Triaxial cable
Triaxial cables are used for the connection between the MUXs and
for the string line to the VIBRONET Signalmaster switch cabinet. In
an environment with electromagnetic interference, triaxial cables are
also recommended as sensor cables.
M12 cable glands
MUXs of the VIB 8.306 ... M20 series are equipped with M20 cable
glands, whose clamping area is sufficient for entering a triaxial cable
into the housing.
In the case of MUXs of the VIB 8.306 series, the M12 cable glands of
the sensor cables (Sensor 1 ... 9) may have to be replaced with a suit-
able reduction (M20 - M12).
• Open the cable gland and remove the sealing insert as needed.
• Enter the cable end into the housing. Apply a few drops of oil to
the cable sheath to facilitate entering.
• Strip the outer cable sheath using a suitable tool (e.g., cable strip-
per VIB 81053). Make sure that the length of the available, coaxial
cable end reaches the connecting terminal.
• Place the outer cable shield into the gland. If a grounding rail is
available, you can also ground the shield via this terminal strip.
• Tighten the cable gland.
If a M12-M20 reduction is used:
• Remove the available M12 cable gland.
• Install the M12-M20 reduction.
• Place two matching washers between reduction and M20 cable
gland.
