Do linear actuators have limit switches?
Venture’s linear actuators consist of limit switches, which are used to control the stroke length of the device.
What switch do I need for a linear actuator?
To control a linear actuator, you need to use either a DPDT relay with a SPST (single pole single throw) switch or two SPDT (single pole double throw) relays with a DPDT switch.
What can you do with a linear actuator?
Most Common Uses for Linear Actuator

- Robotics.
- Food and Beverage Manufacturing.
- Window Automation.
- Agricultural Machinery.
- Solar Panel Operation.
- Cutting Equipment.
- Valve Operation.
How do you stop a linear actuator?
There are many different types of linear actuators. The simplest of these (such as our S series) have internal end-limit switches. These switches simply stop the actuator by cutting off the power when it reaches it’s end of stroke when retracting or extending.
Can an external limit switch be connected to a linear actuator?
External limit switches are easy to connect to your linear actuator and as previously discussed, provide a simple solution to stop the actuator from moving past a set position of your customization. Wiring the external limit switch to the linear actuator is extremely easy.
Are there relays that work with linear actuators?
We offer a simple relay kit in our store that is designed to work with electric micro linear actuators. For larger projects, there are relay boards available with 2, 4 and even 8 channels. You can find larger relays at RobotShop.
What does it mean when it says non adjustable limit switch?
When you’re reading the specs for a linear actuator and it says “built in limit switch” or “non-adjustable limit switch”, this indicates that when the shaft extends and retracts, it will not only stop at the end of the stroke, but the motor will also shut off.
How can I limit the travel of an actuator?
Simply connect them to the ground wire between the control switch and the actuator. You can install just one to limit either the extension or retraction, or you can install two, to limit travel in both directions.
