Gurley Model R112 Rotary Incremental Mini-Encoder - 1

Gurley Model R112 Rotary Incremental Mini-Encoder Motion Type: Rotary Usage Grade: Light Industrial Output: Incremental Max Resolution: 32,000 counts/rev Miniature High-Resolution Encoder The Models R112S and R112B optical incremental encoders are designed for light industrial applications that require high resolution in a very small package. The two models share these features: -40C to +85C extended operating temperature available Either shafted or blind-hollow shaft version 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 Monolithic integrated ASIC for internally interpolated resolutions up to 32,000 counts/rev R112S and R112B: f12-mm body; ribbon cable.

Gurley Model R112 Rotary Incremental Mini-Encoder - 3

Specifications INPUT POWER +5 VDC ±0.25 V @100 mA max. SQUARE WAVE OUTPUT Quadrature square waves at 1, 2, 3, 4, 5, 8, 10, 12 or 16 times the line count on the disc. 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 is ¼-cycle wide, gated with the high states of channels A and B. OUTPUT WAVEFORMS (CW rotation shown) CHANNEL A CHANNEL / A CHANNEL B CHANNEL / B INDEX ELECTRICAL CONNECTIONS Output Functions A /A B /B IND / IND +V COMMON Not Used...
