LEMO introduces the OPTIMA D Series, a compact and rugged connector platform engineered for performance in the most demanding environments. Purpose-built for defense, aerospace, and mission-critical systems, the new series combines miniaturized form factors with military-grade reliability.

Key features: rugged, compact, and configurable
Engineered to meet the evolving needs of tactical communications, UAVs, avionics, and soldier-worn equipment, the OPTIMA D Series offers:

  • IP68 sealing (20m/2h) – even when unmated
  • MIL-STD-810H compliance – resistant to shock, vibration, and extreme environmental stress
  • Push-Pull and Break-Away latching – for secure, blind mating in high-pressure scenarios
  • Modular design with robust 5-way keying – to support rapid deployment and error-free connections
  • Multiple configuration options – including high-speed (USB, Ethernet), multipole, and coaxial 

Optimized for integration
With a compact, overmolded design that’s 25% shorter than standard LEMO connectors, the OPTIMA D Series enables space-constrained integration without compromising signal integrity or ruggedness.
Its uniform PCB height and flush-mounting options streamline system architecture, making it a go-to choice for OEMs developing compact, durable platforms.

End-to-end cable assembly services
To support rapid and secure integration, LEMO offers full cable assembly services:

  • Custom overmolding
  • Complex harness design
  • Private labeling
  • Certified production: IPC-620, ISO 9001, AS9100, and MIL-STD-810

The OPTIMA D Series is now available globally directly from LEMO and its network of authorized distributors and partners. Whether for new designs or system upgrades, this next-generation solution is ready to meet the demands of today’s most challenging defense, aerospace, and tactical applications.
