Amphenol now offers three compact, high-amperage, ROHS-compliant Radsok PCB connectors for a variety of power bus applications.

These applications include, but are not limited to, high-power bus assembly utilities, power-to-board servers, power-to-box servers and battery power/chargers for electric vehicles.

Amphenol’s Radsok technology uses a hyperbolic, stamped grid configuration that ensures a large, coaxial, face-to-face surface-area engagement to maximise heat dissipation and reduce failures.

The Radsert, Powerblok and PGY connectors not only feature dependable operation, but also offer more surface space within a circuit board design while eliminating threaded connection failures.

They are suitable for use in high-current, single-point connections.

The Radsert connector offers the smallest footprint of Amphenol’s new PCB line, opening up the most surface space for design flexibility.

This new connector gives designers the option of bringing power to the board from busbars suspended above or below the board and its components.

Radsert is offered in press-fit and solder versions, and is available in either a 2.4mm size and rated for up to 35A or a 3.6mm size and rated for up to 70A.

It is designed for a board thickness of 6.35 +/-0.0635mm with custom sizes available for specific applications.

Also able to provide 70A to a PCB, the 12.7 x 12.7mm Powerblok features a radial design that has a touch-proof cover and many points of contact.

The connector’s backplane power interface employs the use of compliant pins that are press-fit into the PCB.

This helps to facilitate a solid connection and an even signal flow.

The Powerblok’s small footprint is advantageous to engineers who have limited size and weight requirements for their PCB.

Available in 3.6mm carrying up to 70A and 5.7mm carrying up to 120A, the PGY is an orthogonal card edge connector that delivers high amperage in a small housing.

The PGY connects to the PCB through a solder reflow process.
