RADSOK® PGY™ | High Current PCB Connector for Reliable Power

High Current PCB Connector for Direct-to-Board Power

The RADSOK® PGY is a high current PCB connector designed to meet the growing demand for compact, high-efficiency board-level interconnects. As a robust high current PCB connector, it simplifies power delivery in advanced electronic assemblies by allowing a cable lug to be mounted directly to the printed circuit board—eliminating the need for busbars and intermediate terminals.

Developed by Amphenol Industrial Operations, the PGY Series utilizes our proven RADSOK® contact technology to provide superior conductivity, minimal insertion force, and long-term performance. Supporting current ratings up to 120 A and designed for low voltage drop, the RADSOK® PGY is the ideal high current PCB connector for power supplies, datacenter hardware, renewable energy systems, and industrial inverters.

Optimized for Performance and Design Flexibility

This high current PCB connector features a vertical, through-board design that helps minimize system height while ensuring reliable, direct-to-board power transfer. Available in multiple contact sizes and board interface options, the PGY Series can be tailored to suit OEM board layouts. The 3.6 mm RADSOK® contact delivers outstanding power density and contact resistance as low as 0.1 mΩ—supporting compact design goals without compromising current capacity.

Whether used in EV infrastructure, power conversion modules, or high-performance computing, the PGY delivers safe, scalable power delivery in a compact footprint.

Proven RADSOK® Contact Technology

At the core of each PGY high current PCB connector is Amphenol’s proprietary RADSOK® contact. This radial design offers significantly greater contact surface area than conventional technologies, enabling lower contact resistance and improved thermal characteristics. As a result, the PGY Series supports long operating life even in high-cycling or harsh environments.

This contact system is widely adopted across power-critical industries, making PGY an excellent board-level option for system designers prioritizing reliability and efficiency.

Available Configurations and Mounting Options

The RADSOK® PGY is offered with press-fit or solder tail options to accommodate various assembly processes and environmental conditions. Its direct lug-over-contact interface helps reduce resistance and wiring complexity while enabling quick installation. The rugged design withstands thermal stress, shock, and vibration, making this high current PCB connector an ideal fit for transportation, renewable energy, and industrial applications.
