This state-of-the-art encoder technology offers many features, some unparalleled: • Hollow floating shaft • No bearing or other contact • High precision. • High tolerance to temperature, shock, moisture, EMI, RFI and magnetic fields. • Multiple protocol interface • Continues output Demanding application suited to the DS-247-128 include: Aerospace, medical, instrumentation, automation, etc. (i) | | | | | | The holistic structure of the Electric Encoder™ provides generous mounting tolerance, thus obviating the need for internal ball bearings. The absence of ball bearings and components such as flexible couplers, glass disc, light sources and detectors, along with very low power consumption makes the DS-247 encoder virtually failure free. The internally shielded, DC operated DS-247 includes an electric field generator, a field receiver, a sinusoidal-shaped dielectric rotor, and processing electronics. | | | | | | | | | | | | | | | | | | | (2) Allowable mounting eccentricity | ±0.2 mm | | | | (2) Allowable rotor axial motion | ±0.1 mm | | | | Rotor inertia | | 158.434 gr-mm2 | | | | Total weight | 665 gr | | | | Outer diameter / Inner diameter / | 247.6 / 170.2 / 18 mm | | | | profile | | | | | Material (stator, rotor) | Aluminum , llltem™ | | | | | | | | Electrical | | | | | Supply voltage | | (3) +4.6to +5.5V | | | | Supply current | (4) ~ 10 mA | | | | Maximum load current | | 5 mA | | | | Output resistance | <1Q | | | | Servo bandwidth | | DC to 1 kHz | | | | | | 6 pins connector + | | | | Interconnection | 25 cm Teflon-coated, | | | | | | AWG-32 wires | | | | Environment | | | | | (5) EMC | IEC6100-6-2, IEC6100-6-4 | | | | Operating temperature range | (6) -55°Cto+125 °C | | | | Relative humidity | <98 % non condensing | | | | Shock endurance | IEC 60068-2-27 ; 100gfor 11 ms | | | | Vibration endurance | | IEC 60068-2-6; 20g 10-2000 Hz | | | | (7) Protection | IP40 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
