NLS4 have been designed for a variety of applications in research and other industrial areas requiring precision positioning such as in semiconductor processing, fiber optics manufacturing and biotech automation.
The design of the NLS4 series stages was optimized for maximum stability and performance with the use of FEA analysis and incorporates the best in materials and component selection.
For more reliability and durability, the ways and leadscrews are protected with a strong machined cover and the encoder is mounted internally directly to the leadscrew rather than being exposed to shock and contamination when mounted in the rear of the motor.
All NLS4 series stages are machined from 6061 aluminum alloy to provide a light yet stiff and stable linear stage.
The drive system utilizes a stainless steel ACME leadscrew with internally lubricated plastic drive nut. The drive nut offers zero backlash operation that automatically adjusts for wear to insure zero backlash for the life of the stage.
The use linear guide bearings provide a smooth motion with high load capacity and stiffness. Since the carriage is supported over the entire travel of the stage, a good cantilevered load capacity can be achieved.
Separate connectors for motor power and limit/encoder signals are provided for ease of operation. Integrated limit switches and a high torque size 17 stepper motor are supplied as standard items.
