Generic Shielded Cable Description
MKS offers a full line of cables for all MKS equipment. Should you choose to manufacture your own
cables, follow the guidelines listed below:
1. The cable must have a braided shield, covering all wires. Neither aluminum foil nor spiral
shielding will be as effective; using either may nullify regulatory compliance.
2. The connectors must have a metal case which has direct contact to the cable’s shield on the
whole circumference of the cable. The inductance of a flying lead or wire from the shield to the
connector will seriously degrade the shield’s effectiveness. The shield should be grounded to
the connector before its internal wires exit.
3. With very few exceptions, the connector(s) must make good contact to the device’s case
(ground). “Good contact” is about 0.01 ohms; and the ground should surround all wires.
Contact to ground at just one point may not suffice.
