Miniature linear positioner series for lab automation and light payload industrial applications

For OEMS in the business of building small instruments who want to bring their product to market faster, the Parker LCR is a linear positioner family that provides the smallest form factor with easy to use flexibility unmatched by most competitive products. The ideal solution for OEM instrument manufacturers and laboratory instrument applications, the LCR Series is a complete solution offering users unmatched flexibility in a small footprint linear actuator. The LCR Series offers a complete screw- or belt-driven actuator, including motor and drive.

The fine lead screw offers higher resolution and higher thrust with lower motor torque. The high lead screw also provides users with a higher speed solution and screw drive positioning capabilities. As an alternative to the screw driven options there is the LCR belt drive which is perfect for high speed motion or long travel (up to 1m) applications. Pairing these drive technologies with the different bearing designs (square rail or glider bushing), now available from Micromech, the LCR offers a complete miniature linear positioner with a sealed body design.

The major features of the LCR are: 22, 30, and 45mm frame sizes, stepper or servo motor options, an integrated drive option, rugged square rail design or economical slider bushing design.  There is also an encoder feedback option, direct inline or parallel motor mounting options, cables connectors fitted for ease of installation and they are RoHS compliant (Restriction of Hazardous Substances Directive).

The positioners are ideal for OEM instrument manufacturers looking for significant ROI from an off-the-shelf yet tailor-made solution. This is a complete package which includes amplifier/drive (integrated drive option), motor, actuator, bearings, seals and limit sensors. For example the Ion Series stepper drive is an OEM-friendly miniature motion drive capable of up to 2 amps in a 25 x 25 x 85mm square package. The run current is adjustable via a potentiometer, it has auto standby adjustable current to reduce heat generation and power consumption and the stepper resolution is available to 3200 steps per rev. It is DIN rail mountable or mounts directly to the LCR Series linear positioners and importantly RoHS compliant.

Building on a proven life science track record with the MX80 and LP28 series, Parker developed an easy to use, high quality, ‘off the shelf’ linear actuator for payloads up to 100N at travel lengths up to 1m. This new LCR Series provides an un-rivalled set of product options ranging from drive technologies to bearing designs including:

  • 2 leadscrew-drive options
  • 2 belt-drive options
  • 22mm or 30mm profile widths
  • The longest travel lengths in the industry at this size: up to 1m
  • Stepper or servo motor options
  • Custom motor flange designs to quickly mount any motor
  • Flush mount NPN, PNP, normally open or normally closed limit sensors
  • Magnetically coupled stainless steel sealing strip
  • New ion drive for quick and easy connections to PLC or other motion controllers
