The Models R119 and R120 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
• Represent 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 16,384 cycles/rev (65,536 counts/rev)

R119: f19-mm body; ribbon cable

R120: f20-mm body; round cable with shielded twisted pairs
