Amphe-PRB | Rugged Circular Connector Unlocks Reliable Power

Amphe-PRB: Rugged Circular Connector for Industrial Power

The Amphe-PRB from Amphenol Industrial Operations is a purpose-built solution designed to meet the evolving demands of high-power, mission-critical applications across industrial sectors. This robust connector supports secure power and signal transfer, even in environments where exposure to dust, moisture, vibration, or extreme temperatures threatens performance.

With the expansion of electrified systems in both stationary and mobile platforms, OEMs require durable, high-performance solutions that can stand up to environmental stress while maintaining exceptional electrical integrity. The Amphe-PRB addresses that need, delivering compact, lightweight, and field-proven connectivity in a circular form factor that simplifies integration across a wide array of systems.

Reliability Engineered for Demanding Applications

Built for harsh conditions, the Amphe-PRB leverages Amphenol’s engineering excellence to deliver consistent performance in power-dense installations. As industries embrace electrification—especially in energy storage and battery swap technologies—the demand for rugged, sealed connectors is accelerating. The Amphe-PRB was designed specifically to meet these rigorous expectations.

Applications range from battery management systems to power distribution units in challenging environments. The Amphe-PRB’s sealed, lightweight construction makes it ideal for off-road machinery, energy storage enclosures, and heavy-duty industrial equipment.

Sealed for Outdoor and Harsh Environment Use

This rugged connector provides sealed protection rated to IP67 when mated, helping isolate sensitive power and signal lines from dust, water, and contaminants. Its sealing capabilities extend longevity, reducing downtime and maintenance in the field. If your project demands high-endurance connectivity under mechanical shock or adverse weather, the Amphe-PRB is a proven choice.

The design integrates with Amphenol’s RADSOK® contact technology, ensuring lower insertion forces and optimized current-carrying capacity over time. This feature makes it particularly attractive for systems requiring repeatable, high-cycle mating.

Electrification-Ready and Flexible

As industries modernize toward electrified infrastructures, having a flexible and scalable interconnect solution is critical. The Amphe-PRB provides multiple pole options and accommodates a variety of cable sizes, making it adaptable to both new designs and retrofits. Whether deployed in mobile battery systems or stationary power platforms, it delivers dependable performance under continuous load.

Customers searching for lightweight sealed connectors with high current ratings will find the Amphe-PRB especially valuable. It complements Amphenol’s ePower-Lite Series for complete system-level electrification needs.
