LEMO, a global leader in precision connector solutions, has unveiled its latest innovation: the OPTIMA D Series. Designed for the most demanding environments, this new range of compact, rugged connectors is purpose-built for defense, aerospace, and tactical systems where reliability, space efficiency, and performance are paramount.
Key Features of the OPTIMA D Series

- Miniature & Compact Design: The overmolded plug is 25% shorter than standard LEMO connectors, making it ideal for space-constrained applications.
- High Contact Density: Supports up to 32 contacts in a compact form factor.
- IP68 Sealing: Offers water and dust protection even when unmated (20m for 2 hours).
- MIL-STD-810H Compliance: Tested for shock, vibration, and extreme environmental conditions.
- Modular Architecture: Available in five sizes with multiple configurations including:
- High-speed data (USB, Ethernet)
- Multipole power/signal
- Coaxial solutions
- Secure Mating Systems: Choose between Push-Pull or Break-Away latching mechanisms, both featuring robust 5-spur keying for blind mating.
- EMI/RFI Shielding: Ensures clean signal transmission in noisy environments.
- Durability: Rated for over 5,000 mating cycles.
Applications & Use Cases
The OPTIMA D Series is engineered to meet the evolving needs of modern mission-critical systems. Its versatility and ruggedness make it suitable for:
- Defense & Tactical Gear: Soldier-worn devices such as radios, headsets, and visual enhancement systems.
- Aerospace & UAVs: Ideal for avionics, drones, and onboard systems requiring compact, vibration-resistant connectors.
