Buy Amphenol AT Connectors in Australia
If you are looking to buy Amphenol AT connectors in Australia, 12Volt Motorsports stocks AT connector kits from 2 to 12 way for motorsport wiring, general automotive circuits, solenoids, relays, lighting and medium current harness sections. We are based in Altona Meadows in Melbourne's western suburbs and ship Australia-wide.
The AT series is Amphenol's general purpose sealed connector, engineered to be fully intermateable with Deutsch DT. Same fit, same function, typically a sharper price. Every kit includes the plug, receptacle, both wedgelocks and size 16 contacts, one complete sealed connection per kit.
What Are Amphenol AT Connectors?
Amphenol AT connectors are thermoplastic sealed connectors using size 16 contacts rated 13 amps per pin on 14 to 20 AWG wire. Mated connectors are rated IP68 and IP69K, sealed with high temperature silicone seals, held by an integrated latch, with a wedgelock aligning and locking the contacts. They are used across automotive, motorsport, off-road, marine, agriculture and heavy equipment wiring in harsh environments.

AT and Deutsch DT, Fully Intermateable
AT was designed to be compatible with the existing industry standard connector, which means an AT plug clicks straight into a Deutsch DT receptacle, contacts interchange and sealing performs the same. Nothing in your harness design changes. Match pin count, plug and receptacle style and terminal size as usual, and do not mix AT with Deutsch DTM or DTP, those are different series with different contacts.

What Should I Use With Amphenol AT Connectors?
Wire AT circuits in 18 to 14 AWG Tefzel depending on load, sleeve in Raychem DR25 and seal exits with Sumitomo W5DL. A correct closed barrel crimp is critical for reliability in heat, vibration and moisture.
Frequently Asked Questions
Where can I buy Amphenol AT connectors in Australia?
12Volt Motorsports stocks Amphenol AT connector kits from 2 to 12 way in Melbourne and ships Australia-wide. Housings, wedgelocks and size 16 contacts are available on request.
Are Amphenol AT connectors compatible with Deutsch DT?
Yes, fully intermateable. An AT plug mates with a DT receptacle and vice versa, contacts interchange and the seals do the same job. You can mix the two families freely in one harness.
What are Amphenol AT connectors used for?
General purpose automotive and motorsport wiring: solenoids, relays, lighting, actuators, small motors and medium current removable harness sections.
What is the current rating of Amphenol AT connectors?
13 amps per pin using size 16 contacts on 14 to 20 AWG wire. For compact sensor circuits use ATM at 7.5 amps, and for fuel pumps and power feeds use ATP at 25 amps.
Are Amphenol AT connectors waterproof?
Yes. Mated AT connectors are rated IP68 and IP69K, sealed with high temperature silicone seals and locked with an integrated latch. Assembled correctly they handle immersion, pressure washing, dirt and vibration.
Why choose Amphenol AT over Deutsch DT?
Same fit, same function, typically a sharper price. AT was engineered to be compatible with the existing industry standard, so nothing in your harness design changes. Buy whichever is in stock or better value.
Should I use Amphenol AT or ATM connectors?
Use AT where the circuit carries real current or the wire is 14 to 20 AWG: solenoids, relays, lighting. Use ATM for compact low current sensor and signal wiring on 16 to 22 AWG.
Are Amphenol AT connectors the same as Deutsch DT?
Not the same brand, but the same style of sealed connector system, engineered to be compatible. AT is commonly used as a direct alternative to DT in motorsport, automotive, off-road and industrial wiring.
What is in an AT connector kit?
Each kit includes the plug, the receptacle, both wedgelocks and the correct number of size 16 contacts, everything needed for one complete sealed connection.
Do I need gold or nickel contacts?
Our AT kits ship with nickel plated contacts, correct for general purpose and power circuits. Gold plated contacts suit millivolt level signal circuits and can be ordered in on request.
What crimp tool do AT contacts need?
Solid barrel size 16 contacts need a closed barrel crimper such as the HDT-48-00 style tool, the same tooling used for Deutsch DT contacts.
Do you ship Amphenol AT connectors Australia-wide?
Yes. We ship to Sydney, Brisbane, Adelaide, Perth, Canberra, Hobart, Darwin and everywhere in between, usually same or next business day.
