The type T32 FN / T32 FNA torque transducers differ only in the type of con-
nector:
T32FN
MS 3102A16S--1P
. . . . . . . . . . . .
T32FNA
Binder 423
. . . . . . . . . . .
The two 7-pole instrument plugs Binder 423 (MS 3102 A 1 6S--1 P for
T32 FN) mounted at the housing are marked ”MD” for the torque signal and
”n” for the speed signal.

The lead screen is laid flat on the connector case. This means that the com-
plete measurement system is enclosed in a Faraday cage, reducing any elec-
tromagnetic interference.
With interference caused by potential differences (equalisation currents) the
system zero-voltage and the housing ground should be isolated from one
another and a potential equalisation conductor located between the housings
of the transducer and the amplifier (flexible stranded wire, 10 mm
2
conductor
cross-section).
