shrouding and orientation |
- Confirm electrical: max current and voltage per pin for power connectors.
- Check mechanical: board footprint and mating orientation against your PCB design.
- Count cycles: choose higher mating-cycle parts for frequent connect/disconnect.
- Decide on shielding or locking features for robust installations.

For simple internal power to SATA drive using a Molex-to-SATA cable:
Molex (4-pin) -----[Cable]----- SATA power (15-pin)
Pin mapping: 12V (yellow), 5V (red), GND (black)
For board-to-board header examples (2.54mm 4-pin):
Header: 1 2 3 4
Signal: VCC GND TX RX
Always verify pinouts from your device schematic before soldering.
