The M-692 series of ultrasonic linear translation stages from Physik Instrumente (PI) are suitable for high-speed positioning operations within space-limited applications such as biotechnology, micromanipulation, microscopy, automation, research and development and quality assurance testing.

The low-profile, closed-loop, linear motor-equipped micropositioning systems are offered in two standard versions — the M-692.1U4 (20mm stroke) and the M-692.2U4 (90mm).

The series is scalable and may be varied to provide travels ranges of up to 300mm for OEM quantities.

PI also offers the C-867 motion controller, which improves the stage’s performance and integrates the drive electronics to generate the piezoceramic element’s ultrasonic oscillations.

Additionally, the C-867 features continuous automatic drive frequency adjustment and dynamic parameter switching that the company says optimises dynamics and settling behaviour.

Key features

  • Stages can be fitted with integrated linear encoders to enable backlash-free positioning
  • Stages can be arranged into compact XY systems
  • Vacuum-compatible versions can be requested

Physik Instrumente

PI is a global manufacturer of high precision positioning systems and products based on piezo technology. Used in markets as diverse as biotechnology, semiconductor, defence and astronomy, PI’s products work to improve the speed and precision of many cutting edge processes. Actuators, sensors and positioning systems with either sub-micron or nanometre level precision; many customised for the end user, are included in the product range.

With manufacturing and subsidiary offices around the world and a workforce of more than 500 PI provides direct local support where it is needed. Products range from component level piezo ceramic assemblies to six axis hexapod positioning robots. PI manufactures its own piezo ceramic material including multilayer devices that incorporate its patented ceramic insulation technology. Lead free ceramic technology is now also included in the company’s product range. With the flexibility and continuity of supply offered by having control of piezo ceramic production comes security and speed of delivery for customers who rely on or are looking to move into this area of technology. PI’s piezo ultrasonic and step drive motor technologies offer unique performance including self-locking capability, high force or high speed and non-magnetic and vacuum compatibility.
