DF-LA-SL250 questions, answered
What is the dynamic load capacity of the DF-LA-SL250?
7000 N (about 700 kgf), as stated on the Rev A.3 datasheet. Static load is not stated on the datasheet and is confirmed in the quotation.
What stroke does the DF-LA-SL250 have?
250 mm. For the longer 635 mm stroke at 12000 N, see the DF-LA-SL650 (650 series).
What motor does the DF-LA-SL250 use?
A 24 V, 120 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-SL250?
6 mm/s with no load and 4 mm/s at full load. A full 250 mm stroke therefore takes about 42 s unloaded and about 63 s at full load (calculated from the datasheet speeds).
What are the mounting ends of the DF-LA-SL250?
A DIA14 square connector with an adjustable hole at the front and the rear.
Is the picture of the DF-LA-SL250 a photograph of the product?
No. The image is labelled illustrative. The specifications come from the datasheet. Drawing dimensions marked * on the actuators page are derived and being verified, so confirm them in the quotation.
What warranty does the DF-LA-SL250 have?
1 year against manufacturing defects. See shipping, warranty and returns for what is and is not covered.
