ABSOLUTE POSITION ROTARY ELECTRIC ENCODER HARSH ENVIRONMENT The DS-25 is a member of the DS series of Electric Encoders™ a product line based on Netzer Precision Position Sensor proprietary technology. EE products are characterized by features that enable unparalleled performance: DATA SHEET The Electric Encoder™ is unique in being holistic, i.e., its output reading is the averaged outcome of the whole area of the rotor, This feature makes the Electric Encoder™ forgiving to mounting tolerances, mechanical wander etc. The absence of components such as ball bearings, flexible couplers, glass disc, light sources and detectors, along with very low power consumption makes the Electric Encoder™ virtually failure free. • Hollow, floating shaft • No bearings or other contact elements • High resolution and unparalleled precision • High tolerance to temperature extremes, shock, moisture, EMI, RFI and magnetic fields • Very low weight • Holistic signal generation • Digital interfaces for absolute position The internally shielded, DC operated Electric Encoder™ includes an electric field generator, a field receiver, a sinusoidal shaped dielectric rotor, and processing electronics. The output of Electric Encoder™ is a digital serial with absolute position single turn. The combination of precision, low profile, low weight and high reliability have made Netzer Precision encoders particularly suitable to a wide variety of industrial automation applications.

ABSOLUTE POSITION ROTARY ELECTRIC ENCODER HARSH ENVIRONMENT Digital SSi Interface Synchronous Serial Interface (SSi) is a point to point serial interface standard between a master (e.g. controller) and a slave (e.g. sensor) for digital data transmission. SSi / BiSS output signal parameters Serial output Clock Frequency Position update rate SSi / BiSS interface wires color code Encoder Data Green Black BiSS – C Interface is unidirectional serial synchronous protocol for digital data transmission where the Encoder acts as “slave” transmits data according to “Master” clock.
