Rugged miniature series of connectors for mission-critical systems released

LEMO has introduced 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 demands of tactical communications, UAVs, avionics, and soldier-worn equipment, the 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 five-way keying - to support rapid deployment and error-free connections
• Multiple configuration options - including high-speed (USB, Ethernet), multipole, and coaxial

With a compact, overmoulded design that's 25% shorter than the company's standard connectors, the series allows 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 producing compact, durable platforms.

To support rapid and secure integration, the company offers full cable assembly services:

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