The Modular Micro-Connector Built for Harsh Environments: DDM Connectors by Nicomatic

In today’s systems, whether in defence, space, avionics or industrial electronics, performance, reliability and adaptability are non-negotiable.

Designed specifically for harsh environments, our DMM (2mm pitch metal) connectors deliver on all fronts. Backed by full compliance with MIL-DTL-83513G, DMM connectors offer a modular, high-density interconnect solution that combines power, signal, and RF transmission in a single rugged package.

A DMM connector is a rugged, modular 2mm-pitch micro connector designed for harsh environments, combining high-power, high-frequency, and signal contacts in a compact, MIL-spec compliant format.

What Are DMM Connectors?

Nicomatic’s DMM series connectors are rectangular, micro-miniature metal connectors with a 2mm pitch, capable of supporting Low Frequency (LF), High Power (HP), and High Frequency (HF/Coax) contacts. This makes them ideal for compact systems where multiple performance requirements must be integrated in a single interface.

Built for vibration, shock, EMI protection and size constraints, DMM connectors are frequently used in applications such as:

• Satellite and launch vehicle electronics
• Rugged military communication systems
• UAV and airborne electronics
• Ground vehicle and naval platform controls
• Harsh industrial control units

Why Choose Nicomatic’s DMM Series?

True Modularity

The DMM range allows combinations of up to four rows of contacts, mixing signal, high-power (up to 20A), and coax (up to 30GHz) in a single connector footprint. This makes it one of the most versatile micro-connectors on the market today.

Whether you need 2 or 120 contacts, or a blend of signal and RF we ensure that our DMM delivers, while significantly reducing connector count and weight.

Built for Harsh Environments

The shell is machined from 6061 aluminium alloy and provides robust mechanical and electromagnetic shielding. Designed for high-vibration, high-shock environments, the connector offers integrated or separate backshells and is available in panel mount, flange, wire-to-board, board-to-board, and wire-to-wire formats.

With optional IP-rated sealing and panel integration, it’s a truly ruggedised solution.

Electromagnetic and Mechanical Protection

Signal integrity and reliability are protected by the connector’s mechanical design and EMI shielding. In defence and aerospace applications where signal noise or vibration can lead to mission failure, the DMM connector is engineered to provide stable, protected, and interference-free performance.

Custom-Built and Ready Fast

Like all of our solutions, the DMM is manufactured to order, tailored precisely to your project needs. With a 4-week standard lead time (part number dependent) and express options available, it offers rare speed in a highly customised connector.

And when you need support, 2D/3D drawings and IPC 620 Class 3 harnessing are available to streamline your integration process.

Designed for the Future of Electronics

With industries increasingly demanding smaller, faster, and more reliable connections, the DMM connector is a platform for innovation. Whether you’re transmitting power, data, or high-frequency RF, DMM supports your system’s need for performance, protection, and flexibility. 

Quick Answers: DMM FAQs

What contacts are available? DMM connectors can be configured with as few as 2 contacts and up to 120 contacts, arranged in 1 to 4 rows.

Can I include high-power or high-frequency contacts in my design? Yes, the DMM range supports both High Power (HP) and High Frequency (HF/Coax) contacts. Each special contact occupies the footprint of 4 low-frequency contacts, allowing you to mix and match according to your system’s needs.

Do you offer custom solutions for unique application requirements? Absolutely. We provide fully customisable DMM connectors, including IP-rated builds, panel integration and bespoke configurations tailored to your project.

How long is the standard lead time, and is express service available? Standard lead time is 4 weeks, depending on the part number. An express manufacturing and dispatch service is also available for select part numbers at an additional cost.

Are both straight and 90-degree options available? Yes, DMM connectors are offered in both straight and 90-degree versions to suit various mechanical layouts.

Can the connectors be surface-mounted? Yes, the straight version of the DMM connector is surface-mountable, offering further flexibility in PCB design.

Are DMM connectors MIL-Spec compliant? Yes, they are tested and compliant with MIL-DTL-83513G, ensuring performance in demanding military and aerospace environments.

What types of backshells are available? You can choose from integrated, split, and mono backshells to meet mechanical protection and strain relief requirements.

Does Nicomatic provide harnessing solutions? Yes, full IPC 620 Class 3 harnessing is available to complement your connector selection with high-reliability cable assemblies.

Can I request technical drawings? 2D and 3D CAD drawings are available upon request to support your design and integration process.

Are DMM connectors compliant with environmental and regulatory standards? Yes, they meet compliance requirements for RoHS, REACh, ITAR, California Proposition 65, CMRT, and Dual Use export classifications.
