Buy Amphenol ATP Connectors in Australia
If you are looking to buy Amphenol ATP connectors in Australia, 12Volt Motorsports stocks ATP connector kits in 2 and 4 way for high current motorsport wiring, fuel pumps, thermofans, power feeds, off-road wiring and custom harness builds. We are based in Altona Meadows in Melbourne's western suburbs and ship Australia-wide.
The ATP is the high current member of the Amphenol A series, engineered to be fully intermateable with Deutsch DTP. Same fit, same function, typically a sharper price. Every kit includes the plug, receptacle, both wedgelocks and size 12 contacts, one complete sealed connection per kit.
What Are Amphenol ATP Connectors?
Amphenol ATP connectors are thermoplastic sealed connectors using size 12 contacts rated 25 amps per pin on 12 to 14 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 built for high current circuits in harsh automotive, motorsport, marine and heavy equipment environments.
Amphenol ATP Kit Range
ATP comes in lower pin counts because it is built around larger high current terminals. Choose from the number of high current circuits required. Click a kit to shop it.
ATP and Deutsch DTP, Fully Intermateable
ATP was designed to be compatible with the existing industry standard connector, which means an ATP plug clicks straight into a Deutsch DTP 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 ATP with Deutsch DT or DTM, those are different series with different contacts.

What Should I Use With Amphenol ATP Connectors?
Wire ATP circuits in 14 or 12 AWG Tefzel, sleeve in Raychem DR25 and seal exits with Sumitomo W5DL. For circuits beyond 25 amps, see our power distribution range including TE SurLok bolted connections. A correct closed barrel crimp matters most on high current circuits, where a poor joint makes heat.
Frequently Asked Questions
Where can I buy Amphenol ATP connectors in Australia?
12Volt Motorsports stocks Amphenol ATP connector kits in 2 and 4 way in Melbourne and ships Australia-wide. Housings, wedgelocks and size 12 contacts are available on request.
Are Amphenol ATP connectors compatible with Deutsch DTP?
Yes, fully intermateable. An ATP plug mates with a DTP 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 ATP connectors used for?
Higher current wiring such as fuel pumps, thermofans, water pumps, power feeds, heavier auxiliary circuits and high current removable harness sections.
What is the current rating of Amphenol ATP connectors?
25 amps per pin using size 12 contacts on 12 to 14 AWG wire. Always check the actual circuit current and wire size before choosing the connector.
Are Amphenol ATP connectors waterproof?
Yes. Mated ATP 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 ATP over Deutsch DTP?
Same fit, same function, typically a sharper price. ATP 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 ATP or AT connectors?
Use AT for medium current general purpose circuits up to 13 amps. Use ATP where the current draw or wire size is beyond AT, such as larger fuel pumps, thermofans and heavier power feeds.
What if my circuit draws more than 25 amps?
Above 25 amps per pin you are beyond the ATP series. Options include bolted high current connections like the TE SurLok range in our power distribution collection. Call us and we will spec the right connection.
Should I use Amphenol ATP for sensor wiring?
No, ATP connectors are usually too large for normal sensor wiring. For sensor and ECU signal circuits use Amphenol ATM, and for medium current general circuits use Amphenol AT.
Are Amphenol ATP connectors the same as Deutsch DTP?
Not the same brand, but the same style of high current sealed connector system, engineered to be compatible. ATP is commonly used as a direct alternative to DTP in motorsport, automotive, off-road and industrial wiring.
What is in an ATP connector kit?
Each kit includes the plug, the receptacle, both wedgelocks and the correct number of size 12 contacts, everything needed for one complete sealed connection.
What crimp tool do ATP contacts need?
Solid barrel size 12 contacts need a closed barrel crimper such as the HDT-48-00 style tool set for size 12. Correct crimping matters most on high current circuits where a poor joint makes heat.
Do you ship Amphenol ATP connectors Australia-wide?
Yes. We ship to Sydney, Brisbane, Adelaide, Perth, Canberra, Hobart, Darwin and everywhere in between, usually same or next business day.
