Festo
544426
Linear actuator DGCI-25- -
The Festo 544426 is a double-acting industrial component featuring a piston diameter of 25 mm and a stroke range from 100 mm to 2000 mm, applicable for servopneumatic positioning and Soft Stop operation with a stroke reduction of 25 mm in the end positions. Equipped with a recirculating ball bearing guide and an attached linear potentiometer for position sensing, it operates within an operating pressure range of 0.2 MPa to 0.8 MPa (2 bar to 8 bar, 29 psi to 116 psi) using pneumatic shock absorbers with hard or soft characteristic curves. This unit carries RCM, CE, and UKCA markings, holds ATEX and UKEX explosion protection certifications for Zone 2 gas (II 3G) and Zone 22 dust (II 3D), and supports mounting in any position with optional variants including an axis clamping unit and additional slides.
