SAFETY
2.1 S
2.2 ESD
The DF-60 Electric Encoder is insensi ve to ESD and parasi c
capaci ve coupling from adjacent AC voltages. It is highly
recommended to enable discharge path with less than several
tens of kΩ between the machine sha and the electronics
ground.
Shielding: the Electric Encoder housing is built of Aluminum
with non-conduc ve anodized layer.
The internal ground (return) path of the 5V power supply
IS NOT CONNECTED to the cable shielding, it is highly
recommended to ground the cable shielding through the
connector buddy or by other means.
Note : During high speed rotaƟon, bearings may isolate the
shaŌ from its grounding. The shaŌ must be grounded using a
sustainable method for the operaƟon rotaƟon speed.

3.1 O
The DF-60-32-SG-S0 absolute posi on Electric Encoder™ is a
revolu onary posi on sensor , originally developed for harsh
environment specialized applica ons, available for broader
range of defense, homeland security, aerospace and industrial
automa on.
The Electric Encoder™ non-contact technology relies on
interac on between the measured displacement and a space/
me modulated electric field.
The DF-60 Electric Encoder™ is modular, i.e. its rotor and stator
are separate.
