Amphenol Industrial announces SAE J1772 series connector

Amphenol Industrial Operations (AIO) introduces the ER SAE series J1772, a state-of-the-art charging solution designed for the evolving electric vehicle (EV) market. As electric mobility expands, reliable, efficient, and durable charging systems are critical. The ER SAE series J1772 meets these demands, offering a robust solution that provides high-quality performance for electric, hybrid-electric, and e-mobility vehicles. This product page dives deep into the ER SAE series J1772’s key features, benefits, and applications, demonstrating how it leads the market in providing sustainable, high-performance charging.
The ER SAE series J1772 is designed according to the SAE J1772 standard, which governs alternating current (AC) charging systems for electric vehicles in North America. This standard ensures compatibility and safety across multiple EV models, offering both Level 1 (120VAC) and Level 2 (250VAC) charging. The ER SAE series J1772 connector is ideal for charging stations and electric vehicle supply equipment (EVSE), providing an efficient, reliable charging interface between the power grid and the vehicle’s battery.
The ER SAE series J1772 charging cable provides a current rating of up to 80A, with a voltage capacity of 250VAC. Its ergonomic design and durable construction ensure it meets the high demands of the electric vehicle market, withstanding more than 10000 mating cycles and performing in challenging environments, from icy conditions to high temperatures.
Features
- High current and voltage ratings
- The ER series SAE J1772 supports a wide range of power needs, with current ratings of 20A, 32A, 40A, 50A, and up to 80A at a voltage capacity of 250VAC. These specifications make it a versatile solution for both private and commercial charging stations, supporting everything from slow, overnight charging to faster, high-current applications.
- Low insertion and extraction Forces
- A key challenge in EV charging is ensuring ease of use without sacrificing durability. The ER series SAE J1772 overcomes this challenge with a unique contact design that reduces insertion and extraction forces to less than 75N. This makes the connector easy to operate for everyday use, while ensuring durability and longevity.
- Durable, environmentally sealed design
- Built to withstand harsh environments, the ER series SAE J1772 is rated IP67, providing protection against dust, water, and contaminants. It also features Type 3S protection, ensuring it can operate in environments with ice or other extreme conditions. Its rugged design ensures reliable performance, even after prolonged exposure to salt spray and harsh elements.
- Ergonomic, user-friendly operation
- The ER series SAE J1772’s integrated handle is designed for ease of use. Its ergonomic shape and low insertion/withdrawal force make it comfortable for users, whether they are operating the charging gun at home or in a commercial setting. Additionally, the connector’s design minimizes the risk of damage to both the plug and the vehicle’s receptacle.
- High mating cycles
- One of the standout features of the ER series SAE J1772 is its ability to withstand more than 10000 mating cycles. This ensures a long lifespan for both the connector and the vehicle inlet, making it an ideal choice for high-use applications such as public charging stations.
- Safety features
- The ER series SAE J1772 incorporates a secondary locking mechanism to prevent unintentional disconnection during charging. This feature ensures that charging sessions are safe and uninterrupted, providing peace of mind to users.
