There may be cases when you want to move an object a longer distance than what the actuator's stroke length is. You can achieve this by using a telescoping actuator or you can use the physics of mechanical leveraging to your advantage. Common examples of this are the scissor lift or what our friend Mike Senna, the creator of the Wall-E Robot, did with his DIY Chicken Coop Automatic Door Opener. The physics behind these applications is using a ...

If you require a quiet actuator for your application where noise pollution is a concern, the best way is to check out the noise rating along with verifying this value with a decibel chart. Decibels were named to honor Alexander Graham Bell, the inventor of the telephone – the term refers to the intensity of a sound and is often referred to as dB for short. While many people are aware of what the term decibel means, not many can accurately say ...

Have you ever faced a situation where you must connect a high current actuator with a low current control box? Heavy duty actuators like the PA-17 and PA-13 have a significantly higher current draw than the average actuators and many control boxes are not designed to handle such high current. However, we can resolve this by using relays to bypass the current limit on control boxes. In this blog, we will help you with a safe way to use a standa...

Operating an actuator, for the most part, should be easy and straightforward, ...

One of the most important steps in selecting a linear actuator is choosing the appropriate force rating. It is quite simple when the application requires a load to be lifted vertically, wherein the weight of the load being lifted is equal to the force required from the actuator. A more challenging scenario is if you have a hinge-type application, as commonly seen with lids, trapdoors, and windows. In this article, I will use a sample trapdoor...

Our FLTCON control box series are primarily used to operate our table lifts and lifting column sets. They can also be used as an actuator control box for certain actuator models, as long as they have a Hall Effect sensor and a 24VDC input.

Lead screws have been widely used to generate linear motion from a rotary motor. It can convert circular motion to linear motion by turning the screw with the nut fixed in place, or turning the nut while the screw remains in place. Today, we will look at two of the most popular screw types in the automation industry: ACME Screws and Ball Screws.   ACME Screw ACME screws use a trapezoidal shape thread to roll on to the lead screw. As the shaft...

There are two methods of multiple actuator control – parallel and synchronous. Parallel control outputs a constant voltage to each actuator, while synchronous control outputs variable voltage to each actuator. The process of synchronizing multiple actuators is necessary when implementing two or more actuators to move at the same speed.  This can be achieved with two forms of positional feedback– Hall Effect sensors and multiple turn potentiom...

Sitting for long periods of time is never a good idea; it can lead to many health issues including obesity, increased risk of cancer, shorter life spans and long term posture problems.  But for some it’s a part of their daily life, primarily those working a desk job that requires sitting at a computer all day. While it is recommended to take breaks and walk away (literally) from your work throughout the day, some people just don’t have the tim...
