PI’s new M-417 linear stage provides 500 mm travel and half-micron resolution.  This motorized precision positioner can be computer controlled for automation and precision assembly applications. The linear translation stage can handle high duty cycles and boasts high velocity of 100 mm/second. Precision recirculating ball bearings provide guiding precision in the 100 µrad range over the complete travel range.

The low friction ball screw with a 2 mm thread pitch allows for maintenance free operation and the integrated highly efficient PWM servo amplifier improves cost efficiency while simplifying installation and operation – no extra amplifier required. For example, the M-417 can be driven by PI’s miniature, palm-top C-863 Mercury servo motion controller.

Closed-Loop Operation, Limit & Reference Point Switches

An incremental optical rotary encoder with 4000 counts/rev controls the position providing unidirectional repeatability of 0.5 µm. Non-contacting reference point and limit switches protect the mechanics from damage.

Dimensions and Application

The M-417 stage is 120 mm wide and 56 mm high. Its stress-relieved aluminum base ensures the stage's high stability. This low-profile positioning stage is well suited for automation and precision motion control applications for science and industry.
