Looking for a 650 mm class actuator?
The DF-LA-SL650 is our 650 series. Its datasheet stroke is 635 mm, and that is the figure to design to. We never describe the stroke as 650 mm. If your mechanism needs a different travel, send us the number and we will tell you what an OEM version could look like.
Need a shorter stroke?
The DF-LA-SL250 has a 250 mm stroke and a 7000 N dynamic load.

DF-LA-SL650 questions, answered
Is the DF-LA-SL650 a 650 mm linear actuator?
The DF-LA-SL650 is the 650 series. Its datasheet stroke is 635 mm, so if you need a 650 mm class actuator, check that 635 mm of travel is enough for your mechanism. We do not describe the stroke as 650 mm. For a different stroke, ask about an OEM version.
What is the dynamic load capacity of the DF-LA-SL650?
12000 N (about 1200 kgf), as stated on the Rev A.3 datasheet. Static load is not stated on the datasheet and is confirmed in the quotation.
What motor does the DF-LA-SL650 use?
A 24 V, 240 W BLDC motor with 3 Hall sensors, rated 1.2 Nm at full load. The motor controller is of Dreamfusion's exclusive design.
How fast is the DF-LA-SL650?
6 mm/s with no load and 4 mm/s at full load. At those speeds a full 635 mm stroke takes about 106 s unloaded and about 159 s at full load (calculated from the datasheet speeds, not a measured figure).
What are the mounting ends of the DF-LA-SL650?
An M14 rod end bearing at the front and the rear.
What warranty does the DF-LA-SL650 have?
1 year against manufacturing defects. Misuse, incorrect installation, unauthorised modification or use outside the specifications may void it. See shipping, warranty and returns.
Can I use the DF-LA-SL650 on a solar tracker?
Solar trackers are one of the datasheet's typical applications and our actuators are used on tracker structures. Whether it suits your tracker depends on your load and geometry, so read solar tracker actuator selection and send us your numbers.
