ELECTRICAL CONNECTION
8.1
Connection to a measuring amplifier without an integrated amplifier
The C2 is a force transducer that outputs a mV/V signal based on strain gages. An ampli
fier is needed to condition the signal. Any DC amplifiers and carrier-frequency amplifiers
designed for strain gage measuring systems can be used.
Force transducers are executed in a 6-wire configuration.

General connection information
Fig. 8.1
6-wire connection without plug
With this pin assignment, the output signal is positive under compressive load. If you
need a negative output signal in the pressure direction, exchange the red and white wires
at your amplifier input.
The connection cable shield is connected to the transducer housing. If you are not using
pre-wired HBK cables, connect the cable shield to the cable socket housing. Use shielded
plugs on the open ends of the cable to be connected to the amplifier system, with the
shielding extensively applied. With other connection techniques, a good EMC shield must
be provided in the stranded area, where the shielding must also be extensively con
nected.
8.1.2
Connection to an M12 male connector without integrated amplifier
The C2 can be purchased with a built-in M12 plug but without an integrated amplifier.
In this case, the pin assignment of the sensor changes (see Tab. 8.1
"Pin assignment with M12 male connector - without integrated amplifier").
