Festo
189949
Semi-rotary actuator DRE-2-F04-Q08-FO-C
The Festo part number 189949 is a single-acting rack and pinion industrial component featuring an actuator size of 2, a 90-degree swivel angle, and an F04 flange hole pattern conforming to ISO 5211. Operating on compressed air compliant with ISO 8573-1:2010 [7:4:4] within a 2 to 10 bar working pressure range, this unit utilizes spring force for the closing direction and opens via pneumatic supply connected through a G1/8 subbase conforming to VDI/VDE 3845 (NAMUR). Weighing 600 g with a V11 shaft connection, the device has a CRC 4 corrosion resistance classification, requires 1.2 l of air consumption per 0°-90°-0° cycle at 6 bar, and functions across an ambient temperature range of -20 to 80 °C in any assembly position without cushioning or position detection.
