Feedback Linear Actuators

About

We're proud to introduce our new line of Actuators featuring Optical Sensors to provide feedback. When you need to know the exact positioning of your actuators, the OS Series is what you need. These powerful feedback linear actuators come with a built-in optical sensor that provides feedback when you need it. The OS Series has no built-in controller but does provide single-phase pulses as a position feedback signal that can be input to an external controller such as an Arduino. Replacing an existing actuator? Use the linear actuator replacement guide to compare published force, stroke, voltage, speed, feedback, and IP-rating data before choosing a FIRGELLI option. The OS series is equipped with a 10 hole optical encoder disk that with the gearing to the actuator output shaft will send 100 pulses/inch of stroke ( +/- 5 pulses). There are three force options available ranging from 35 to 400 lbs. These units come equipped with built-in limit switches, are manufactured with high-grade aluminum outer and inner tubes, and come in various stroke lengths from 1" - 30". Linear actuators with position feedback have either built-in Potentiometers, Hall sensors, or Optical Sensors. We offer Linear Actuators with position feedback that have all 3 Feedback options. (Optical, Potentiometer, and Hall sensor) each Feedback actuator type has its own benefits and drawbacks. As such we wrote an article about the advantages and disadvantages of each one, so you can really understand the difference to help you decide which will best suit your application. Article: Understanding how Feedback Linear Actuators work Our 3 types of Feedback Linear Actuators include: Potentiometer linear actuators. These Actuators offer 3 wire voltage divider systems. Basically, the Potentiometer has 3 wires, where one wire represents 0v to represent the retracted position of the Actuator, +ve input voltage to represent 100% of the max travel. So if you put 12v into the potentiometer, that 12v will represent t
