EMI AND SIGNAL NOISE
MANAGEMENT IN MINIATURE
CONNECTOR AND CABLE SYSTEMS
By Bob Stanton, Director of Technology, Omnetics (www.omnetics.com)
	 Electronic interconnection designs
for defense electronics, highly mobile
robots, surgical monitoring devices and
other embedded systems are rapidly
changing. Signal speeds are increasing,
and are often crammed into smaller and
tighter spaces, and potential signal interference as well as crosstalk can become
a technical issue. Instrument-level connections must contribute to ensuring

electromagnetic compatibility (EMC), is
achieved.
EMC standards specify four levels.
Level 1 includes discrete components,
Level 2 is focused on circuit boards, OEM
electronic products are addressed at
Level 3, which includes electronic circuitry, power sources, motherboards,
and interconnect systems. Cables extending beyond the enclosure should

comply to Level 4, depending on the
application.
The interconnect designer's goal is also
to contain any potential electromagnetic
interference (EMI) that would confuse the
main signal system. Connector and cable
shielding is used to attenuate the radiation signals from entering the interconnection, as it bleeds off any conducted
noise running on the shielding. Selecting
