Festo
188638
Round cylinder DSEU-12-40-P-A-MA
This Festo industrial component, part number 188638, is a double-acting pneumatic cylinder featuring a 12 mm piston diameter, a 40 mm stroke, and an axial supply port with M5 pneumatic connections. Designed with a piston, piston rod, and cylinder barrel structure, it utilizes flexible cushioning rings or plates at both ends and provides position detection for a proximity sensor across an operating pressure range of 1.5 to 10 bar. It operates with dried compressed air, either lubricated or unlubricated, within an ambient temperature range of 0 to 80 °C, and delivers theoretical forces of 68 N on the advance stroke and 51 N on the return stroke at 6 bar.
