Why choose Communica for D-sub connectors
Communica stocks a broad selection of D-sub connectors, shells and cable assemblies so you can finish projects on time. We focus on availability, clear specs and practical compatibility notes that matter to South African makers, labs and technicians - not just broad product lists. Order for branch collection or delivery from our Samrand warehouse to avoid long lead times and get VAT invoices for institutional procurement.
Local availability and purchasing flexibility
Many projects fail on procurement delays. We maintain local stock for common D-sub shell sizes (9, 15, 25, 37, 50-pin) and typical shell types (male, female, right-angle, PCB-mount). Check stock in Samrand or any branch before you commit: branches & trading hours makes collection straightforward.
Specification callouts that matter
When selecting a D-sub, three specs decide success: shell size and pin count, mounting style, and contact termination. We highlight these on product pages so you can rapidly compare options and avoid backwards trips to the bench.
- Shell/pin: Choose 9/15/25/37/50 by required signals or connector standard.
- Mounting: PCB-mount, cable hood, right-angle for cramped enclosures.
- Termination: Solder cup, crimp, IDC or through-hole - pick based on cable skill and production volume.
Quick compatibility guide
D-sub connectors are physically keyed by shell size; however, pay attention to contact types and gender. For example, a 25-pin male PCB mount won’t mate with a 25-pin cable hood that uses solder-cup contacts. If you need help matching parts, see our product collections for visual cues and part groupings: d-sub-connectors-in-stock.
Specification comparison table
Use this quick table to narrow choices before viewing specific parts.
| Feature | Common Options | When to choose |
|---|---|---|
| Shell size | 9, 15, 25, 37, 50 | Signals count, legacy serial (9/25), VGA (15), custom I/O (25+) |
| Termination | Solder-cup, crimp, IDC, through-hole | Solder-cup for hand wiring, IDC for quick assembly, crimp for reliability |
| Mounting | Panel, PCB, cable hood | Panel for front panels, PCB for board-level, cable hood for assemblies |
