STROKE LENGTH: Each type has its range limitations when the actuator’s rod or arm can extend and retract, typically between 50 and 250 millimeters. This is crucial to consider when selecting a linear actuator as it helps ensure that the chosen actuator is suitable for the intended application, considering the required range of motion.  

MOUNTING BRACKETS: Linear actuator mounting brackets come in various types and designs, catering to different applications and preferences: 

• Fork mounting brackets are known for their simplicity and ease of installation. They are suitable for applications where a secure and straightforward attachment is required.  

• Through hole brackets offer flexibility in positioning the actuator and are commonly used in applications where precise alignment or adjustable mounting is necessary.  

REAC supplies linear actuator mounting brackets in a range of dimensions to accommodate different sizes and types of actuators. These dimensions may include variations in width, height, and hole spacing to suit specific requirements. 

CONNECTIONS AND CABLES: Linear actuators, like any electrical component, require appropriate connections and cables for proper operation. The specific type and variant of connections and cables depend on factors such as the type of linear actuator, its intended application, and the environmental conditions. REAC offers numerous variations to suit your application needs. 

FEEDBACK AND LIMIT SWITCHES: Various types of sensors and potentiometers can be integrated into linear actuators to provide feedback or control signals. REAC offers optical sensor encoders, hall sensors over 1 or 2 channels, softpot/linear potentiometers, multi-turn potentiometers, and the DigPot position feedback control system. 

MOTOR VOLTAGE: The most-common DC motor employed with linear actuators is typically 24V, although customization is an option. An advantage of 24V linear actuators lies in their lower current draw compared to 12V. This reduction in current not only leads to cost savings in wiring and electrics but also minimizes losses in a conductor. 

FORCE: Considering the maximum force required in an application is crucial when choosing a linear actuator for several important reasons. This include performance requirements, safety and reliability, avoiding overloading, accommodating dynamic loads, system compatibility, efficiency and energy consumption, cost optimization, and meeting application requirements. 

SPEED: Considering speed requirements is crucial when selecting a linear actuator as it directly impacts the application’s performance, efficiency, and dynamic response. The chosen actuator must align with the desired speed specifications to ensure optimal functionality.Top of Form

POWER CONSUMPTION: Considering power consumption when choosing a linear actuator is crucial due to its direct impact on the efficiency and operational costs of a system. The power requirements of an actuator influence energy consumption, affecting overall system efficiency and sustainability. By selecting an actuator that aligns with specific power constraints and operational needs, one can optimize energy usage, and reduce operating costs. 

BUILT-IN LENGTH AND OTHER DIMENSIONS: What are the limiting measurements in the application? Must the application place the 24V DC motor in any specific position? 

It’s important to recognize that there exists a trade-off among the parameters of force, speed, and power consumption. For instance, opting for a higher speed typically results in a decrease in force and subsequently lowers current consumption. Conversely, choosing higher force generally leads to a reduction in speed, consequently increasing current consumption.
