Gurley Series 9x20 Rotary Incremental Encoder Motion Type: Rotary Usage Grade: Industrial Output: Incremental Max Resolution: 144,000 counts/rev = 9 arcseconds High Performance - Industrial Ruggedness The Series 9x20 is a family of optical incremental encoders designed for industrialgrade applications that require high resolution and high accuracy. The Series 920 is available in two basic models and a variety of mechanical configurations. All 920s share these features: ! ! ! ! ! ! LED illumination for long life (100,000 hours) Differential photo-detectors for signal stability Single-board, surface-mount electronics for reliability RS-422 differential line driver output for noise immunity Zero index signal Sealed bearings for contamination resistance (ABEC 7 in solid shaft version; ABEC 5 in blind hollow shaft version). ! IP66 sealing for harsh environments (IP64 at the shaft exit) Model 9120: Resolutions up to 4500 cycles/rev (18,000 counts/rev); optional index formats; optional input voltage. Model 9220: Dual read heads for improved accuracy; monolithic integrated ASIC for internally interpolated resolutions up to 36,000 cycles/rev (144,000 counts/rev); watchdog circuit.

1. Total Optical Encoder Error is the algebraic sum of Instrument Error + Quadrature Error + Interpolation Error. Typically, these error sources sum to a value less than the theoretical maximum. Error is guaranteed at 20°C and is defined at the signal transitions. It does not include quantization error, which is ±1/2 quantum. ("Quantum" is the final resolution of the encoder, after user's 4X quadrature decode.) 2. Instrument Error is the sum of disc pattern errors, disc eccentricity, bearing runout and other mechanical imperfections within the encoder. This error tends to vary slowly around...

Specifications Input Power 9120: +5 VDC @75 mA max. Standard; +12 VDC and +15 VDC available 9220: +5 VDC @75 mA max. Output Device On all channels: EIA/RS-422 balanced differential line driver, protected to survive an extended-duration short circuit across its output. May be used single-ended for TTL-compatible inputs. Index Options 9120: Index is available in one of three formats: ungated full cycle wide ±180°elect; Half-cycle wide, gated with high state of B; or quarter-cycle wide, gated with high states of A and B. 9220: Index is quarter-cycle wide, gated with high states of A and B....

920S WITH BASE CODE E 920S WITH BASE CODE D FLEXIBLE COUPLINGS NOTE: 1 Flexible couplings are intended to absorb normal installation misalignments and run-outs in order to prevent undue loading of the encoder bearings. To realize all the accuracy inherent in the encoder, the user should minimize misalignments as much as possible. 2. Shaft coupling model number is SCA-04E-XXE or -XXM, where XX is taken from the DIA CODE table in the dimension drawings section Gurley Precision Instruments 514 Fulton Street Troy, NY 12180 U.S.A.
