Festo
190256
Semi-rotary actuator DRE-77-F12-Q14-FO-O
The Festo 190256 is a single-acting rack and pinion industrial component featuring a size 77 actuator with a 90-degree swivel angle and an F12 flange hole pattern conforming to ISO 5211. It operates within a 2 to 10 bar pressure range using dried compressed air, either lubricated or unlubricated, and includes VDI/VDE 3845 NAMUR valve connections alongside an ATEX II 2 GD c X rating for ambient temperatures between -20°C and +60°C. The unit has no position detection or cushioning, provides an end-position adjustment range of -4 to 8 degrees at 0° and -8 to 4 degrees at 90°, features a CRC 3 corrosion resistance classification, and functions in any assembly position with spring-force closing in the opening direction.
