Size, Weight and Performance Optimization: A Monobloc Connector for High-Performance EMC Shielding

Protecting sensitive signals against electromagnetic interference (EMI) is a physical challenge, especially when space is limited. Standard solutions often force a difficult compromise: ensure effective shielding or save valuable space.

To reconcile signal integrity with high density, the DMM series now integrates shielding functions directly into the product architecture. This approach resolves a major physical contradiction: adding external protections (backshells, additional gaskets) mechanically degrades the SWaP (Size, Weight and Power) ratio.

Rather than stacking multiple interfaces ,which become RF leakage paths and potential failure points under vibration, this integrated design eliminates weak links, ensuring shielding continuity without impacting available volume.

Here are the two technical configurations designed to guarantee perfect electrical continuity:

1. Front Panel Ground Continuity: The DSMM

In a conventional panel-mounted assembly, micro-gaps between the connector and the chassis create shielding discontinuities.

The DSMM eliminates RF leakage by ensuring perfect electrical continuity across the entire contact surface.

• Mechanical Design: The DSMM integrates an enlarged flange machined directly from the connector body. This is not an added component, ensuring maximum mechanical robustness.
• Key Specification (EMI Gasket): Delivered with a pre-installed conductive O-ring compliant with MIL-G-83528 standards.
• Galvanic Optimization: To prevent corrosion between the connector and your panel, the gasket is available in four material options: Silicone or Fluorosilicone filled with Copper/Silver or Aluminum/Silver.
• Performance: This design ensuring perfect electromagnetic sealing from 55°C to +125°C.

2. 360° Cable Shielding: The DBMM

Achieving a full 360° shielding termination using an added accessory (backshell) significantly penalizes the Z-axis, making integration impossible in low-profile architectures.

The DBMM overcomes this geometric constraint by internalizing the rear termination function, allowing signal shielding without increasing connector length.

Mechanical Design: The DBMM merges the connector and rear cover into a single monobloc component. Key Specification: Enables 360° shielding termination directly on the connector body. SWaP Advantage: This complete protection fits within a record depth of 15 mm. You retain the full modularity of DMM arrangements (Signal, Power, Coax) without the added bulk of a backshell.
