Flexure Guides
P-753 positioners have flexure guides for friction-free motion and high guiding accuracy.
A flexure guide is an element that is free of static and sliding friction. It is based on the elastic
deformation (bending) of a solid (e.g., steel) and does not have any rolling or sliding parts.
Flexure elements have a high stiffness and load capacity. Flexure guides are maintenance and
wear free. They are 100 % vacuum compatible, function in a wide temperature range and do
not require any lubricants.
3.6.3
Capacitive Sensors
Capacitive sensors measure the position directly on the motion platform (direct metrology) and
work without contact. Neither friction nor hysteresis interferes with the motion, which allows
excellent linearity values to be achieved together with the high position resolution. In
conjunction with suitable electronics, capacitive sensors achieve the best resolution, stability,
and bandwidth.
3.6.4
ID Chip (Only Models With DSub Connector)
An ID chip is located in the D-sub connector of the P-753. When the P-753 is calibrated at the
factory with digital electronics, the calibration data is saved on the ID chip together with
specific product information. During switch-on, the digital electronics read the data from the
ID chip of the P-753 connected. An P-753, whose ID chip contains the calibration data, can
therefore be connected to any suitable digital electronics without renewed calibration.
For more information on the ID chip, see the manual of the controller used.
