Amphenol Automotive Connectors


Amphenol is a leading supplier of advanced interconnect systems for automotive safety devices and expanding onboard electronics in automobiles. These applications include entertainment, communication, navigation, and telematics modules, as well as engine control, sensors, actuators, and auxiliary motors. In addition, Amphenol has developed leading solutions for hybrid-electric vehicles and drive systems and is working with leading global customers to proliferate these advanced interconnect products into next-generation automobiles.


Amphenol Sine's A Series Automotive Connectors are designed as a high-performance solution for Heavy Equipment, Agricultural, Automotive, Military, Alternative Energy and other demanding interconnect architectures.

The AT Series™ connectors contain superior environmental seals, seal retention capabilities and feature Amphenol Sine Systems RockSolid™ Contact technology. In addition, all of our AT Series™ connectors have been developed to be completely compatible with all other existing standard products industry-wide. The connector design incorporates an integral latching system that ensures a definitive electrical and mechanical connection. Connector housings are manufactured with a thermoplastic material that is not only durable, but has excellent UV resistance, dielectric/mechanical properties and environmentally RoHS compliant. The sealing system is comprised of a front and rear silicone, multi-sealing, perimeter against environmental ingress. Contacts are derived from quality copper alloy to ensure an electrically-reliable connection. For applications demanding higher levels of performance, you can rely on our RockSolid™ contact technology.

Amphenol Sine Systems AHD Series™ Connectors were developed in response to the overwhelming need for an economic alternative to today's existing diagnostic product options. Designed specifically as a cost-conscious, reliable alternative, intermateable to industry standard 6 and 9 pin connectors, the AHD Series™ is ideal for any situation where either controlled and/or uncontrolled environmental conditions exist.

Amphenol Sine Systems AHD Series™ Connectors offer both a smooth, non-sealing option for controlled applications, as well as an environmentally-sealed, threaded option for more demanding applications. The same applies for DiagnosticGrade™ Cable Assemblies that provide both options for designers.


Amphenol Industrial's ePower line is designed for a variety of applications including, but not limited to, power converters, hybrid electric vehicles, heavy equipment electrification, two-and three-phase motors and starter generators. Using innovative RADSOK® technology the ePower series has a 40% smaller footprint, higher amperage, lower T-rise, and less resistance when mating. One ePower 400A connector can replace three conventional connectors, saving space and cost.
