DS-130-datasheet-V2.2 , AUG 2015 DS-130 Absolute position, rotary Electric Encoder™ The DS-130 is a member of the DS series of Electric Encoders™, based on Netzer Precision proprietary technology. The Electric Encoder™ offers many advantages - some unparalleled Low profile (10mm). Hollow, floating shaft. No bearings or other contacting elements. High resolution and precision. High tolerance to temperature extremes , shock, moisture, EMI, RFI and Magnetic fields. Very low weight. Holistic signal generation Absolute Position over digital interfaces. Mechanical Allowable mounting eccentricity Allowable rotor axial motion Rotor inertia Total weight Outer Ø /Inner Ø/ Height Material (stator, rotor) ±0.1 mm ±0.1 mm 12.378 gr · mm2 65 gr 130 / 90 / 10 mm Ultem™ polymer Electrical Supply voltage Interconnection Cable Length Environmental EMC Operating temperature range Relative humidity Shock endurance Vibration endurance Protection 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. 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 signals of Electric Encoder™ are analog Sine / Cosine representing the rotation angle. The digital outputs are obtained by further processing - which may be either internal or external to the encoder. The combination of precision, low profile, low weight and high reliability have made Netzer Precision encoders particularly suitable to a wide variety of critical applications including, but not limited to medical equipment and aerospace. 5V ± 5% Shielded cable or 1,500 mm MAX IEC 6100-6-2, IEC 6100-6-4 Digital: -40°C to +85°C 98% Non condensing 100 g for 11 ms 20 g 10 – 2000 Hz IP 40 Characteristics Angular resolution Static error Maximum operational speed Measurement range Power On - Max. operational speed Build In Test BIT www.netzerprecision.com 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, ball bearing wander etc. 19 bits ; 524,288 CPR < 10 mDeg 750 rpm Unlimited rotation 3.3 RPM , <=20°/sec Optional 1 DS-130-datasheet-V2.2 , AUG 2015 DS-130 Absolute position, rotary Electric Encoder™ 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.
