Description
The Festo standards-based cylinder DSNU-20-12-P-A is double-acting with a piston Ø of 20 mm and 12 mm stroke and pushes with 188.5 N at 6 bar. The end positions can be sensed with proximity switches.
Benefits
- Theoretical force at 6 bar: 188.5 N advance, 158.3 N return
- Piston Ø 20 mm and stroke 12 mm, defined by the order code DSNU-20-12-P-A
- Conforms to CETOP RP 52 P, ISO 6432, standard mounting accessories fit
- Elastic cushioning rings at both ends (P), permissible impact energy 0.20 J
- Cylinder barrel and piston rod in high-alloy stainless steel
- Prepared for proximity switches to sense the end positions (code A in the type)
Applications
The DSNU-20-12-P-A suits stopping, sorting and feeding tasks where 12 mm stroke and a piston Ø of 20 mm are sufficient. The M8 piston rod thread on the DSNU-20-12-P-A takes the matching rod-end accessories. For replacement please compare the type DSNU-20-12-P-A with the installed cylinder.
