Festo
1246072
Semi-rotary actuator DFPB-20-090-S5-F04
The Festo 1246072 is a single-acting rack and pinion industrial component featuring an actuator size of 20, an F04 flange hole pattern, and a 90-degree swivel angle without cushioning. Operating at a nominal pressure of 5.6 bar and maximum working pressures up to 8 bar, this unit accommodates any assembly position and includes a NAMUR-compliant VDI/VDE 3845 valve connection without position detection. Certified for hazardous atmospheres with ATEX category II 2G and II 2D ratings, it functions within an ambient temperature range of -20°C to 80°C using ISO8573-1:2010 [7:4:4] compressed air and supports SIL 3 Low Demand mode safety integration.

Request a QuoteWhy 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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
