Amphenol ATM, AT and ATP connectors are sealed automotive connectors commonly used in motorsport, performance automotive, off-road, industrial and harsh-environment wiring applications. They are available in different sizes depending on the current draw, wire size and number of circuits required.

What Are Amphenol ATM, AT and ATP Connectors?

Amphenol ATM, AT and ATP connectors are part of the Amphenol sealed connector range. They are designed for different current levels and wire sizes, while keeping the same general sealed connector style used throughout motorsport and automotive wiring.

Amphenol ATM connectors are the compact low-current option. Amphenol AT connectors are the general-purpose automotive option. Amphenol ATP connectors are the larger high-current option.

Amphenol ATM vs AT vs ATP Connectors

The easiest way to choose the right Amphenol connector is to match the connector series to the circuit current and wire size. Do not choose only by pin count. A 2 pin ATM, 2 pin AT and 2 pin ATP are not the same thing.

When Should I Use Amphenol ATM Connectors?

Use Amphenol ATM connectors when you need a compact sealed connector for low-current circuits. They are a good choice for sensors, ECU signal wiring, CAN wiring, switch inputs, dash wiring and small removable harness branches.

Amphenol ATM connectors use size 20 contacts and are commonly used where space is limited and the current draw is low. They are not the right choice for high-current circuits such as fuel pumps, thermofans or large power feeds.

When Should I Use Amphenol AT Connectors?

Use Amphenol AT connectors when you need a sealed connector for general-purpose automotive or motorsport wiring. They are a good middle-ground connector when ATM is too small and ATP is larger than needed.

Amphenol AT connectors are commonly used for engine bay wiring, lighting circuits, injectors, solenoids, switch wiring, relay circuits, removable harness sections and general low-to-medium current automotive wiring.

When Should I Use Amphenol ATP Connectors?

Use Amphenol ATP connectors when the circuit current or wire size is too large for Amphenol ATM or Amphenol AT connectors. ATP connectors are the better choice for higher-current sealed wiring applications.

Amphenol ATP connectors are commonly used for fuel pumps, thermofans, water pumps, power feeds, heavier auxiliary circuits and high-current removable harness sections.

Can Amphenol Connectors Be Used With Deutsch Connectors?

Yes. Amphenol ATM, AT and ATP connectors are commonly used as compatible alternatives to Deutsch DTM, DT and DTP connectors. In most applications, matching Amphenol and Deutsch connectors of the same series type, pin count and configuration can mate together.

The correct matching is:

For best results, always match the correct series, plug and receptacle style, pin count, keying, contact size, terminal type and wire size. Do not mix ATM with DT or DTP, AT with DTM or DTP, or ATP with DTM or DT. They are different connector sizes.

What Should I Use With Amphenol Connectors?

Amphenol ATM, AT and ATP connectors are commonly used with Tefzel M22759/32 wire, Raychem DR25 heatshrink, Sumitomo W5DL adhesive heatshrink, ECU plugs and pins and proper crimp tooling when building professional motorsport wiring harnesses.

The connector only works properly when the full assembly is correct. That means the right housing, wedge, terminal, seal, wire size and crimp. A poor crimp or wrong terminal can cause voltage drop, heat, intermittent faults and long-term reliability issues.

Frequently Asked Questions

Where can I buy Amphenol connectors in Australia?

12Volt Motorsports stocks Amphenol ATM, AT and ATP connector kits in Australia. We are based in Melbourne and ship Amphenol connectors Australia-wide.

What is the difference between Amphenol ATM, AT and ATP connectors?

Amphenol ATM connectors are compact low-current connectors using size 20 contacts. Amphenol AT connectors are general-purpose sealed automotive connectors using size 16 contacts. Amphenol ATP connectors are larger high-current connectors using size 12 contacts.

Which Amphenol connector should I use for sensor wiring?

For most sensor wiring, ECU signal wiring, CAN wiring and switch inputs, Amphenol ATM connectors are usually the best choice because they are compact and suited to low-current wiring.

Which Amphenol connector should I use for general automotive wiring?

For general automotive and motorsport wiring, Amphenol AT connectors are usually the best middle-ground option. They are commonly used for lighting, solenoids, injectors, switches, relay circuits and removable harness sections.

Which Amphenol connector should I use for fuel pumps or thermofans?

For higher-current circuits such as fuel pumps, thermofans, water pumps and larger power feeds, Amphenol ATP connectors are usually the better choice because they support larger terminals and higher-current wiring.

Can Amphenol connectors mate with Deutsch connectors?

Yes. Amphenol ATM, AT and ATP connectors are commonly used as compatible alternatives to Deutsch DTM, DT and DTP connectors. Match ATM with DTM, AT with DT, and ATP with DTP. Always match the pin count, connector style and contact size.

Are Amphenol connectors the same as Deutsch connectors?

They are not the same brand, but Amphenol A-Series connectors are commonly used as compatible alternatives to the matching Deutsch connector families. ATM matches DTM, AT matches DT, and ATP matches DTP.

Do Amphenol connectors use the same contact sizes as Deutsch connectors?

Yes, the matching connector families use the same contact size style. Amphenol ATM and Deutsch DTM use size 20 contacts. Amphenol AT and Deutsch DT use size 16 contacts. Amphenol ATP and Deutsch DTP use size 12 contacts.

Are Amphenol connectors waterproof?

Amphenol ATM, AT and ATP connectors are sealed connectors designed for harsh environments. When assembled correctly with the correct terminals, seals and wedges, they provide strong protection against moisture, dirt and vibration.

Do I need a special crimp tool for Amphenol connectors?

Yes. Amphenol contacts should be crimped with the correct tool for the terminal type and contact size. Correct crimping is critical for reliability, current capacity and long-term serviceability.
