Triaxial cable
Earth shield via fitting (right)
or shield terminal (left).
Connecting the sensor cable to the junction box:
• Connect the sensor cable to the TNC socket.
Seal up connection
Accelerometers with a TNC socket (e.g. VIB 6.1xx) can be connected
to the junction box using a short, pre-assembled cable with TNC con-
nector and protective caps. Order information can be found in the
latest PRÜFTECHNIK Condition Monitoring sensor catalog, available
free of charge in the internet on www.pruftechnik.com.
RPM sensor, temperature probe: The open cable end must be crimped
with a TNC plug (e.g. VIB 93022).
Attach the required protective caps on both cable ends to seal the
cable-sensor interface:
- VIB 6.701, straight version
- VIB 6.711, angled version.

Shielding

The shield of the triaxial cable can be grounded in the fitting of the re-
spective housing when permitted and appropriate. In the MUXes with
stainless steel housing, the shield can also be placed on the internal
shield terminal.
Shielded cables must be used for the digital outputs.

Insulation

Ensure that the junction box VIB 6.770/13 and the MUXes are electri-
cally insulated when installed.
