Product Description

412LXR Positioner

The 412LXR is a slotless, brushless linear servo motor/square rail bearing positioner housed within a
high strength, aluminum body with magnetically retained protective seals. The positioner is powered by
three rails of high energy rare earth magnets. Load bearing members provide heavy load and moment
capacity, dynamic stiffness and precise straightness and flatness of travel. The positioner’s integral linear
encoder provides high precision, non-contact positional feedback with selectable resolutions from 0.1 to
5.0 microns. The positioner is also offered with proximity limit & home sensors, a “Quick Connect”,
extended life, and a cable transport system.

Unpacking

Unpacking

Carefully remove the positioner from the shipping crate and inspect the unit for any evidence of shipping
damage. Report any damage immediately to your local authorized distributor. Please save the shipping
crate for damage inspection or future transportation.

Incorrect handling of the positioner may adversely affect the performance of the unit in its application.
Please observe the following guidelines for handling and mounting of your new positioner.

•

DO NOT allow the positioner to drop onto the mounting surface. Dropping the positioner can generate impact
loads that may result in flat spots on bearing surfaces or misalignment of drive components.

•

DO NOT drill holes into the positioner. Drilling holes into the positioner can generate particles and machining
forces that may effect the operation of the positioner. Daedal will drill holes if necessary; contact your local
authorized distributor.

•

DO NOT subject the unit to impact loads such as hammering, riveting, etc. Impacts loads generated by
hammering or riveting may result in flat spots on bearing surfaces or misalignment of drive components.

•

DO NOT lift the positioner by cables or cable management system. Lifting postioner by cables or cable
management system may effect electrical connections and/or cable management assembly. The unit should
be lifted by the base structure only.

•

DO NOT push in magnetically retained strip seals when removing positioner from shipping crate. Damaging
strip seals may create additional friction during travel and may jeopardize the ability of the strip seals to protect
the interior of the positioner.

•

DO NOT submerge the positioner in liquids.

•

DO NOT disassemble positioner. Unauthorized adjustments may alter the positioner’s specifications and void
the product warranty.
