Other Specifications & Diagrams
Product Image: A white linear actuator with a grey protective boot at one end, connected to a white angled housing. The actuator body is cylindrical with a visible screw mechanism at the extended end.
Speed vs. Load Graph (24V DC): This graph illustrates the relationship between actuator speed (mm/s) and applied load (N). The speed decreases linearly as the load increases, reaching approximately 8.2mm/s at a load of 3000N (marked as F8).
Current vs. Load Graph (24V DC): This graph shows the actuator's current draw (A) in relation to the applied load (N). The current increases linearly with load, reaching approximately 2.9A at a load of 3000N (marked as F8).
Dimensional Drawing: The actuator has a main body length of 166mm. The housing width is 84.5mm and height is 49.5mm. Key connection points and mounting holes are indicated with diameters (e.g., Ø10mm). The overall length closed is 320mm. Extended dimensions are provided as A = 288mm and B = 388mm.
Connector Details:
- Front Connector: Features a Ø10mm connection hole with specific mounting dimensions (18mm, 15mm).
- Rear Connector: Features a Ø10mm connection hole with specific mounting dimensions (30mm, 10mm, 14mm, 8mm).
- 4-Pin DIN Plug Pin Out: Details the wiring for the 4-pin DIN connector, showing pins labeled M- and M+. A V-type connector is also depicted.
