The OPTIMA D Series sets a new benchmark in miniature connector design, combining high contact density with reduced size and weight. Its compact form makes it ideal for tightly integrated systems where every millimetre matters.

Supporting modern defence architectures, the D Series enables reliable connectivity in portable, airborne and embedded platforms, without compromising durability or performance.

Built for Mission-Critical & Harsh Environments

Engineered to perform in extreme conditions, the OPTIMA D Series ensures consistent operation across defence and industrial environments:

• IP68 sealing (up to 20m for 2 hours), even when unmated
• Tested to MIL-STD-810H for shock, vibration and environmental durability
• High resistance to dust, moisture, pressure and corrosion
• EMI/RFI shielding for dependable signal integrity in RF-dense environments

This makes it suitable for both defence systems and harsh industrial applications, including field-deployed electronics, robotics and advanced instrumentation.

Reliable Connectivity in High-Density Systems

Designed for precision and reliability, the D Series supports modern electronic systems requiring high-performance signal and power transmission:

• High contact density (up to 32 contacts in a compact footprint)
• Secure push-pull or break-away locking for operational flexibility
• 5-spur keying system for accurate blind mating
• Consistent performance in vibration-prone and high-stress environments

The result is reliable connectivity across long-life defence programs, with reduced maintenance and improved system integration.

Flexible Integration for Modern Platforms

The modular design of the OPTIMA D Series enables seamless integration into complex systems:

• Support for signal, power, coaxial, USB and Ethernet applications
• Multiple sizes and configurations for system flexibility
• Flush mounting options for streamlined enclosure design
• Uniform PCB height for simplified assembly and design consistency

This versatility allows engineers to design efficient, scalable interconnect solutions across a wide range of defence and industrial platforms.

Optimised for Defence & Tactical Applications

The OPTIMA D Series is ideally suited to:

• Soldier-worn systems (communications, imaging, sensors)
• UAVs and aerospace electronics
• Embedded defence systems and portable equipment
• High-performance industrial systems in harsh environments

Its non-reflective, corrosion-resistant finish and secure locking mechanisms ensure dependable performance in demanding operational conditions.
