EMC Performance Information
Please refer to the
Technical Specification
section of the product operation manual.
EMC Performance of Cables and Connectors
Snell 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 1694 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.
