6 EMC cable gland contact?
EMC cable gland:
Using EMC cable gland connect the cable screen and connector
housing provides greater screening attenuation (approx. 3.97:
EMC cable gland
with all-round
contact via circular
spring
PE contact:
In contrast, shielding effectiveness reduced when the cable screening is
connected the contact.
- Improved elimination the sheath current
- Interference currents not flow into the connector
Fig.
Reason:
- The screen braiding has opened weakening its effectiveness
- The interference currents the screening flow into the connector
^ Higher impact the signal integrity
.
Reason:
- All-round contact via circular spring, conical clamp etc. dB) than just
using contact termination.Hoods and Housings 63
