Miniature Form. Maximum Function — Mighty Mouse Connector Series 80
When space is tight and reliability is non-negotiable, engineers reach for the Series 80 Mighty Mouse Connector — a miniature circular connector that delivers heavyweight performance.
Roughly half the size and weight of traditional MIL-DTL-38999 connectors, it offers IP67+ sealing, 360° EMI protection, and up to 10,000 mating cycles in aerospace, defense, robotics, and industrial environments.
Optimized for Harsh Environments
XACT EMS integrates these connectors into custom overmolded cable assemblies built for mission-critical platforms where SWaP (Size, Weight & Power) optimization matters most. As a result, these assemblies deliver reliable connectivity even in high-vibration, high-temperature, or high-moisture conditions.
Why It Earned the Name “Mighty.”
| Feature | Performance Advantage |
|---|---|
| Size & Weight | ~50% smaller and lighter than MIL-DTL-38999 connectors |
| Environmental Sealing | IP67 – IP69 dust and moisture protection |
| EMI/RFI Shielding | 360° coverage for signal integrity |
| Durability | 500 – 10,000 mating cycles tested |
| Materials | Aluminum, stainless steel, or composite shells |
| Coupling Styles | Threaded, bayonet, push-pull |
| Temperature Range | −55 °C to +150 °C |
| Standards | MIL-STD-810 & RTCA DO-160 environmental testing |
Additionally, XACT builds to spec — not stock. Every assembly undergoes AS9100-certified inspection and traceable testing for regulated industries.
Applications That Rely on It
| Industry | Example Systems |
|---|---|
| Defense & Military | Soldier-worn radios, targeting systems, UAV payloads |
| Aerospace | Avionics modules, cockpit controls, navigation units |
| Robotics | Autonomous ground vehicles, sensor arrays |
| Energy & Industrial | Downhole inspection tools, portable instrumentation |
| Medical & Emergency | Ruggedized wearables and field equipment |
