The PJ201 piezoelectric potential shifter from Jianxing Technology is the second product of the PJ20xx series Z-axis piezoelectric potential shifter. The PJ201 piezoelectric displacement stage adopts a flexible hinge amplification mechanism optimized by finite element analysis, with a built-in high-precision capacitive displacement sensor for feedback control of the movement of the displacement stage, achieving nanometer level resolution. Compared with systems that use strain gauges for feedback, this product directly measures the relative displacement of the rotor and stator, with higher closed-loop accuracy. The PJ201 piezoelectric displacement platform optimizes space utilization through embedded installation holes, further reducing its volume. This product adopts a multi degree of freedom error suppression design to control pitch and yaw errors within ± 50 μ rad, which is more advantageous compared to similar products on the market.
Image: Physical product Recommended controller: PE101-1 single axis digital piezoelectric controller integrates capacitance sensor measurement circuit, supports multiple working modes such as open-loop, closed-loop, digital control, analog control, etc., is compatible with high-voltage amplification function, and has rich communication interfaces, including RS422, USB, Ethernet, etc. High precision control of the flexible hinge displacement table can be achieved.

What are the advantages of this product? 1. Adopting high-performance flexible hinge system Flexible hinges achieve high-precision displacement guidance without friction, enabling nanoscale position control. The wear-resistant design significantly improves the service life under high-frequency motion, reduces maintenance requirements, and is suitable for long-term high dynamic working conditions. 2. Small size, large stroke, high precision By designing embedded installation holes, the volume of the sports platform is further reduced, with PJ201 measuring only 40 × 40 × 17.5mm and a stroke of 100 μ m. Built in high-precision capacitive displacement sensor ensures the linearity and accuracy of the piezoelectric station. The unidirectional/bidirectional repeatability accuracy of the piezoelectric station is ± 2nm/± 5nm, with a linear error of 0.03% FS. 3. Multi degree of freedom error suppression Compared with traditional Z-axis motion platforms, the pitch and yaw errors are further reduced by optimizing the mechanical structure and assembly process.
Diagram: Main Technical Parameters In closed-loop control mode, test the Z-axis displacement of the piezoelectric station by 500nm and the time required to stabilize to an error band of ± 2.5nm. The piezoelectric station carries a load of 230g, and the internal sensors of the piezoelectric station collect data (25ksps sampling, sliding average, sliding window 158 points), obtaining a step time of 22ms.
