The example CDUK6□30D-A93□ specifies a magnetic, non-rotating cylinder with 6mm bore, 30mm stroke, double-acting operation and A93 switch; square placeholders indicate option positions. W and KW double-rod configurations are excluded from single-acting and long-stroke selections.
| Parameter | Specification |
|---|---|
| Medium | Air |
| Maximum operating pressure | 0.7MPa |
| Ambient and air temperature without switch | -10–70°C, nonfreezing |
| Ambient and air temperature with switch | -10–60°C, nonfreezing |
| Cushioning | Rubber cushions at both ends |
| Piston speed | 50–500mm/s |
| Stroke tolerance | 0 to +0.1mm |

Values are in MPa. Match both action and rod configuration; a shared bore does not give all versions the same starting pressure.
| Action | Rod configuration | 6mm bore | 10–16mm bore | 20–32mm bore |

For spring-return operation, air extends the rod and the spring retracts it. For spring-extend operation, air retracts the rod and the spring extends it. Select magnetic switch model and quantity separately from the cylinder action and stroke.
