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
