Rugged, miniature connectors for mission-critical systems
LEMO introduces the OPTIMA D Series, a compact and rugged connector platform engineered for performance in the most demanding environments. Purpose-built for defence, aerospace and mission-critical systems, the new series combines miniaturised form factors with military-grade reliability.
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; and multiple configuration options - including high-speed (USB, Ethernet), multipole, and coaxial.
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.
The OPTIMA D Series is now available globally directly from LEMO and its network of authorised 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 defence, aerospace and tactical applications.
