The AY110-200-04 Rotary Stage features a 200mm diameter table, 3.6 arcseconds (1/1000 of a degree) resolution and 100kg (220 lb) load capacity. This high load capacity, high precision Rotary Stage from OES (Optimal Engineering Systems) is just 83mm (3.268") high and the footprint is only 250mm by 267mm (9.843" by 10.512").  The stage has a 60mm (2.362") aperture, and a pattern of threaded mounting holes in the rotary table, and holes in the base for easy integration into new and existing applications. The range of travel of the AY110-200 Rotary Stage Series is 360 degrees of continuous rotation in both directions. The table is driven by a high precision 180:1 worm gear and has a resolution of 3.6 arcseconds with 10 micro steps-per-step micro-stepping drivers. The AY110-200-04 Stage is supplied with a Quadrature Optical Encoder for position verification. The AY110-200 Series of Rotary Stages has four motor options. Option -01 is Stepper Motor Driven with knobs for manual adjustments. Option -02 is driven by Three-Phase Brushless DC Servo Motors with Quadrature Optical Encoders, and option -03 is Brushed DC Servo Motor Driven with Quadrature Optical Encoders. Option -04 is Stepper Motor Driven with the knob replaced with Quadrature Optical Encoders for position verification. The low cost, low profile AY110-200-04 Rotary Stage Series is ideal for: Microscopy, laser positioning and machining, inspection, assembly, testing, and other critical applications. This black anodized stage has a load capacity of 100kg (220 lb.) and weighs 12kg (26.5 lb). The stage can be ordered as a complete plug-and-play system with RS-232, USB, joystick and keypad control, compatible motion controller.
