ETS-Lindgren's Value Series Model 2187turntables are designed for applications requiring a mid-sized turntable with reasonable weight load requirements. These turntables do not have the heavy-duty mechanism of the Model 2181 turntables, allowing them to have shallower installation depth.
All Model 2187 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 2187 turntables feature a durable bronze filament ground brush and matching wear strip to provide continuous electrical coupling with the ground plane.
All Model 2187 turntables include the ability to set mechanical limits for clockwise and counterclockwise rotation, using manually adjustable knobs. 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.
