Semi-rotary actuator DRE-77-F12-Q12-FO-O-PS

The Festo 561978 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. Designed with no cushioning and no position detection, this unit operates on compressed air meeting ISO 8573-1:2010 [7:4:4] standards at a working pressure range of 2 to 10 bar, with a valve connection conforming to VDI/VDE 3845 (NAMUR) and a corrosion resistance classification of CRC 3. Certified for hazardous locations under ATEX category II 2G for gas (c T6) and II 2D for dust (c 60°C) within an ambient temperature range of -20°C to +60°C, it supports any assembly position and allows lubricated operation subsequently required for further operation.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
