attoMOTION product finder Our positioners are named by the base modell (i.e. ANPx101) followed by several extensions describing the type of position sensor and suitable environment. You can determine in just three steps which attocube product line fits your needs best (step 1), if you need a position encoder and what is the ideal version for you (step 2) and what environmental options you require to get the most suited positioner for your applica- tion. In the end you will end up with something like ANP/RES/LT/UHV. To choose the exact positioner go to the corresponding section in the catalogue...

Glossary environmental options Glossaryopen and closed loop positioning Temperature Range Temperature All attocube positioners can be used in a temperature range of 0°C to 100°C in a non-condensing environment. For temperatures lower than this range special versions (/LT, /ULT) are available, see below. Due to the intrinsic nature of the semiconductors used in our precise optoelectronic encoder the /NUM sensor readout will only work up to an encoder temperature of 55°C.

encoder options sensor terminology Most of our positioners are available with optional encoders for closed loop control. The encoder allows to read back the actual position, while a feedback loop integrated into the corresponding electronics is used to minimize the difference between target position and actual position. Setpoints can either be defined in a software interface (ANC350, ECC100) or on the front panel of the closed loop electronics (ANC350). The available encoder types are described below. Sensor Resolution Sensor Repeatability The working principle of this encoder type is based on...
