Connection
Connect the read/write head to the IDENTControl interface using a shielded
connection cable (see chapter 4.6.2). Make sure that the shielding is continuous
to prevent EMC interference. (see chapter 5.5)
5.5
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.
write head
The screening of cables provides for the discharge of electromagnetic
interference. When screening a cable, both sides of the screen must be
connected to the earth 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.
The metal enclosure of the IDENTControl and the metal enclosure of the R/W
heads complete the consistent shielding concept.
