561690

Name: Festo 561690 Semi-rotary actuator DSMI-25-270-A-B
Brand: Festo

Semi-rotary actuator DSMI-25-270-A-B

The Festo part number 561690 is an industrial component featuring a rotary vane design structure with a ball-bearing drive shaft, a 25 mm piston diameter, and a swivel angle range of 0 to 272 degrees with a 0 to 270 degree rotation angle adjustment range. Operating at a working pressure of 4 to 8 bar (0.2 to 1 MPa), it achieves a maximum swivel frequency of 2 Hz at 0.6 MPa, travel speeds between 50 deg/s and 2,000 deg/s, and incorporates flexible cushioning rings/plates at both ends alongside an integrated analog displacement encoder for position detection.
