Electrical connection

3.1 General information

To make the electrical connection between the torque transducer and the
amplifier, we recommend using shielded, low‐capacitance measurement
cables from HBM.
With cable extensions, make sure that there is a proper connection with
minimum contact resistance and good insulation. All plug connections or swivel
nuts nuts must be fully tightened.
Do not route the measurement cables parallel to power lines and control
circuits. If this cannot be avoided (in cable pits, for example), maintain a
minimum distance of 50 cm and also draw the measurement cable into a steel
tube.
Avoid transformers, motors, contactors, thyristor controls and similar stray‐field
sources.

3.2 Connector plug

The transducer is equipped with a permanently mounted housing plug.
It can be connected to the applicable measurement electronics via the
transducer connection cable (accessories, see Page 19). The pin assignments
for the transducer connection cable can be found in the following table:
