Nicomatic outlines how the DMM series incorporates shielding functions into the connector architecture to protect sensitive signals from Electromagnetic Interference (EMI) where installation space is limited.
Nicomatic details two configurations for maintaining electrical continuity: the DSMM for front-panel grounding and the DBMM for 360° cable shielding.
DSMM Maintains Front-Panel Ground Continuity
Small gaps between a panel-mounted connector and the chassis can interrupt shielding continuity. The DSMM addresses this with an enlarged flange machined directly from the connector body, rather than using a separate component.
A pre-installed conductive O-ring complies with MIL-G-83528 standards. To help prevent corrosion between the connector and panel, the gasket is available in silicone or fluorosilicone filled with Copper/Silver or Aluminum/Silver.
The DSMM provides electromagnetic sealing across a temperature range of -55°C to +125°C.
DBMM Enables 360° Cable Shielding
For 360° shield termination, a separate backshell can increase the Z-axis dimension, making integration impossible in low-profile architectures.
The DBMM instead incorporates the rear termination function into the connector, combining the connector and rear cover in a single monobloc component. This enables 360° shielding termination directly on the connector body without increasing connector length through an added backshell.
The complete protection fits within a depth of 15 mm, while retaining the modularity of DMM arrangements for Signal, Power and Coax.
