Glenair Mighty Mouse Connectors – All You Need to Know in One Summary

Glenair’s Mighty Mouse connectors are the industry standard for reduced size and weight applications. At half the weight and size of the regular D38999 connector, the Mighty Mouse series makes it a perfect choice where weight and space constrains are of critical design importance.

Comparing the two series, the Mighty Mouse connectors have:

  • Higher contact density
  • Integration of banding platform on connector back end
  • Much smaller wire gauge – it can be as small as #30
  • Weight for a 55 pin contact crimp receptacle: 15g vs 34.6 g (D38999/24)
  • 67 insert arrangements

As one starts the design process, it is of crucial importance to understand the product capabilities and features. Mighty Mouse connector series offers:

  • 076 inch contact spacing
  • 12 shell sizes, fitting between 1 and 130 contacts
  • Aluminum shells
  • Beryllium copper retention clips
  • Integral shield banding porch or accessory threads
  • Environmental seals
  • #22 through #28 AWG wire
  • Rear-release crimp contacts

Mighty Mouse connectors are easily scalable and can meet the customers unique application design requirements, from cabling to high-speed, USB and RJ45 design requests. We are going to discuss each of these features in more details below.

Cabling Capability:

  • Polyurethane jacketing (LSZH) -30°C to + 105°C
  • Rubber jacketing (thermoplastic elastomer) -55°C to + 135°C
  • Nomex®-55°C to + 260°C
  • Halar®-73°C to + 150°C
  • Duralectric™ jacketing -65°C to 225°C
  • Custom overmolds
  • Custom bulk –anything from shielded twisted pairs, Coax, 50 ohm, 75 ohm, 100 ohm, mixed/color wire gages etc.

 

Mighty Mouse Series 80 High-Speed:

Features dominant electrical performance in protocol specific applications – eSATA and USB 2.0/3.0.

In addition, the high-speed version of Mighty Mouse connectors accept size #8 Quadrax and Twinax contacts for Ethernet or high frequency applications where the transmission of the data needs to be flawless. Often times, we see these types of products being used in military radios and soldier communication equipment.

SuperSeal – Micro USB:

SuperSeal connectors are ideal for applications where electromagnetic pulse (EMP) failure is not acceptable. They are commonly found in military and civil aerospace applications. The series features:

  • Mated IP68 sealing
  • MicroAB and MicroB Interface
  • Feedthru or crimp removable contacts

In addition to Micro USB, Superseal USB type A features even more advanced technology more suitable for harsh applications. USB Type A can withstand rugged shock and vibration force as well as high operating temperatures. It is most commonly found in rugged military applications where quick data transfer is needed.

To wrap up, Mighty Mouse connectors are commonly used in military communication systems, aviation command and control units, soldier vests, fuel batteries, military drones and UAVs, military ground vehicles and store management systems.

As far as the benefits over other connector families go, Mighty Mouser Series 80 connectors are half the size and weight of D38999 connectors. Also, by featuring integrated back porch, this connector series eliminates any need for a backshell. It features high-speed and hermetic capabilities as described in the sections above. Lastly, it can easily be modified and integrated for cable assemblies as well as offered in RoHS compliant plating.

If you as a procurement manager or an engineer are not familiar with Mighty Mouse connectors, even after reading this article, here are some competitive lines Mighty Mouse Series 80 competes with:

Amphenol – 2M Series

Cannon – MKJ

Deutsch – Wildcat
