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.

AMCI offers a complete line of resolver interface solutions, enabling you to easily configure a resolver-based position feedback system in your favorite PLC, PAC, or network.
