Linear actuator DLP-125- -A
The Festo 125 actuator features a piston diameter of 125 mm, a stroke ranging from 40 to 600 mm with a 2 mm stroke reserve, and a double-acting mode of operation. Conforming to DIN 3358 and VDI/VDE 3845 NAMUR standards, this piston rod design supports proximity sensors for position detection and operates within a pressure range of 0.2 to 0.8 MPa (2 to 8 bar / 29 to 116 psi) at a nominal working pressure of 0.6 MPa (6 bar / 87 psi). Certified for hazardous locations under ATEX category II 2G gas and UK EX instructions in compliance with the EU-Ex protection guideline, this unit has no cushioning and allows any assembly position.
