Festo
561381
Linear actuator DFPI-125- -ND2P-C1V-P
This Festo industrial component, part number 561381, is a double-acting piston rod and cylinder barrel assembly featuring a 125 mm piston diameter, an F10 flange hole pattern, a 3 mm stroke reserve, and an adjustable stroke ranging from 40 to 990 mm based on the DIN 3358 standard. Operating at a nominal working pressure of 6 bar within a 3 to 8 bar working range, it achieves a maximum advancing speed of 0.049 m/s and a maximum retracting speed of 0.048 m/s, utilizing a 24 VDC nominal operating voltage within a 21.6 to 26.4 V range. The unit includes a potentiometer displacement encoder for position detection alongside a proximity sensor, is polarity protected for operating voltage, set point value, and initialization connection, offers no cushioning, supports any assembly position, and is rated for C1 weather protected outdoor locations of use.
