Festo
The Festo 1779435 is a double-acting industrial component featuring a 40 mm piston diameter, a 100 mm stroke, and an M12x1.25 external piston rod end within a profile barrel structural design. Operating on compressed air per ISO 8573-1:2010 [7:4:4] across a 0.6 bar to 12 bar pressure range, this ISO 15552-compliant cylinder achieves a theoretical retracting force of 633 N at 6 bar utilizing self-adjusting pneumatic end-position cushioning. Designed with Class 3 corrosion resistance and ISO 14644-1 Class 5 cleanroom suitability, the unit operates in any mounting position within a -20 °C to 80 °C ambient temperature range while supporting position sensing via proximity switch.
