Semi-rotary actuator DRE-880-F25-Q10-FS-C

The Festo 189844 is a single-acting rack and pinion industrial component featuring an actuator size of 880, a 90-degree swivel angle, and an ISO 5211 conforming F25 flange hole pattern with a VDI/VDE 3845 NAMUR valve connection. Operating on compressed air in accordance 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 without cushioning or position detection, and can be mounted in any assembly position. Certified with the CE symbol according to the EU-Ex protection guideline, it is rated for ATEX category II 2G gas with c T6 ignition protection and ATEX category II 2D dust with c 60°C ignition protection across an explosion-proof ambient temperature range of -20°C to +60°C.

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.
