| The Model R137 optical incremental encoder is designed for industrial-grade applications requiring high resolution in a small package. Mechanical features are as follows: • 37 mm dia x 37 mm long body; shielded cable; sealed to IP66 (IP 64 at shaft exit). • 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 • Monolithic integrated ASIC for internally interpolated resolutions up to 57,600 cycles/rev (230,400 counts/rev) |
