|---|---|---|---|---|---|---|---|---|
| Explanation: |
Series SDA - Compact double-acting cylinder; this example uses the standard SDA construction. |
Bore 12 - 12mm |
Stroke 50 - 50mm stroke in the displayed 50mm-bore configuration; select an available stroke for the chosen bore. |
Magnet Blank - Without magnet; omit S and its separator |
Rod End Blank - Female thread; omit rod-end suffix and its separator |
SDA compact cylinders provide short-body pneumatic actuation with selectable bore, stroke, magnetic piston and rod-end connection. The family includes double-acting, double-rod, adjustable-stroke and single-acting configurations; choose the action type before applying operating ratings.
| Code | Configuration |
|---|---|
| SDA | Compact double-acting cylinder |
| SDAD | Double-rod cylinder |
| SDAJ | Adjustable-stroke cylinder |
| SSA | Single acting: air extends the rod, spring retracts it |
| STA | Single acting: air retracts the rod, spring extends it |
| SDAT | Duplex configuration |
| SDAW | Duplex-end configuration |
| Ordering field | Selection |
|---|---|
| Bore × stroke | 50×50 denotes 50mm bore × 50mm stroke |
| Magnet | Blank: without magnet; S: with magnet |
| Rod end | Blank: female thread; B: male thread; N: unthreaded |
SDA50x50-S-B specifies a double-acting compact cylinder with 50mm bore, 50mm stroke, magnetic piston and male-thread rod end. SSA and STA single-acting selections cover 12–63mm bores; their action and operating requirements must be selected separately from the double-acting ratings below.
