The Models and optical incremental encoders are designed for light industrial
applications that require high resolution in a very small package. The two models share these
features:
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)
SQUARE WAVE OUTPUT
Quadrature square waves at 1, 2, 5, 10, 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.
SPECIALCAPABILITIES
For special situations, we can optimize catalog encoders to provide higher frequency response, greater accuracy, wider
temperature range, reduced torque, non-standard line counts, or other modified characteristics. In addition, we regularly
design and manufacture custom encoders for user-specific requirements. These range from high-volume, low-cost, limitedperformance
commercial applications to encoders for military, aerospace and similar high-performance, high-reliability
conditions.We would welcome the opportunity to help you with your encoder needs.
