Absolute rotary encoder A19 & A20

opticalmagneticsolid-shaft

The A19 Series, manufactured by Gurley Precision Instrument, is a miniature single-turn absolute rotary encoder equipped with an opto/magnetic electronic technology. It has an aluminum housing diameter of 19 mm and stainless steel solid or blind hollow shaft diameter of 3-4 mm. This encoder is designed to provide digital feedback information for any position-sensing applications. The seriesA19 & A20are miniature single-turn absolute rotary encoders with optical electronic technology. This encoder is used in a wide variety of position-sensing applications for the measuring of angles and distances in very small envelopes, where high resolution is required.In addition, the encoder features:Industrial20 BitsMiniature High-Resolution Absolute Encoder Major Features and Advantages:hFaster and more accurate than any resolver-based system hUp to 20-bit resolution, SSI outputh-40C to +85C extended operating temperature availablehLED illumination for long life (>100,000 hours)hOptical Nonius principleh19-20mm diameter housingh3-4mm (0.125”) diameter steel solid or blind hollow shaftBiSS interface available - consult factory for details Mechanical SpecificationsMoment of InertiaStarting TorqueRadial Shaft LoadAxial Shaft LoadBearing ArrangementBearingsMeasuring Rotational ElementNon-Operating SlewShock 11 (ms)Vibration (55-2000Hz)SealingAccelerationMax.
