The XAB-xxxx-20-30-01 integrates a two-axis Alpha-Beta goniometer on top of a single-axis linear actuator. The Beta-axis has a travel range of
+/- 15 Degrees with a rotation height of 50 +/- 0.2 mm. The size of the table is 65 by 65 mm (2.559 by 2.559 inches). The gear ratio is 1 degree (stage) : 252 Degrees (motor). The travel guide is precision crossed-roller guide.
The lower goniometer (Alpha-axis) has +/- 10 Degrees of rotation driven by a worm gear with a drive ratio of 352 Degrees of motor rotation to 1 degree of stage rotation.
The Alpha and Beta axes have
a caliber indicator to display the angle of rotation which is ideal for: Crystallography, metrology, light measurement, measurement of surgical cutting blades, microscopy, laser positioning, and inspection applications.
The threaded mounting holes in the Beta-axis and mounting holes in the X axis assure easy integration into new and existing applications.
T
he XAB-xxxx-20-30-01 features Two Phase Stepper Motors with knobs for manual adjustments which can be replaced with optical encoders for position verification. The
XAB-xxxx-20-30-02 is driven by Three Phase Brushless Servo Motors with Quadrature Incremental Optical Encoders for closed loop operation that offer the highest resolution, repeatability, and travel speeds.
This series requires a
Motion Controller
that can be ordered as a complete plug-and-play system with joystick and keypad.
