Just How Small Is a MICRO-D Connector?

When engineers hear “MICRO-D,” they usually think about compact packaging, lightweight systems, and high-density interconnects for space-constrained applications.

But seeing one next to a quarter puts the scale into perspective immediately.

NorComp’s machined MICRO-D connectors deliver rugged interconnect performance in an incredibly compact footprint, helping engineers reduce system size without sacrificing reliability.

Designed for Space-Constrained Applications

As electronics continue shrinking, connector size becomes a major design consideration. Robotics, medical devices, portable instrumentation, aerospace systems, and embedded electronics all demand more functionality in less space.

Compared to traditional D-Sub interfaces, MICRO-D connectors allow engineers to significantly reduce connector footprint while maintaining dependable electrical and mechanical performance.

That can help support:

Smaller enclosure designs
More usable PCB real estate
Reduced overall system weight
Improved cable routing flexibility
Higher packaging efficiency

Seeing the Scale

NorComp’s machined MICRO-D connectors are remarkably compact.

The lowest pin count 9-position MICRO-D connector occupies only a fraction of the area of a U.S. quarter.

The images below show actual NorComp MICRO-D products beside a quarter for scale reference.

MICRO-D Panel Cutout Dimensions

NorComp 580-M and 581-M Series MICRO-D connectors are available in 9, 15, and 25 position sizes with front and rear mount panel cutout options.

MICRO-D Front Mounted Panel Cutouts

Configuration	A	B	C
9 Position Male	14.35 mm	10.10 mm	6.80 mm
9 Position Female	14.35 mm	7.85 mm	3.00 mm
15 Position Male	18.20 mm	13.90 mm	6.80 mm
15 Position Female	18.20 mm	12.06 mm	3.00 mm
25 Position Male	24.55 mm	20.25 mm	6.80 mm
25 Position Female	24.55 mm	18.41 mm	3.00 mm

MICRO-D Rear Mounted Panel Cutouts

Configuration	A	B	C
9 Position	14.35 mm	10.41 mm	6.50 mm
15 Position	18.20 mm	14.22 mm	6.50 mm
25 Position	24.55 mm	20.57 mm	6.50 mm

Small Size. Rugged Performance.

The value of MICRO-D connectors is not simply miniaturization. It is what that smaller footprint enables in real-world systems.

Precision Machined Contacts

NorComp’s machined MICRO-D connectors are designed for reliable mating performance and dependable signal integrity in demanding applications.

Metal Shell Construction

The rugged metal shell design helps support durability in environments involving vibration, movement, and repeated mating cycles.

Weight and Space Savings

Reducing connector size can help lower overall system weight while freeing valuable space for additional functionality.

Ideal for High-Performance Electronics

MICRO-D connectors are often selected when standard D-Sub interfaces are simply too large for the application.

The Backshell Matters Too

Compact systems also create cable management challenges.

NorComp MICRO-D backshells help provide:

Cable strain relief
Mechanical cable protection
Improved cable routing
Cleaner integration inside compact assemblies
Shielding support depending on configuration

Despite the added functionality, the backshell remains incredibly compact relative to the connector itself.

MICRO-D Shell Dimensions

NorComp MICRO-D Series Machined MICRO-D connectors are available in 9, 15, and 25 position configurations with compact metal shell construction designed for space-constrained applications.

Size	A	B	C
9 Position	19.93 mm	14.35 mm	7.8 mm
15 Position	23.75 mm	18.20 mm	7.8 mm
25 Position	30.10 mm	24.55 mm	7.8 mm

Common MICRO-D Applications

NorComp MICRO-D connectors are commonly used in:

Compact Without Compromise

Miniaturization often introduces tradeoffs in durability or reliability.

NorComp’s machined MICRO-D connector solutions help engineers reduce size while maintaining the rugged mechanical and electrical performance required in demanding applications.

Sometimes the easiest way to understand just how compact they are is simply seeing one beside a quarter.
