Festo
544425
Linear actuator DGCI-18- -
The Festo part number 544425 is a double-acting industrial component featuring an 18 mm piston diameter, an operating pressure range of 0.2 MPa to 0.8 MPa (2 bar to 8 bar / 29 psi to 116 psi), and a stroke length adjustable from 100 mm to 2000 mm with a 20 mm stroke reduction in the end positions. Equipped with a recirculating ball bearing guide, pneumatic shock absorbers with hard and soft characteristic curves, and an attached linear potentiometer for position sensing, this model operates in any mounting position and includes variants with a protected guide or additional left and right standard slides. Certified for ATEX and UKEX Zone 2 and Zone 22 hazardous locations with II 3G gas and II 3D dust categories, it carries RCM compliance, CE marking, and UKCA marking per applicable EMC, explosion protection, and RoHS directives.
