MI-56000 Family of Polarization Positioners

MI-56160

The MI-56000 Family of Polarization Positioners is available to support maximum loads of up to 3,000 lbs. The bolt-hole pattern on the positioner turntable is compatible with MI Technologies transmitting antennas and the mounting flanges for MI Technologies standard gain horns. A throughcenter hole facilitates installation of coaxial cable, waveguide, rotary joints, and RF components.

The MI-56000 Family of Polarization Positioners is supplied with variable speed, reversible, DC drive motors. Several models in each load-rated category provide a wide range of speed options. On specified units, synchro transmitters (for remote position readout and recording) and limit switches are available. The limit switches may be set to provide total travel from 20 degrees to 800 degrees. Unless specified, the limit switches will be set for 400 degrees of travel.

downloadpdfEach MI-56000 positioner is delivered as a single unit. 1:1 and 36:1 synchros are installed on units with speeds less than 5 rpm; only 1:1 synchros are installed on units with speeds more than 5 rpm. Limit switches are not included on positioners with speeds greater than 5 rpm. An installed RF path through each positioner is ordered as an option.

  • Versatile design features variable-speed, reversible DC drive motors
  • Each positioner possesses a through-center hole allowing installation of coaxial cable, waveguide, rotary joints and RF components
