Festo
189454
Mini guided actuator DFC-4-20-P-GF
The Festo part number 189454 is a double-acting industrial component featuring a 4 mm piston diameter, a 20 mm stroke, and a yoke drive unit operating within a pressure range of 0.35 MPa to 0.7 MPa. Equipped with elastic cushioning rings at both ends, a sliding guide, and a designated centre of gravity distance xs of 5 mm, this unit supports a maximum payload of 1.7 N and a maximum speed of 1 m/s across any mounting position. It operates using compressed air conforming to ISO 8573-1:2010 [7:4:4] within an ambient temperature range of -5 °C to 60 °C, achieving a moderate corrosion resistance class of CRC 2 and VDMA24364-B2-L LABS conformity.
