HTT-20 & HMT-20 Brushless
Multi-turn Resolver Transducers |
FEATURES: |
|
- 5 different vernier encoded multi-turn configurations
- best angular accuracy and repeatability
- ideal for high-shock applications
- internally geared housing for reliability
- 100% compatible with AMCI's complete line of resolver
interface products
|
DESCRIPTION |
|
 Many
applications require high-resolution, multi-turn position
sensing. In response to market demands, AMCI engineered the
HTT/HMT-20 series of resolver transducers
to provide absolute position feedback with up to 1,800 turns
and a maximum resolution up to 4096 counts/turn (module dependent).
The HTT-20-1 is for redundant single-turn applications.
Using an internally geared housing ensures reliable operation
in a space saving compact design. This resolver transducer
has a 5/8" keyed shaft, 1/4" X 20 mounting holes,
sealed bearings, mil-spec connector, and is sealed for a IP64
rating.
