Highly Dynamic XY Linear Motor Scanning Stage, Introduced by PI

The L-731 magnetic linear drive ensures high velocity and acceleration.

Motion and precision positioning systems expert PI (Physik Instrumente) L.P. introduces a new compact metrology XY stage - the L-731. The magnetic linear direct drive ensures high velocity and acceleration, ideal for inspection and microscopy.

High Travel Accuracy, Stability
With a travel range of 205mm square and solid velocity to 100mm/sec, the L-731 delivers high accuracy and smooth motion. Precision crossed roller bearings with anti-creep cage assist guarantee superior guiding accuracy (1.5µm straightness for loads up to 20kg).
An integrated optical reference encoder and limit switch provide further positioning control and accuracy for this compact stage with 5nm resolution. DC servo motor versions are available on request.

Standard and Custom
PI has in-house engineered solutions with over 4 decades of experience working with customers to provide products that meet application demands, and can quickly modify existing product designs or provide a fully customized OEM part to fit the exact requirements of the application.
Applications of the L-731
Fields of applications include automation, semiconductor applications, photonics, bio-nano-technology, metrology, microscopy, micro-manipulation, including cleanroom applications.

Universal Robots - Collaborative Robot Solutions

Universal Robots is a result of many years of intensive research in robotics. The product portfolio includes the UR5 and UR10 models that handle payloads of up to 11.3 lbs. and 22.6 lbs. respectively. The six-axis robot arms weigh as little as 40 lbs. with reach capabilities of up to 51 inches. Repeatability of +/- .004" allows quick precision handling of even microscopically small parts. After initial risk assessment, the collaborative Universal Robots can operate alongside human operators without cumbersome and expensive safety guarding. This makes it simple and easy to move the light-weight robot around the production, addressing the needs of agile manufacturing even within small- and medium sized companies regarding automation as costly and complex. If the robots come into contact with an employee, the built-in force control limits the forces at contact, adhering to the current safety requirements on force and torque limitations. Intuitively programmed by non-technical users, the robot arms go from box to operation in less than an hour, and typically pay for themselves within 195 days. Since the first UR robot entered the market in 2009, the company has seen substantial growth with the robotic arms now being sold in more than 50 countries worldwide.
