4 Electrical connection
The following can be connected for measurement signal conditioning:

Carrier‐frequency amplifier

DC amplifier
designed for strain gauge measurement systems.
The transducers are supplied in the standard version with a 3m cable and
6‐pin Pancon connector in a six‐wire configuration.

Plug‐in contact 1 (white) = measurement signal (+)
Plug‐in contact 3 (black) = excitation voltage (-)
Plug‐in contact 6 (gray) = sense lead (-)
Plug‐in contact 4 (blue) = excitation voltage (+)
Plug‐in contact 5 (green) = sense lead (+)
Plug‐in contact 2 (red) = measurement signal (-)

Fig. 4.1: Connection with a 6‐wire cable (choice of lengths: 3m, 6m or 12m)
With this cable assignment, the output voltage at the measuring amplifier is
positive when the transducer is loaded (see Fig.3.1).
4.2 Connection with four‐wire configuration
When transducers with a six‐wire configuration are connected to amplifiers
with a four‐wire configuration, the sense leads of the transducer must be con­
nected to the corresponding supply leads: Identification (+) with (+) and identi­
fication (-) with (-), see Fig. 4.1. This measure also reduces the cable resist­
ance of the excitation voltage leads.
