NSI-SC-5636
 Compact Heavy Duty Rotation Stage with Encoder and Slip Ring Options

DESCRIPTION

The NSI-SC-5636 is a high accuracy rotational positioner which is ideal for use as an azimuth stage for far-field measurements or as a theta or phi rotation stage for spherical near-field systems.
CAPABILITIES

The rotator can support a vertical load of 2,000 lbs (909 kg) and includes an integral precision stepper motor. The stage interfaces to a standard NSI 2000 antenna range controller (NSI-SC-5911). The stage can be configured with an optional encoder to improve accuracy, optional slip-ring assembly to pass signals through the stage, optional RF rotary joint and an integral motor driver package to allow it to directly take pulse and direction input signals from the control computer.
