The keyword "iot-cables-hkd-ribbon-jumper-male-male-15cm-40way" refers to a flat HKD-style ribbon jumper assembly: 40 conductors, 2.54mm (0.1") pitch, male pins on both ends, 150mm length. These cables are commonly used to connect IDC headers, sensor shields, breakout boards and GPIO headers on microcontroller and single-board computer projects.
Below are the typical specs you should check when buying 40-way 15cm male-male ribbon jumper cables for IoT and prototyping work. Use the keyword when searching product pages or filtering results on Communica's site to find matching stock quickly.
| Spec | Typical Value | Why it matters |
|---|---|---|
| Conductor count | 40 | Matches 40-pin headers on many boards (e.g., GPIO on some SBCs). |
| Pitch | 2.54 mm (0.1") | Standard spacing for breadboards and through-hole headers. |
| Length | 150 mm / 15 cm | Short enough for neat enclosures, long enough for small bench routing. |
| Connector type | Male pin header, both ends | Plugs directly into female IDC sockets or header pins. |
| Conductor material | Tin-plated copper (typical) | Low resistance for signal lines; check plating if corrosion is a concern. |
Practical note for South African buyers: a 40-way 15cm jumper is ideal for short runs inside enclosures or lab benches. If you need longer runs or individual signal separation to reduce crosstalk, consider longer ribbon lengths or single-core jumper bundles.
Before connecting, confirm the pin numbering and orientation on both boards. A common mistake is reversed pin order. For 40-way assemblies, mark pin 1 with the coloured stripe or a notch and align with the board's pin 1 silk-screen.
Connector A: [1 2 3 ... 40]
|--------------- ribbon 15cm --------------|
Connector B: [1 2 3 ... 40]
Ensure pin 1 locations match on both sides.

Communica stocks a wide range of cables and jumper assemblies across Samrand, Pretoria and Cape Town branches. Use the keyword when filtering product listings or searching the site to locate 40-way 15cm male-male ribbon jumpers. For procurement teams, account quotes and VAT invoices are available - prices are shown in ZAR and may vary with quantity and lead times.
Typical unit price for generic 40-way ribbon jumpers is modest; bulk orders for classroom sets or production runs should request a quote to check current stock and lead times. Example (estimate only): a single cable might be in the range of R20-R80 depending on brand and connector quality - confirm on the product page before purchase.
Search Communica's collections for ribbon cables and jumper leads, or browse by category: Connectors, Wire & Cable. Check the Samrand branch for immediate pickup or request a quote for bulk classroom or production needs. Use product filters to compare specs and confirm the cable length, conductor count and connector type before adding to cart.
