EMC Concept
The outstanding noise immunity of the IDENTControl against emission and
immission is based on its consistent shielding design, which uses the principle of
the Faraday cage. Interference is caught in the shield and safely diverted via the
ground connections.
The cable shielding is used to discharge electromagnetic interference. When
shielding a cable, you must connect both sides of the shield to ground with low
resistance and low inductance.

Note!
If cables with double shields are used, e.g. wire mesh and metalized foil, the both
shields must be connected together, with low resistance, at the ends when
making up the cable.
Power supply cables are the source of much interference, e.g. from the supply
lines of 3-phase electric motors. For this reason, the parallel laying of power
supply cables with data and signal cables should be avoided, particularly in the
same cable duct.
Note!
The circuit ground is conductively connected to the housing of the write/read head
and to the protective ground. (Connection image
