Festo
The Festo 1646744 is a double-acting industrial component featuring a 63 mm piston diameter, a 100 mm stroke, and an M16x1.5 piston rod thread with an external end. Operating within a pressure range of 0.04 MPa to 1.2 MPa (0.4 bar to 12 bar), it utilizes adjustable pneumatic cushioning at both ends across a 22 mm cushioning length, delivers a theoretical retracting force of 1682 N at 6 bar, and conforms to ISO 15552 standards with any mounting position. This unit includes position sensing via proximity switch, operates with compressed air as per ISO 8573-1:2010 [7:4:4], and maintains a moderate corrosion resistance class (CRC 2) within an ambient temperature range of -20 °C to 80 °C.
