Festo
557627
Semi-rotary actuator DFPB-270-090-S5-F1012
The Festo size 270 single-acting rack and pinion industrial component operates via compressed air in accordance with ISO8573-1:2010 [7:4:4] at a working pressure of 8 bar or less and a nominal working pressure of 5.6 bar. Featuring a 90-degree swivel angle, an F1012 flange hole pattern, a NAMUR-standard valve connection, and SIL 3 Low Demand mode safety integrity, this un-cushioned unit operates in any assembly position within a -20 to 80 degrees Celsius ambient temperature range. It carries ATEX category II 2G and II 2D ratings with explosion-proof protection types c T4 X and c 125°C X for environments from -20°C to +80°C, supporting lubricated operation when subsequently required.
