Amphenol presents Minitek® Pwr, an exceptional unsealed wire-to-wire and wire-to-board connector system designed to cater to mid-power applications. With its versatile pitch sizes of 3.00mm, 4.20mm, and 5.70mm, and an impressive range of current ratings from 5A to 28A, Minitek® Pwr is the ultimate choice for demanding electrical connections.

Features and Benefits

One of the standout features of Minitek® Pwr is its innovative flexing beam design, which ensures a low insertion force during mating. This design allows for a hassle-free and secure connection, minimizing the risk of damage during the mating and unmating process. Additionally, the connectors boast fully polarized interfaces, preventing accidental mismating and ensuring reliable and consistent performance.

The Minitek® Pwr connectors are equipped with finger proof, scoop-proof contacts, offering enhanced protection to the contacts during mating and unmating operations. This feature greatly reduces the potential for contact damage, promoting longevity and reliability in your electrical systems.

Furthermore, the connectors feature a fuss-free malleability with a blind-mate interface (BMI), which provides a self-aligning feature molded into the housings. This ensures a seamless and accurate connection, even in challenging installation scenarios.

Minitek® Pwr connectors incorporate a positive locking system that securely mates the connectors, effectively preventing accidental un-mating. This robust locking mechanism guarantees a stable and uninterrupted electrical connection, even in demanding environments. Additionally, the wire-to-board version of the connectors offers Terminal Position Assurance (TPA), further enhancing the reliability and integrity of your connections.


Minitek® Pwr connectors find extensive applications across various industries. In the consumer sector, they are ideal for air-conditioners, microwave ovens, set-top boxes, refrigerators/freezers, printers/copiers, vending machines, washing machines, and gaming equipment. In the medical field, they are suitable for hospital beds, defibrillators, patient monitors, and ultrasound equipment. For industrial applications, Minitek® Pwr connectors are perfect for, Energy storage, Warehouse Robotics, industrial control panels, Factory automation drives and motors. They are also well-suited for networking and data communications in HDD applications, hot plug servers, NVR servers, server fan applications, Rack Servers, OCP DC-MHS, desktop computers, and motherboards. Additionally, in telecommunications, they excel in 1U rack boxes, Wi-Max boxes, interface converters, customer premises equipment, hubs, power supplies, and distribution.

The three pitch sizes of the connector family are intended to balance out between current-carrying efficiency and space-savings. For example, the 5.7mm pitch version is a heavy haul among medium power applications while the 3mm pitch is suitable for smaller footprint designs. Both 3mm and 4.2mm have higher current versions depending on the application at hand.

The 3mm pitch version is also popular in datacom applications due to its support for 12V requirements in High Performance Computing applications as well as the Open Compute Project (OCP). Two variants are offered, one to power GPU cards while carrying sideband signals at PCIe Gen 5 data rates, and another to manage power distribution in OCP racks. These solutions respectively addressed as CEM5 12VHPWR and the 12VPICPWR are hybrid versions that besides conducting power, allow sideband protocol signals to be passed along.
