Amphe-PRB Flange-Mount Receptacle Expands 1U Server Connectivity

The Amphe-PRB flange-mount receptacle expands Amphenol Industrial Operations’ power connector portfolio with a five-position configuration designed for compact server and data center equipment. The low-profile design accommodates 1U server architectures while incorporating 3.6 mm RADSOK® contact technology for high-current power connectivity.

As server power requirements increase, engineers must balance current-carrying capability, thermal performance, and limited equipment space. The new configuration addresses these challenges through compact mechanical packaging, low contact resistance, and flexible cable size options.

Amphe-PRB Series Expansion for Server Applications

The Amphe-PRB Series provides power connectivity for industrial applications including inverter systems, energy storage, data and telecommunications equipment, and factory automation. Its reverse-bayonet connector platform combines lightweight plastic construction with a rugged coupling design for demanding electrical environments.

Amphenol Industrial Operations has extended the series with a five-position flange-mount receptacle intended for server and data center equipment. This configuration focuses on a different engineering challenge: delivering high-current power connections within restricted equipment dimensions.

The new receptacle features a low-profile construction designed to fit into 1U server equipment. By providing a compact mounting interface, it allows system designers to consider connector placement alongside other space-sensitive components in server power distribution architectures.

High-Current RADSOK® Contact Technology

The five-position Amphe-PRB configuration incorporates 3.6 mm RADSOK® contacts, designed to deliver high current-carrying capability with low electrical contact resistance.

Contact resistance is an important consideration in server power systems because electrical losses at connection points contribute to heat generation. As power requirements increase within densely packaged equipment, maintaining efficient electrical interfaces becomes particularly important. At the facility level, ASHRAE’s guidance on data center energy and thermal efficiency addresses broader thermal management and cooling considerations.

The RADSOK® contact system helps limit resistive losses and associated temperature rise. The five-position arrangement integrates multiple power contacts into a compact connection interface, supporting the electrical and mechanical packaging requirements of server equipment.

Engineers should evaluate the applicable current and voltage ratings for their selected configuration, along with conductor size, operating conditions, and system-level thermal requirements.

Amphe-PRB Flange-Mount Receptacle Design and Integration

The Amphe-PRB flange-mount receptacle is designed for equipment where connector height and available installation space are critical design constraints. Its low-profile configuration supports mechanical integration into 1U server architectures without requiring the vertical clearance associated with larger connection interfaces.

The flange-mount arrangement provides an equipment connection point, while multiple cable size options offer flexibility when selecting conductors for different power requirements.

These characteristics allow engineers to consider electrical performance, cable routing, thermal management, and mechanical integration together during equipment design.

Key engineering advantages include:

• Five-position flange-mount receptacle configuration
• Low-profile design suitable for 1U server equipment
• 3.6 mm RADSOK® contact technology
• High current-carrying capability
• Low contact resistance
• Multiple cable size options

Server and Data Center Applications

Server and data center power systems require interconnect solutions that accommodate increasing electrical demands within defined mechanical packaging limits. In 1U configurations, limited vertical clearance places additional constraints on connector selection and mechanical design. Separately, the U.S. Environmental Protection Agency’s ENERGY STAR enterprise server program addresses energy efficiency and power management in server equipment.

The new Amphe-PRB receptacle addresses these requirements with a compact mounting profile and high-current RADSOK® contact technology. Its low contact resistance supports thermal design considerations, while cable size options provide flexibility for different equipment configurations.

Targeted applications include:

• 1U server equipment
• Data center power distribution
• Server power interconnections
• Space-constrained data and telecommunications equipment

This expansion broadens the Amphe-PRB portfolio beyond its established industrial applications and provides engineers with an additional power connection configuration for compact server infrastructure.
