Features and Benefits

As the demand for product miniaturization continues to rise, manufacturers require more power within a smaller footprint. Also, engineers require more design flexibility as additional functionalities are required in products. Operators face more complex procedures requiring multiple tasks that lead to mis-mating and increased mating force.

Designed to meet environmental, health and safety (EH&S) regulations and reduce mating force, Micro-Fit+ Connectors offer colored, mechanically keyed connectors for easy assembly with selective mating, helping prevent connector mis-mating. Operators benefit from easier assembly while increasing productivity and lowering risk of injury. These connectors also offer up to a 40% mating-force reduction, minimizing operator fatigue which can result in increased productivity.

Addressing the need for more power within a smaller footprint, Micro-Fit+ OCP M-PIC 12V Connectors support up to 864W in peripheral devices as defined within OCP M-PIC specifications. This connector solution enables high-power delivery without increasing the connector size, making it ideal for data center and server applications. Additionally, Micro-Fit+ products are halogen-free and Glow Wire capable, allowing manufacturers to adhere to environmental compliance and operator safety standards, including European regulations.

Exceptional Space Savings

With its unique keying design, the Micro-Fit+ Connectors offer up to 13.5A with a 3.00mm pitch to deliver high-current capacity for a diverse range of applications, using the same amount of space that lower-current connectors occupy.

OCP and PCIe Specified

For increased power, Micro-Fit+ OCP M-PIC 12V Connectors support up to 864W in peripheral devices as defined within OCP M-PIC specifications. This connector solution delivers high power without increasing the connector size, offering significant space savings for enhanced functionality.

Frequently Asked Questions

Are Micro-Fit and Micro-Fit+ intermatable?​

No, they do not mate. The standard Micro-Fit product family and Micro-Fit+ product family do not mate together as they have different keying and polarization. ​

What is the benefit of using Micro-Fit+ over standard Micro-Fit?​

Micro-Fit+ has a higher current rating in a compact package, perfect for automotive or datacom end applications.​

Why would customers be interested in Micro-Fit+ having a lower mating force compared to standard Micro-Fit part numbers?​

Provides improved overall ergonomics within the connector system. A lower mating force is a design factor intended to maximize productivity by minimizing operator fatigue and discomfort.

What are Micro-Fit+ OCP M-PIC Connectors?​

Micro-Fit+ OCP M-PIC Connectors are hybrid power and signal connectors standardized by the Open Compute Project under the Data Center-Modular Hardware System (DC-MHS) initiative. It is designed to simplify and standardize the connectivity from the host processor module to peripheral devices within servers.​
