GTC-E Series | High Power Connectors with Proven Reliability

The GTC-E Series from Amphenol Industrial Operations delivers a next-generation solution for engineers and OEMs seeking high power connectors that are compact, robust, and optimized for electric and hybrid-electric powertrains. Designed to perform in harsh environments, this innovative connector series offers high voltage and high current capabilities in a sealed, user-friendly package.

High Power Performance in a Compact Footprint

Built to meet the growing demands of electrification, the GTC-E Series enables safe, efficient transfer of high voltage and high current with minimal footprint. Engineered with Amphenol’s field-proven RADSOK® technology, these connectors minimize contact resistance and maximize current-carrying capacity, even under continuous vibration and thermal stress. With support for up to 1000V and 250A, these high power connectors ensure dependable performance in demanding powertrain environments.

As electrified systems become more compact and more powerful, space constraints and thermal requirements are increasingly critical. The GTC-E Series addresses both, offering a high-density solution that delivers exceptional electrical performance without sacrificing durability or ease of use.

Reliable Sealing and Easy Assembly

The GTC-E Series features a rugged two-piece construction that simplifies installation and improves long-term reliability. Its IP67 and IP6K9K sealing ensures protection against water, dust, and other contaminants, making it ideal for harsh outdoor and mobile environments.

The twist-lock bayonet coupling design allows for secure, tool-free mating and unmating, reducing assembly time and lowering installation costs. Amphenol’s reverse bayonet coupling system has been recognized as an industry-leading solution for field installation — as highlighted in a PR Newswire feature on its ease of use in rugged environments.

An integrated strain relief system protects internal components from mechanical stress, while optional secondary locking features and HVIL contacts enhance safety during operation and service.

Key Features of the GTC-E Series

• Rated for up to 1000V and 250A continuous operation
• RADSOK® contact technology for low resistance and high reliability
• Sealed to IP67 / IP6K9K when mated
• 1-, 2-, and 3-pole configurations
• Twist-lock bayonet coupling with secondary lock option
