EMC Performance of Cables and Connectors
Snell & Wilcox products are designed to meet or exceed the requirements of the appropriate European EMC
standards. In order to achieve this performance in real installations it is essential to use cables and connectors
with good EMC characteristics.
All signal connections (including remote control connections) shall be made with screened cables terminated in
connectors having a metal shell. The cable screen shall have a large-area contact with the metal shell.
COAXIAL CABLES
Coaxial cables connections (particularly serial digital video connections) shall be made with high-quality
double-screened coaxial cables such as Belden 8281 or BBC type PSF1/2M.
D-TYPE CONNECTORS
D-type connectors shall have metal shells making good RF contact with the cable screen. Connectors having
"dimples" which improve the contact between the plug and socket shells, are recommended.
