RT-2 Motorized Rotary Stage

The RT-2 Series motorized rotary stage features a compact and low profile size.

The RT-2 has a low profile coming in at just over 38mm thick. The design takes advantage of a thrust bearing systems for the table movement. This design approach offers excellent stability and low cost. The RT-2 utilizes a worm gear drive with available gear ratios of 80:1 and 40:1. The 40:1 gear ratio will provide a higher output speed over the 80:1 gear ratio. The worm gear is preload to minimize the backlash in the gear train. This small rotary stage comes standard with a NEMA 17 stepper motor and an optional 4000 CPR rotary encoder.
