Amphenol Automotive Connectors: Product Catalog & Series Classification Guide
Deep dive into Amphenol automotive connector product families including AT Series, ATM, ATHD, MicroSpace, FlexFast and other key series for automotive applications, and how they compare to TE Connectivity.
Introduction to Amphenol Automotive
Amphenol Corporation, founded in 1932 and headquartered in Wallingford, Connecticut, is the world's second-largest automotive connector manufacturer after TE Connectivity, holding approximately 8-10% of the global automotive connector market share. With annual revenues exceeding $15 billion (2025), Amphenol's automotive division spans multiple business units including Amphenol Automotive Connection Systems, Amphenol Sine Systems, Amphenol LTW, and Amphenol Communications Solutions.
Amphenol's product philosophy centers on three pillars: environmental robustness (IP67/IP68/IP69K sealing as standard across most product lines), mechanical durability (heavy emphasis on CPA/TPA mechanisms and vibration resistance), and technological innovation (early adoption of LV214 Severity-3 testing and automotive fiber optics). Their connectors are designed to meet or exceed both USCAR-2 (North American) and LV214 (European) requirements, making them a preferred choice for global OEM programs.

How to Select an Amphenol Connector
- Identify the application environment: Interior (IP00 possible), engine bay (IP67 minimum), underbody (IP69K preferred)
- Determine electrical requirements: Voltage class (12V/48V/HV), current per contact, signal vs. power
- Choose the right platform:
- Heavy-duty power in harsh environment → AT/ATHD Series
- High-density signal/PCB → MicroSpace/MicroSpaceXS
- Flex circuit connection → FlexFast
- Battery interconnect → DURASWAP
- RF/antenna → FAKRA/Coax
- EV charging → charge|mate / Charge Inlet
- Verify mating compatibility: Amphenol connectors are generally intermateable with same-series products, but not cross-compatible with TE or Molex equivalents
- Check tooling requirements: While many Amphenol connectors use standard crimp tools, always verify with the product specification
