FestoDSNU 12 160 P ARound Pneumatic Cylinder, ISO 6432, 12 mm Bore, 160 mm Stroke, Double-Acting, Magnetic Piston, Elastic Cushioning

Product Description

What this part is: Festo DSNU-12-160-P-A, Festo order number 19196, a double-acting round pneumatic cylinder to ISO 6432. Piston Diameter: 12 mm. Stroke: 160 mm. Overall Length: 265 mm. Pneumatic Connection: M5. Piston Rod Thread: M6, male. Operating Pressure: 1 to 10 bar. Cushioning: elastic cushioning rings and plates at both ends. Position Sensing: magnetic piston, via proximity switch. Mounting Position: any. Product Weight: 139 g. Decoding the designation: DSNU — Festo’s round cylinder family to ISO 6432, with a stainless steel cylinder barrel and wrought aluminium alloy bearing and end caps. 12 — piston diameter in millimetres. 160 — stroke in millimetres. P — elastic cushioning rings and plates at both ends. A — with position sensing. The piston carries a magnet, so the stroke ends can be picked up by proximity switches clamped to the barrel. What these specs mean in practice: Theoretical Force at 6 bar, Advancing: 68 N. Theoretical Force at 6 bar, Retracting: 51 N. The difference is the area the piston rod takes out of the annulus on the return side, and it is why a DSNU of this size is specified on the extend stroke. Impact Energy in the End Positions: 0.07 J. Elastic cushioning is a fixed polymer element, so there is no cushioning screw to set — the energy figure is the ceiling the cushioning will absorb at each end. Moving Mass at 0 mm Stroke: 18.5 g. Operating Medium: compressed air to ISO 8573-1:2010 [7:4:4]. Lubricated operation is possible, and once a DSNU has run lubricated it stays on lubricated air. Ambient Temperature: −20 to +80 °C. Design: piston, piston rod and cylinder barrel. Conforms to Standard: ISO 6432, and to CETOP RP 52 P. Approvals: ATEX II 2GD and Germanischer Lloyd. Mounting data: Overall Length at 160 mm Stroke: 265 mm. Body Length at 0 mm Stroke: 105 mm. Pneumatic Connection: M5, both ends. Piston Rod Thread: M6 male. Mounting Position: any. Mounting is by accessory — flange, foot, swivel, rear and front clevis brackets all fit the ISO 6432 envelope for a 12 mm piston. Position sensing uses Festo proximity switches clamped to the round barrel. A cylinder with position sensing needs a minimum 10 mm stroke for reliable sensing, and this one is at 160 mm. Quantity and configuration: Unit Quantity: 1 Pc. Cylinder only. Interchange guidance: DSNU-12-160-P is the same cylinder without the magnetic piston, so it will fit the same brackets but will not trigger a proximity switch. DSNU-12-160-PPV substitutes pneumatic cushioning adjustable at both ends for the elastic rings. ESNU-12-160 is the single-acting spring-return version on the same ISO 6432 envelope. Any ISO 6432 12 mm cylinder matches on mounting interface, M5 ports and M6 rod thread, so the decisive differences between makers are the cushioning type, the presence of a magnet, and the barrel material.
