How to Use an External Limit Switch with a Linear Actuator
An external limit switch is a very handy and cost effective means of controlling the travel of a linear actuator . Here we will go over how to use an external limit switch with a linear actuator. Most electric linear actuators are made with built-in limit switches. This means you are able to adjust the travel of the stroke to your precise desired position. Not all linear actuators are built limit switches. So what do you do when the linear actuators stroke is longer than you need? Installing an external limit switch is the simplest and most affordable method to control the travel in electric linear actuators where the limit switch is either non-adjustable or non-existent. There are three ways to control the stroke: Limit extension Limit retraction Limit both extension and retraction What is a Built-In Linear Actuator Limit Switch? All our linear actuators have internal limit switches at the fully extended and retracted positions. These limit switches ensure that when ...
