(Discontinued) X-GSR-E Series
Large diameter, motorized goniometers with built-in controllers and motor encoders
About This Series
Zaber's X-GSR-E Series devices are computer-controlled, motorized goniometers with a large diameter of rotation and long travel. They are stand-alone units requiring only a standard 48 V power supply. The built-in motor encoder allows closed-loop operation and slip/stall recovery features. 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.
With a low, narrow profile and asymmetric mounting options, these stages excel at angular scanning applications where keeping a clear view of the central target is critical. Curved crossed-roller supports give these devices smooth motion and the roller cam drive provides exceptional accuracy and eliminates backlash. Like all of Zaber's products, the X-GSR-E Series is designed to be 'plug and play' and very easy to set up and operate.

- An indexed knob provides convenient manual control.
- X-GSR150 and X-GSR225 can be mounted together using AP169 to share a common centre of rotation.
- Control all units in the daisy-chain via serial port (with a locking X-SDC cable) or USB (with an X-USBDC cable).
- Integrated motor encoder, stepper motor controller and motor driver allows for easy-to-use control with stall detection.
- Two offset mounting surfaces give you the option to mount a payload at either end of travel. This maximized angular reach while minimizing total height and potential for interference.
- Daisy-chain additional units with a locking X-DC02 cable or X-DC06 cable. Power can also be shared in the chain.
- High efficiency roller cam drive reduces backlash and delivers more torque than a comparable worm gear.
- 200 step per revolution stepper motor, microstepped up to 256x to provide smooth and precise motion.
Easy Set-Up
Zaber's devices can share both data and power through a daisy-chain, which reduces cabling and makes set-up as easy as 1, 2, 3:
- Connect the Zaber device to your computer via USB or RS-232 port.
- Connect the power supply to your Zaber device.
- Send instructions or automate your set-up using the Zaber Launcher.
