Amphe-RXS | Power and Signal Connector in Harsh Environments

Reliable Power and Signal Connector for Electrification

The Amphe-RXS Connector Series is a compact, lightweight power and signal connector developed by Amphenol Industrial Operations to support the growing demands of electrified systems. Designed for hybrid and electric vehicles, battery systems, and other high-reliability environments, this series provides both high-voltage power and low-voltage signal capabilities in a single rugged housing. The integration of Amphenol’s proprietary RADSOK® technology ensures high current-carrying capacity and low contact resistance, making it an ideal power and signal connector solution for engineers designing high-performance systems with space and weight constraints.

It is especially well-suited for high-voltage and signal transmission in accordance with UL 1977 standards, supporting system compliance and safety requirements in electrified platforms.

Dual Functionality: Power and Signal in One Housing

One of the key benefits of the Amphe-RXS Series is its ability to combine power and signal functionality within the same connector. This reduces the number of interfaces required, streamlining installation while saving space and cost. As a power and signal connector, it offers exceptional versatility. With up to 13 contact positions available, the Amphe-RXS family can be configured to deliver high-voltage power and sensitive signal data transmission—making it ideal for battery modules, BMS systems, inverters, and onboard chargers. Whether used for communication lines or high-current distribution, the connector’s flexible design supports system-level integration.

Durable, Compact, Lightweight Shell

Constructed from a durable thermoplastic shell, Amphe-RXS connectors are significantly lighter than traditional metal-bodied alternatives, making them well-suited for applications where weight reduction is critical. Despite their lightweight profile, these power and signal connector solutions deliver exceptional performance in harsh operating environments. They are IP67 rated when mated, providing complete protection against dust ingress and temporary submersion. A secure locking mechanism ensures vibration resistance and reliable engagement, even under dynamic conditions.

High Current Performance with RADSOK® Technology

At the heart of the Amphe-RXS design is Amphenol’s field-proven RADSOK® technology. Engineered for low contact resistance and high amperage, RADSOK® contacts offer superior conductivity, increased reliability, and cooler operating temperatures. Depending on configuration, the Amphe-RXS connectors can support up to 120A per contact for power circuits, while maintaining excellent signal integrity for data lines. These performance characteristics make the Amphe-RXS an ideal power and signal connector for energy-dense systems such as battery packs and EV drivetrain architectures.

Flexible Configuration and Panel Mount Options

The Amphe-RXS Series offers extensive configurability, with options for 1 to 13 contact positions and availability in several keying and coding arrangements. Receptacles and plugs are available in both inline and flange-mount styles, and backshells can be added for strain relief and EMI shielding. Contacts are available in sizes 1.0mm, 3.6mm, 5.7mm, and 8.0mm to accommodate signal and power delivery requirements. The series also supports first-mate/last-break contact design for improved sequencing in high-power applications, further reinforcing its strength as a robust power and signal connector option.

Ideal for Next-Generation Electrification Platforms

From electric mobility to industrial automation and renewable energy storage, the Amphe-RXS connector series meets the evolving needs of modern system design. Its robust performance, multifunctional design, and flexible configuration make it the preferred power and signal connector for OEMs seeking high performance in a compact package. Whether you’re designing a modular battery architecture or integrating controls into a drivetrain, the Amphe-RXS delivers the connectivity performance and system simplification you need.
