AVAILABLE POSITION ENCODER FOR CLOSED-LOOP OPERATION

:.........................................................................................

Optoelectronic Readout /NUM
This encoder system allows fully automated, closed-loop positioning operation with high resolution compatible with ambient conditions, ultra high vacuum, and magnetic fields up to 7 T. It delivers a relative position to a reference with a sensor resolution of 10 nm and a repeatability of < 400 nm.

General Functionality
Similar to the /NUQ sensors, optional /NUM sensors are fully integrated into the piezo stepper device. The electronic controller required for driving and position readout is the ANC350. Its fully automated software and the plug-and-play design make this positioning system the ideal candidate for a variety of positioning and alignment tasks. Features like the ‘Automatic Amplitude Control’ enable to drive the positioner with a constant step size which consequently results in constant motion velocity.

Resistive Readout /RES
Specifically designed for the operation at low temperature, the resistive /RES encoder provides a readout of the absolute sample position with a resolution of approximately 200 nm and a repeatability of 1-2 μm. Apart from operation at low temperature, the /RES encoder is also compatible with ultra high vacuum and high magnetic fields.

General Functionality
In /RES equipped stepper positioner models, a resistive element working as a potentiometer is fully integrated into the positioning stage. The electronic controller required for driving this readout system is the ANC350. This controller allows to adjust the operating voltage of the sensor element in a range from 0.1 to 2 V.
