Newport 850 Series Linear Actuators

  • Precise, Variable Speed, Linear Motion
  • Driven by Fractional-Horsepower DC Servo Motor
  • Two Motor Sizes


The Newport 850 Series Linear Actuators provide precise, variable speed, linear motion. The actuators are driven by a fractional-horsepower DC servo motor with an integral position encoder. The 850 is offered in two motor sizes, each with a multitude of gear reduction ratios. Its velocity servo electronics, an integral part of the actuator package, assure that changing load conditions will not affect velocity, cause motor burnout, or shape the encoder signal. In addition, the servo electronics sense motor stalls and end-of limits to prevent mechanical binding.

The position information from each actuator comes from a built-in optical encoder. In the standard configuration (33.3346 TPI, 262:1 gear-head, and 1616 motor), the lead screw pitch, gear-head ratio, and number of encoder pulses per revolution have been selected to make each encoder count equivalent to 0.100 micron of linear travel.

Product Family: 850, 85O
