Motor Mount Incremental Encoders For stepper motor or servo motor control, motor mount encoders install easily without adaptors or extra hardware for fast, simple direct to motor installation (or mounting to other free shafts). Available in commercial, industrial-duty and commutation motor versions.  Choose from ring-mount, hubshaft or hollowshaft mounting configurations.  Our motor mount encoders provide reliable feedback for servo and stepper motor applications, even high speed motors up to 12000 RPM.  Ruggedized versions with unbreakable metal disks are available for harsh environments or heat up to 120°C.  Commutation encoders apply optional 3 phase communication tracks to replace traditional Hall Effect sensors.
