Harmonic Drive MES-6, MES-9 and MEH-9 Micro Encoders
Harmonic Drive MES-6, MES-9 and MEH-9 Micro Encoders
The Harmonic Drive MES and MEH micro encoders provide incremental A/B feedback and an index channel in a small shaft-mounted package. MES-6 is the ultra-micro version; size-9 MES and MEH configurations provide shaft and hollow-shaft choices. These are incremental sensors for integration into a motor or mechanism, not absolute encoders, servo drives or complete positioning axes.
Review Summary
Consider MES/MEH when a very small feedback package and a compatible incremental input suit the mechanism. Match the full shaft, resolution and output-circuit code. Mechanical speed, pulse frequency, electrical loading and homing strategy must all fit; a fine count scale alone does not establish measurement accuracy.
