Many factors affect the price of an actuator, which is a type of controller, and keeping prices down usually means choosing an actuator that fits the need without going over specifications. There are several actuator types — including linear, mini and track — and they have different price tags. Another factor that determines the price of an actuator is its stroke length, which allows the device to handle short or long operations. To make the associated device work, the actuator has to move, and the movement speed also will affect the price of the item. Some actuators are made with special features, such as being fire retardant, or will be made with extra-durable materials that will affect prices.

In the actuator market, many different actuator types are made for controlling different devices. Some move back and forth, like the track actuator, while others — like the mini actuator — are very small but deliver a high amount of power relative to the size. Each actuator type requires different materials and pieces to fit a certain need, so one factor in determining the price of an actuator is its function.

Most, but not all, actuators have a stroke length that allows the actuator to move a specific amount. For example, a small actuator could move a curtain for a window, while a large actuator could move a curtain for a movie screen. Longer stroke lengths will increase the price of an actuator. Extra length is rarely required, so users typically only need to get actuators that exactly fit their needs.

Actuators are made to move devices or components and are rated for speed. While faster units are generally better, especially if the user or customer expects the associated device or component to move quickly, some applications may be unable to handle quick movements. Just as with stroke length, a user trying to save money should only pick an actuator that fits his or her needs, because this greatly affects the price of an actuator.

Some actuators come with special features that make them safer or protect them against shock, and some are made of more durable materials or are flame retardant. While safer and more functional actuators are generally better, higher durability and safety features generally push up the price of an actuator. If the actuator is used in a demanding environment, then getting the most durable actuator would likely be best; if the environment is minimally demanding, then the user can use his or her discretion on safety issues.
