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.

PRODUCT OVERVIEW U M 3.2 I 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.
