DBK41/CE
The DBK41/CE includes 3 variations of EMI shield plates that attach to the DBK41 enclosure. Besides
acting as an electrical safety barrier, these shields reduce electromagnetic interference (EMI).
Note : The CE kit is included with the DBK41/CE. It can be purchased as an optional accessory for use
with DBK41.
BNC Connectors for CE Compliance
Exposed BNC connectors can receive static charges, which can enter the board’s circuitry, resulting in
ESD damage. To comply with CE standards, BNC connectors must be shielded from high-voltage sources
such as static charges.
Some points:
•
Cable and connector requirements are stated in the product’s Declaration of Conformity .
These are typically special coaxial cables with insulated end-connectors and rubber O-rings,
for example, cable kit p/n 418-0800.
•
PVC dust caps (p/n CN-96) must cover all unused BNC connectors.
•
Properly installed connectors and dust caps will cover the entire surface of the BNC, i.e., no
BNC metal will be exposed.
