Parker Hannifin’s (www.parkermotion.com) Electromechanical Automation Division has released a miniature screw-driven positioner inspired by its award-winning MX80 family, the MX45S linear positioner. Measuring only 45 mm wide, the new MX45S has been specifically designed to meet the needs of OEMs for reliable linear positioning in space-restricted applications.

The positioner features an anti-cage creep cross roller bearings to allow users to conveniently position normal loads of up to seven kg (15.4 lbs) on three available standard travel lengths of 25 mm, 15 mm and five mm. The MX45S is supplied with a high-precision ballscrew or a high-efficiency leadscrew, both of which can produce 40 N of thrust at 30 mm/s and 20 mm/s linear velocities, respectively.

The MX45S linear positioner is suitable for various applications including fiber optic alignment, biomedical imaging, laser diode research and semiconductor inspection.

“The MX45S is designed for applications requiring small incremental movements, micron repeatabilities, smooth motion and high stiffness, all in an ultra-compact package,” said Product Manager Michael Szesterniak.

“In addition to superior performance, the MX45S is offered with several standard options to allow users to match the positioner’s performance with the application’s requirements.”

The stepper motor driven positioner also features ultra compact profile, standard multi-axis configurations and maximum velocity of 30 mm/s.

Aside from the standard features offered in the MX45S, it also provides several options to help match the performance of the positioner to the application requirements. The options include linear and rotary encoders, the ability to receive and order one of 11 pre-engineered multi-axis systems and digital limit/home sensor packs.
