X-RSB-E Series: High speed motorized rotary stages with built-in controllers and motor encoders
Continuous 360° rotation stage
Speeds up to 500 rpm
50.8 mm aperture
Built-in controller; daisy-chains with other Zaber products
Multiple motor configurations
Encoder position feedback with slip/stall detection and automatic recovery
Zaber's X-RSB-E Series rotation stages have a 120 mm table diameter and a 50.8 mm (2 inch) aperture. They feature a compact footprint, low profile, and a load capability of up to 50 kg. With a maximum speed of 500 rpm, these rotation stages are ideal for the rapid positioning of light loads to within a fraction of a degree.
They are stand-alone units requiring either a standard 24 V or 48 V power supply. A built-in motor encoder allows for closed-loop operation and slip/stall recovery features. There are two motor configurations available: up and down. Motor up configurations allow flush mounting of the device to a flat surface, and motor down configurations allow for a full 360° movement of loads that extend past the edge of the stage top. An indexed knob provides convenient manual control for versatile operation even without a computer.
These stages connect to the RS-232 port or USB port of any computer, and they can be daisy-chained with any other Zaber products. The daisy-chain also shares power, making it possible for multiple X-Series products to share a single power supply. Convenient locking, 4-pin, M8 connectors on the unit allow for secure connection between units. Like all of Zaber's products, the X-RSB-E Series is designed to be 'plug and play' and very easy to set up and operate.
Zaber's positioners with built-in controllers, stand-alone controllers, and joysticks are divided into three series: the T-Series, the A-Series, and the X-Series.

Specification Charts and Notes
Thrust or torque is a function of speed. The values given above are maximums. These values cannot both be achieved simultaneously (i.e. at maximum speed, the unit will not produce maximum thrust).
