ETS-Lindgren's Classic Series Model 2181 turntables have a long legacy of durability and trouble free operation since the 1980's. This series of turntables have been installed both indoors and outdoors at test sites around the world and have set the standard for others to follow. Available in a variety of standard diameters, weight loadings and drive speeds, these turntables can also be customized to meet your exact requirements.
All Model 2181 turntable tops are precision machined using CNC milling equipment for a smooth, even platform that is warp resistant. The nominal tolerance for flatness is .32 cm (1/8 in) over two meters. Run out tolerances are less than or equal to .16 cm (1/16 in).
All Model 2181 turntables feature a durable bronze filament ground brush and matching wear strip to provide continuous electrical coupling with the ground plane.
All Model 2181 turntables include the ability to set mechanical limits for clockwise and counterclockwise rotation, using manually movable pins. Within the mechanical limits, soft limits can be set using the Model 2090 Positioning Controller. The turntables can also be set for continuous rotation. Optional slip rings for EUT power signal lines are recommended if continuous rotation is performed.
Signal I/O between the motor base and optional ETS-Lindgren Model 2090 Positioning Controller is fiber optic, eliminating a potential source of RF interference. The turntable includes 10 meters of fiber optic cable.
