●
Can only be used in conjunction with a connecting cable 6GT2091-4Lxxx.
●
Length: 2 m
Maximum cable length
The RF120C can be operated with every reader configuration with the maximum cable
length of 50 m. In some situations, longer connecting cables up to 1000 m are possible. The
current consumption of the connected reader must, however, be taken into account. You will
find further information in the relevant system manuals.
Do not connect more than 2 pieces of cable (3 pieces for MOBY U/D) together to form a
longer cable since this produces additional contact resistance.
