Modular Design - Big Performance
The model 7700 incremental and Virtual Absolute
rotary encoder is a compact, non-contact modular encoder with superior performance. Available in a number of resolutions and configurations, the model 7700 is easy to install and with the use of its optional commutation tracks, eliminates the need for hall effect feedback for brushless motors. Features common to both models include: LED illumination for long life (>100,000 hours) Single phase array Opto IC Square wave, TTL and CMOS compatible output, 10mA sink 2, 4, 6, or 8 motor pole pairs (optional) Incremental versions include : Resolutions up to 5000 cycles/rev (20,000 counts/rev, or 0.018/count)
o Standard zero index signal Virtual Absolute versions include: 4,096 words/turn (standard); up to 16,384 words/turn max. (optional) True absolute position (after standard initialization 3.52 ° ) Compact (1” x 2”) external patented decoding electronics (see VG datasheet) Natural binary byte-wide multiplexed parallel output Built-in error detection
