Festo
5211905
Round cylinder DSNU-S-12-80-P-A-MQ
The Festo 5211905 is a double-acting industrial component featuring a 12 mm piston diameter, an 80 mm stroke, and an M6 piston rod thread with a structural design comprising a piston, piston rod, and cylinder barrel. It operates on compressed air within a pressure range of 0.15 MPa to 1 MPa (1.5 bar to 10 bar), utilizing elastic cushioning rings at both ends and integrated position sensing via proximity switch. This unit delivers a theoretical force of 67.9 N advancing and 50.9 N retracting at 6 bar, while meeting ISO 14644-1 Class 5 cleanroom suitability and a moderate corrosion resistance class (CRC 2).

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.
