Performance Graphs
Speed vs. Load (24V DC): A line graph showing the relationship between load (in Newtons) on the X-axis and speed (in mm/s) on the Y-axis. The performance curve is labeled 'F8' and indicates decreasing speed as load increases.
Current vs. Load (24V DC): A line graph showing the relationship between load (in Newtons) on the X-axis and current (in Amperes) on the Y-axis. The performance curve is labeled 'F8' and indicates increasing current as load increases.
Dimensional Diagram
A detailed diagram illustrating the actuator's physical dimensions and mounting points. Key measurements include an overall length of 420mm when closed and a stroke length of 200mm. The diagram specifies mounting hole diameters (e.g., Ø10mm) and indicates two potential overall lengths, labeled A (388mm) and B (588mm). It also highlights the location of a detachable cable plug.
