Compact Waterproof Tubular Linear Actuator
Compact Waterproof Tubular Linear Actuator
Our PA-ST4 compact waterproof tubular linear actuators are specialized for outdoor applications with tight space constraints. An ingress protection rating of IP67M ensures the compact waterproof linear actuator is well protected against dust and water submersions. Considering the compact tubular design, waterproof protection, and low full load current draw of 1.3 A, the PA-ST4 offers versatile force capabilities with a 45 lbs dynamic and 225 lbs static force rating.
The Molex Mini-Fit Jr 2-Pin Connector at the end of the cable, combined with a low current draw, allows for plug-and-play integration with existing systems across multiple applications and industries. A sleek, tubular form factor with versatile specifications works perfectly for home automation, machinery, automotive applications, and manufacturing use cases. For a full list of specifications and dimensional drawings, please see our PA-ST4 compact waterproof linear actuator Data Sheet.
MOUNTING OPTIONS:
The BRK-ST4 bracket set is designed for our PA-ST4 compact waterproof tubular linear actuators and allows for a simple installation process on the stroke rod and motor-end mounting points. For more detailed information and specifications, please see our brackets product page.
CONTROL SYSTEMS:
The low current draw allows for connectivity with most of our control systems. For more information about our plug-n-play control boxes and development micro-controllers, please see our control systems page.

Complete Guide to IP Ratings
Some of the most frequently asked questions we receive is to do with IP protection and ratings. W...
Depending on your application, there are different specification requirements you should consider when determining the linear actuator you need. These requirements include force, stroke, speed and mounting dimensions. For detailed actuator information, you can refer to either the datasheet or the specification table located on the selected actuator's product page. You can also contact us to speak with one of our expert engineers.
Duty cycle is the fraction of the working period in which a linear actuator can remain active. You can calculate the duty cycle of a linear actuator by using the following equation: Duty cycle (%) = (Time the linear actuator is active) / (Time for one working period)
For example: With a 25% duty cycle, an actuator can run for 5 minutes continuously before needing to rest for 15 minutes before operating.
Stroke is the travel distance of the extending rod. To find the stroke length you require, measure your application from the fully retracted position to the fully extended position. The difference will equal the stroke length you require.
We always recommend purchasing an actuator with a higher force rating than what the application requires. If unsure of your force requirements, this article may help you calculate this: How to Calculate Force to Find the Right Linear Actuator
Yes, this is possible. However, it does depend on the units you are currently using. To synchronize actuators, they require a form of feedback such as a potentiometer or hall effect sensors. For more information, see below some of our key content regarding linear actuator synchronization.
The control box you choose should be able to provide sufficient voltage and current rating to your actuator. If you are unsure of the specifications, please contact us.
Alternatively, you can also find compatible control boxes on your selected linear actuator's product page.
Backdriving is when an actuator starts sliding down under load, when it is either overloaded or when the actuator has been damaged. Watch the video.
What Does Dynamic and Static Load Ratings Mean?Dynamic load rating is the amount of weight an actuator can pull or push safely when being powered. Static load rating is the amount of weight the actuator can hold or withstand without back driving when it is not being powered. For example, let's just say you have an actuator installed on a window and the static load rating of the actuator is 100lbs, it could experience backdriving when there is a high wind event, which means there will be more pressure exerted on the actuator which would exceed the 100lbs load rating of the actuator.
What Is Lateral Loading?Lateral loading is when the actuator experiences forces from the lateral plane. Actuators are not meant to handle lateral forces at all so if it experiences any lateral forces, it will likely damage the actuator or bend the rod. So it's advised never to use lateral forces and always make sure the actuator is fully in line or in sync with your application, so it does not take any load other than the axial load.
