8" Stroke: 180 lb Thrust Linear Servo

While a linear servo may appear similar to a linear actuator, it functions quite differently.  A linear servo responds to a PWM signal - to achieve the same results, a linear actuator would require a motor controller with a feedback loop capable of responding to a PWM signal.  The linear servo is designed to simply plug into a servo controller and run without any additional tuning or wiring from the end-user.  The advanced internal circuit board is able to accept a PWM signal from about any servo controller which means that you can operate this unit from a wired servo controller such as our Dual Servo Driver or Servo Recorder, a wireless transmitter and receiver or even a microcontroller such as an Arduino.  The closed-loop feedback allows the linear servo to be driven to any location within its stroke range by simply sending the corresponding signal to the servo from the servo controller.  The internal circuit board is able to check the current position reading from the internal potentiometer and accurately control the position of the extension tube by supplying power to the motor until the called-for position has been reached.

The male XT30 connector requires a 12V input with a minimum of 5A in order to power the linear servo.  When power is supplied to the XT30 connector, it will automatically feed 5V (500mA) down through the twisted lead that plugs into your servo controller so that both the linear servo and the servo controller can run off the same power source. For tips on powering a linear servo see the tech tips section below.

Linear servos can be used in place of pneumatics and hydraulics.  The ACME screw that drives the extension tube provides efficient linear thrust and allows the linear servo to handle immense static loads without being back-driven even with power removed.  The metal construction of the linear servo provides tremendous durability and reliability.  Linear servos are able to operate in any orientation and provide equal force in both the pulling and pushing directions.  The mounting clevis nearest the motor is fixed but the mounting clevis on the extension tube is able to be rotated if your application requires the holes to be oriented differently.  Mounting holes are 5/16" diameter.
