Miniature incremental rotary encoder
32 000 counts/rev | R112 GURLEY Precision Instruments

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:
- 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 8,000
- cycles/rev (32,000 counts/rev)
