OES’ 39mm-diameter AR39-AH rotary table features high precision and a hollow core.
Optimal Engineering Systems, Inc. (OES) has introduced its AR39-AH, a miniature rotary table with a 58mm (2.283 in) by 100.5mm (3.957 in ) footprint and includes a 2-phase 1.8 degree stepper motor. Measuring 35mm (1.378 in.) high and a diameter of 39mm (1.535 in.), the table has a precision pattern of 6 8-M2x4L threaded mounting holes and an 8mm (0.315 in) diameter through hole. Its range of travel is a full 360 degrees of continuous rotation. The table is driven by a 120:1 worm gear at speeds up to 75 degrees per second and has a resolution of 0.001 degrees (3.6 arc-sec) with a 10 micro-step per step stepper motor driver. It also features a positional accuracy of 0.05 degrees (180 arc-sec) and has a load capacity of 3kg (6.6 lbs).
