The MTM Series linear stages feature an all-steel construction and combine high stiffness and thermal stability with a low profile design. Recommended for up to 250 mm travel, MTM stages can bear up to 100 kg with an exceptional high axial load capacity up to 200 N.For durable, linear motion, opposing single-row bearing surfaces are precision-ground from tool steel. Smooth motion is provided by a diamond-corrected lead screw and a matched, precision-lapped nut. The nut design includes anti-backlash preloading and a sophisticated decoupling system that prevents lead screw eccentricity errors from affecting stage movement.All MTM stages include a center home position switch, supplemented by an index pulse signal from the encoder for precise origin location. The home position may also be set to either end of the stages travel via an external switch on the stage body.
Stepper-motor-driven stages are offered in four versions.Two mini-step drive versions with resolutions of 1 µm (PP1) and 0.1 µm (PP.1). These combine high speed positioning and smooth displacement from 1/10-step per encoder count driving mode. For ultra-smooth low-speed positioning, micro-stepping up to 250x is possible using Newport Motion Controllers.Two full-step versions with resolutions of 1 µm (PE1) and 0.1 µm (PE.1). These are primarily designed for applications requiring the position to be maintained within the stages resolution when power is switched off, such as operation in a vacuum.
Two DC-motor-driven configurations are available with resolutions of 1 µm (CC1) and 0.1 µm (CC.1). These feature a built-in tachometer to provide superior speed stability.
All MTM Series Long Travel Linear Stages are compatible with the XPS Universal High-Performance Motion Controller/Driver and select models are compatible with the ESP301 and SMC100. Refer to the table below for additional information.
