1 F , May 2017 F-60-2 bsolute position, rotary lectric ncoder The F-60 is a member of the F series of lectric ncoders, based on Netzer Precision proprietary technology. The lectric ncoder offers many advantages - some unparalleled Low profile (10 mm). Hollow, floating shaft. No bearings or other contacting elements. High resolution and precision. High tolerance to temperature extremes, shock, moisture, MI, RFI and Magnetic fields. Very low weight. Holistic signal generation igital interfaces. Mechanical llowable mounting eccentricity llowable rotor axial motion ±0.1 mm ±0.1 mm Rotor inertia 8,669 gr mm 2 Total weight Outer Ø /Inner Ø/ Height Material (stator, rotor) Nominal air gap (stator, rotor) 8 gr 60/ 27 / 10 mm luminum 0.6 mm The lectric ncoder 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 lectric ncoder 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 lectric ncoder virtually failure free. The internally shielded, operated lectric ncoder includes an electric field generator, a field receiver, a sinusoidal shaped dielectric rotor, and processing electronics. The output of lectric ncoder 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. lectrical Supply voltage ± 5% Interconnection able Length Shielded cable or 1,500 mm MX nvironmental M I , I Operating temperature range Storage temperature Relative humidity Shock endurance Vibration endurance Protection IP to to % Non condensing 100 g for 11 ms 20 g Hz haracteristics ngular resolution Static error Maximum operational speed Measurement range uild In Test IT 18 bits ; 262,144 PR < 10 meg 750 rpm Unlimited rotation Optional 1
