Name: Festo 557542 Semi-rotary actuator DFPB-45-090-F05
Brand: Festo

Semi-rotary actuator DFPB-45-090-F05

This Festo industrial component, part number 557542, is a double-acting rack and pinion actuator featuring a size 45 footprint, an F05 flange hole pattern, and a 90-degree swivel angle without cushioning or position detection. The unit operates within a working pressure range of 1 to 8 bar at a nominal pressure of 5.6 bar using compressed air conforming to ISO 8573-1:2010 [7:4:4], allowing for lubricated operation that is subsequently required for further use in any assembly position. Certified for hazardous locations, it meets ATEX category II 2G for gas with c T4 X protection and category II 2D for dust with c 125°C X protection, supporting ambient operating temperatures from -20°C to 80°C and Safety Integrity Level (SIL) up to SIL 3 in Low Demand mode with a NAMUR VDI/VDE 3845 standard valve connection.
