Allocation of the cable cores

The KMR connection cable has colour‐coded free ends.
It is 1.5 m long. With amplifiers with connection sockets,
you first have to solder a plug onto the cable. The cable
screen (ye) is not connected to the transducer ground. It
has to be connected to the amplifier's operating voltage
zero (contact 12, E, 1).
If the transducer is connected according to the
indications given in the table, the output voltage at the
amplifier is positive when the transducer is charged in the
indicated direction of force. If with compressive
transducer forces a negative output voltage at the
amplifier is required, simply interchange the white and
red cable cores.
The pin assignment for some of the HBM amplifiers can
be taken from the following table or you can refer to the
respective operating manual for your amplifier.
