Glenair Micro-D Connectors: M83513 Metal Shell Connector Solutions

Glenair Micro-D connectors are widely used in high-reliability interconnect systems where compact size, low weight and dependable electrical performance are required. Designed for demanding aerospace, defense, space, industrial and electronic equipment applications, Glenair Micro-D connectors provide a high-density rectangular connector solution in a miniature package.

Glenair’s Micro-D connector family includes MIL-DTL-83513 QPL and commercial Micro-D products. According to Glenair, these connectors use high-density micro TwistPin contacts on .050 inch centers and are available in contact arrangements from 9 to 130 contacts, with insulated wire, uninsulated wire, PCB, solder cup and flex termination options.

What Are M83513 Micro-D Connectors?

M83513 Micro-D connectors are miniature rectangular connectors designed for high-performance signal transmission in compact electronic systems. Compared with standard D-subminiature connectors, Micro-D connectors offer a smaller footprint and higher contact density, making them suitable for applications where board space, panel space and cable weight are limited.

Glenair provides M83513 Micro-D connectors in solder cup, pre-wired and PCB versions, and its M83513 connectors use TwistPin contacts for high-performance applications. Metal shell versions are especially suitable for rugged environments where mechanical durability, shielding performance and reliable mating are important.

Glenair’s metal shell Micro-D connector and pigtail product group includes series such as GMDE, GMDR, GMLM, GRPM, GSWM and MWDM, covering solder cup connectors, insulated wire pigtails, uninsulated wire pigtails, back-to-back cable assemblies, shielded cable assemblies, right-angle exits, environmentally sealed designs and SpaceWire cable assemblies.

Glenair MWDM Metal Shell Micro-D Connectors

The Glenair MWDM series is one of the most commonly referenced metal shell Micro-D connector families. It is available in solder cup, insulated wire pigtail, uninsulated wire pigtail, shielded cable assembly and back-to-back cable assembly versions.

MWDM solder cup Micro-D connectors feature gold-plated TwistPin contacts and are designed for wire termination applications. Glenair also notes availability of 24 AWG contact options for certain solder cup configurations, providing increased mechanical strength and lower voltage drop compared with smaller wire sizes.

For harness applications, MWDM insulated wire pigtail connectors are supplied with gold-plated TwistPin contacts and mil-spec crimp termination. These pre-wired connectors are tested and backpotted, helping reduce assembly work during cable harness manufacturing.

Available Connector Configurations

Glenair Micro-D M83513 metal shell connectors can be selected according to the mechanical design, termination method and environmental requirements of the application.

Electrical and Mechanical Performance

Glenair’s Micro-D performance specifications describe MWDM metal shell and MWDL plastic shell Micro-D connectors with TwistPin contacts on .050 inch centers. The specification lists requirements such as 5,000 megohms minimum insulation resistance, 600 VAC dielectric withstanding voltage at sea level, 3.0 ampere continuous-duty contact current capability from -55°C to +150°C, and 500 mating cycles durability.

For metal shell Micro-D connectors, Glenair also specifies shielding-related performance when optional grounding springs are used, including shell-to-shell conductivity and shielding effectiveness requirements. This makes metal shell Micro-D connectors a practical choice for systems where signal integrity, grounding and EMI control are important design considerations.

In these applications, engineers often choose Micro-D connectors when they need reliable multi-contact signal transmission in limited space while maintaining strong mechanical performance.

How to Select Glenair Micro-D Connectors

When selecting a Glenair Micro-D connector, the following factors should be reviewed:

1. Contact Count

Choose the required contact arrangement based on signal quantity and system layout. Glenair Micro-D connectors are available in multiple arrangements from low pin counts to high-density configurations.

2. Shell Type and Finish

Metal shell connectors can support rugged mechanical requirements and shielding needs. Shell material and finish should be selected according to corrosion resistance, conductivity and application environment.

3. Termination Style

Solder cup connectors are suitable for flexible wiring and repair work. Pre-wired pigtail versions help simplify harness assembly. PCB versions are suitable for board-level connection.

4. Wire Type and Gauge

For pigtail and cable assembly versions, wire type, wire gauge, insulation material and wire length should match the electrical and environmental requirements of the project.

5. Mounting and Hardware

Panel mounting, jackscrews, jackposts and rear panel mounting options should be selected according to equipment structure and maintenance requirements.

6. Environmental Requirements

For harsh environments, sealed or shielded Micro-D connector options may be required. GMDE environmentally sealed Micro-D connectors, for example, are designed with O-ring sealing and epoxy wire sealing for immersion requirements.
