HTT-20 Brushless Multi-turn Resolver Transducers


FEATURES:
  • 4 different vernier encoded multi-turn configurations
  • best angular accuracy and repeatability
  • IP64 rated
  • 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-20 series of IP64 rated resolver transducers to provide absolute position feedback for up to 1,800 turns with a maximum resolution up to 4,096 counts/turn. The actual number of counts per turn depends on the transducer and the electronics used to decode the position.

Each transducer contains two resolvers that are geared together in a vernier arrangement. For the 100 turn and 180 turn transducers, this arrangement requires only two gears. This mechanical simplicity makes the HTT-20 transducers more reliable then transducers that have a multi-pass gear train between the two resolvers. The 1,000 and 1,800 turn transducers are also mechanically simple, having only a single pass 10:1 gear ratio between the input shaft and the two vernier resolvers. This mechanical simplicity allowed AMCI to design the HTT-20 transducers as a space saving, compact package. These resolver transducers have a 5/8" keyed shaft, AMCI's standard 1/4" X 20 mounting holes, sealed bearings, and a mil-spec connector.
