Buy Souriau 8STA Connectors in Australia
If you are looking to buy Souriau 8STA connectors in Australia, 12Volt Motorsports stocks the 8STA autosport range in Melbourne and ships Australia-wide. These are the connectors of professional motorsport, the same interconnect system running on Formula 1, WRC and MotoGP machinery, now available locally with the planning tools to spec them properly.
What Are Souriau 8STA Connectors?
The 8STA series is a miniature circular autosport connector derived from the MIL-DTL-38999 and JN1003 military specifications. A quick mating bayonet coupling, extreme shock and vibration tolerance, resistance to fuels and motorsport fluids, and more than 100 contact layouts across colour coded, keyed shells. Where a build outgrows general purpose sealed connectors, 8STA is the professional answer: smaller, lighter and denser, engineered so the harness never becomes the failure point.
Shell Sizes at a Glance
| Shell Size |
Character |
Typical Use |
| 01 | Ultra miniature, the smallest motorsport connector on the market | Single sensors where every gram and millimetre counts |
| 02 to 08 | Miniature, low contact counts | Sensors, small devices, lightweight branches |
| 10 to 16 | Mid density layouts | ECU interfaces, sub-harness disconnects, dash connections |
| 18 to 24 | High density, up to 68 plus contacts | Bulkhead disconnects and main harness interfaces |
Power contact options in the range carry up to 200 amps continuous, so battery, alternator and starter circuits can run through the same connector family as the signal wiring.
Plan Your Connectors With Our Free Tools
8STA part numbers are dense, shell size, insert arrangement, keyway, plating and contact type all live in the code. We built three free tools so you get the right parts first time.

8STA and Deutsch Autosport
Souriau 8STA and Deutsch Autosport AS connectors are direct equivalents built to the same autosport standards, and part numbers convert between the two systems. If your existing harness or build sheet is specified in Autosport part numbers, run them through the cross reference tool and order the matching 8STA parts.
Where 8STA Fits in Your Build
Deutsch DTM and Amphenol ATM cover sealed sensor wiring brilliantly at club level. Step up to 8STA for bulkhead disconnects, ECU interfaces and professional harness architecture where density, weight and positive bayonet coupling matter. Wire it in M22759/32 Tefzel, sleeve in Raychem DR25, and finish transitions with proper adhesive boots. That combination is a professional motorsport harness, full stop.

They are direct equivalents built to the same autosport standards, and part numbers convert between the two systems. Our free Souriau and Autosport cross reference tool converts part numbers in both directions.
When should I use 8STA instead of Deutsch DTM?
DTM and ATM cover sealed sensor wiring brilliantly at club level. Step up to 8STA when the build demands maximum weight and space saving, higher density layouts, positive bayonet coupling and true autosport pedigree: bulkhead disconnects, ECU interfaces, professional level harness architecture.
What do the keyway colours mean on 8STA connectors?
The shells come in colour coded keyway options so multiple connectors of the same size can sit side by side without cross mating. Same size, different key, no mistakes in the pit lane.
What contacts do 8STA connectors use?
Crimp contacts across sizes from 26 up to high current options, with power contacts in the range handling up to 200 amps continuous for battery, alternator and starter circuits. Contacts need the correct autosport crimp tooling, call us to spec the tools with the connectors.
Do you ship Souriau connectors Australia-wide?
Yes. We ship to Sydney, Brisbane, Adelaide, Perth, Canberra, Hobart, Darwin and everywhere in between, usually same or next business day.
