Festo
2689551
Hinge cylinder DFAW-50-50-B6-PPSA
This Festo industrial component features a 50 mm piston diameter with a 50 mm stroke and operates via a double-acting mode using compressed air in accordance with ISO8573-1:2010 [7:4:4] at a working pressure of 1 to 10 bar. The unit incorporates self-adjusting pneumatic end-position cushioning (PPS) with a 24 mm cushioning length, integrated flow control valves on both sides for speed regulation, and provisions for position detection via proximity sensors. Structural elements include a piston rod with a male thread and rod clevis, a swivel mounting on the bearing cap, and a cylinder barrel supporting an ambient temperature range of -10 to 60 °C with a CRC corrosion resistance of 0.
