CE1B32-100 Cylinder: Stroke Reading Cylinder, An Intelligent Feedback Unit with Built-in Displacement Sensor
2026-03-02
Product Positioning
The CE1B32-100 is a stroke reading cylinder from SMC’s CE1 series. It integrates a high-precision displacement sensor within a standard cylinder, enabling real-time detection and feedback of the piston position. This product allows for precise reading of the piston position across the entire stroke with 0.1mm resolution, without the need for external mounting of auto switches or displacement sensors. It is an ideal execution element for achieving精密 positioning, process monitoring, and closed-loop control in automation equipment, widely used in semiconductor manufacturing, electronics assembly, medical devices, and various industrial scenarios requiring precise position feedback.
Core Highlights: Built-in Displacement Sensor, Full Stroke High-Precision Feedback
- Built-in Displacement Sensor for Full Stroke Position Detection
- The sensor unit is integrated within the cylinder, allowing continuous measurement of the piston position throughout the entire cylinder stroke.
- Achieves a resolution of up to 0.1mm and accuracy of ±0.2mm, providing more precise and continuous position feedback information compared to traditional auto switches.
- Arbitrary Origin Setting for Flexible Use
- The origin (zero point) position can be set at any point within the cylinder stroke, eliminating the need to adjust the sensor to the mechanical end. This greatly enhances system design flexibility and on-site commissioning convenience.
- Built-in Magnet Compatible with External Detection
- The cylinder body contains a built-in magnet. Besides using the internal sensor, external auto switches can still be installed as a backup or for auxiliary detection.
- Single Rod, Double Acting Design for Stable Force
- Utilizes a single rod, double acting design, where compressed air drives piston extension and retraction in both directions.
- Bore size Φ32mm, stroke 100mm, theoretical force at 0.5MPa is 402N (extend) / 302N (retract), meeting medium-load precision positioning needs.
- Wide Operating Condition Adaptability, Maintenance-Free
- Operating pressure range 0.05 ~ 1.0 MPa, proof pressure 1.5 MPa, adaptable to various conditions from low-pressure start-up to medium-high pressure drive.
- Piston speed 70 ~ 500 mm/s, ambient temperature 0 ~ 60°C.
- Non-lube type design, pre-lubricated with grease at the factory, requiring no additional oiling during long-term operation, reducing maintenance costs.
- Standard Mounting, Universal Interfaces
- Mounting style is both ends tapped (standard), facilitating fixation to equipment from multiple directions.
- Port thread type is Rc (taper pipe thread), compatible with standard pneumatic connections.
- Comes with a connector (0.5m cable) for easy electrical connection.
- Excellent Anti-Interference Performance
- Through optimized sensor unit design, noise immunity is improved, ensuring stable operation in industrial environments.
