CMA LD

High contact density in a robust and ergonomic connector

36 contacts, IP68, push-pull

• HIGH DENSITY
• ROBUSTNESS
• EMC REINFORCEMENT

The CMA LD delivers high contact density in a compact, ruggedized push-pull connector. With 36 contacts, a stainless steel shell, IP68 sealing, and reinforced EMI/RFI shielding, it addresses applications requiring dense signal integration in limited space — a key requirement for modern defense electronics, C4ISR systems, and embedded avionics.

36 contacts in a compact, shielded connector for high-density integration

Where standard connectors reach their limits in terms of contact count within a small footprint, the CMA LD provides 36 contacts in a push-pull circular form factor. Its stainless steel shell — with marine stainless steel and marine bronze options — ensures corrosion resistance in harsh field environments, while EMC reinforcement maintains signal integrity across all contacts.
