Having something attached to a linear actuator in order to prevent it from moving more than you want or is required is something which can come in extremely handy when the task at hand requires more control. While some electric actuators are built with a programmable limit switch, most are not; these models come either with nothing limiting movement at all (therefore with no way for users to control the distance the actuator travels), or a limit placed at the extreme ends of the shaft only (to control the movement to some extent).

You might hear that we live in the times of the fourth industrial revolution. It is characterized by a total digitalization or implementation of computing innovations in multiple areas of a human life. Nevertheless, the notion of revolution in terms of technologies does not mean an absolute shift to some state-of-the-art advances. In fact, it lies in the improvement of the accustomed solutions used in manufacture, household, entertainment, transportation etc. The following text will introduce you to a widespread technology that is not esteemed in a proper manner by the population. It refers to an electric linear actuator and its application scope.
Today’s emphasis on linear actuators requires a similar emphasis placed on the actual motion which is created by the actuator. The two main ways to produce this motion rely on lead screws and ball screws, each of which has their own uses and advantages over the other. In this article, we will look closer to each type and find the difference between ball screw and lead screw.
The simplest process to wire a 12v linear actuator to a rocker switch is to use a wiring kit. The installation kit comprises of two wires; red and black wires that are already configured with jumpers to make the connection much easier. Other items in the wiring kit include, the Molex connectors, fuse holders containing fuses, limit switches and diodes.
The installation kit limits the stroke size and extends the length of the wire to be connected to the actuator. These two wires are important because they are used to control the motor of a linear actuator. The connection process can be performed using two options; these include using the momentary rocker switches and non-momentary switches.
One of the most important factors to take into consideration when buying a linear actuator is the environment it will be used in; there are many contaminants, particularly in an industrial setting, which could be harmful to the proper functioning and the overall health of a 12v electric actuator.
The three most common problems which are faced when using electric actuators are dust, moisture, and corrosion. Dust and other contaminants like dust act to clog up the moving parts of the actuator, rendering it less functional and more liable to break or otherwise go wrong. Moisture and corrosion tend to go hand-in-hand when it comes to actuators because leaving an electric actuator exposed to moisture can have the effect of letting the metal rust, which then leads to equipment which does not function properly, and will most likely break. Another problem that is encountered with moisture is the effect it will have the electronics themselves – water and electricity don’t mix, and at best the water contamination will lead to equipment which no longer functions. At worst, the equipment will lead to whoever uses it to be hurt.
