PM500-1A In Stock

The PM500-1A by Newport is a Ultra-Precision Motorized Actuator, designed to merge ultra-precise positioning with impeccable reliability. Engineered to meet the most demanding standards, this actuator showcases laboratory-grade quality and performance coupled with the dependability expected in production line environments. The PM500-1A integrates cutting-edge direct-output metrology, resulting in unparalleled dynamic performance. Specially designed to replace 3/8 inch diameter micrometers, it offers versatile compatibility with a wide array of positioning components. Notably, its user-friendly manual adjustment knob facilitates intuitive positioning, a feature available even when the motor is deactivated. The actuator's proprietary non-contact read-head technology effectively eradicates hysteresis and wear, ensuring sustained precision.

Crafted from stress-relieved, high-strength aircraft grade aluminum, the PM500-1A boasts remarkable durability. Its robust construction is further enhanced by a high-quality lead screw and a low-friction preloaded nut, which collectively contribute to exceptional stiffness, extended operational lifespan, and enhanced load-bearing capabilities. With a DC motor drive engineered for cool operation, the actuator guarantees a superior mean time between failures (MTBF) of over 20,000 hours. The PM500-1A employs an innovative motor-to-lead screw design that optimizes space utilization while effectively mitigating micron-scale torque and positioning errors through its non-rotating spindle configuration. This forward-looking design integrates a linear glass scale within the moving spindle assembly, eliminating errors induced by the drive train that remain unaccounted for when utilizing an encoder attached to the motor. The embedded scale ensures accuracy better than 1 µm across the entire range of travel and features a fiducial track for reading the absolute origin position.
