CDQ2A32-25DZ: SMC Compact Cylinder, the Compact Drive Specialist for Industrial Automation
2026-01-05
The CDQ2A32-25DZ is a compact cylinder manufactured by Japan’s SMC Corporation, belonging to the CQ2 Z series. Featuring a single-rod, double-acting structure, this cylinder is characterized by a thin, compact design, space-saving form, and built-in magnet. It is widely used in industrial automation control systems, providing precise linear motion solutions for equipment.
Core Product Advantages
- Thin, Compact Design Employs a thin, space-saving, and compact design, significantly reducing installation space requirements. It is ideal for space-constrained applications. Weight is reduced by 5% to 13% compared to the previous generation CQ2 series.
- Multi-Sided Magnetic Switch Mounting Compact magnetic switches can be mounted on four sides (two sides for Φ12 to Φ25). The switches are recessed and do not protrude from the surface, facilitating easy integration into automated control systems.
- Built-in Magnet for Position Detection A built-in magnet (D indicates magnetic type) supports the installation of magnetic switches, enabling real-time piston position detection and high repeatable positioning accuracy.
- Easy Installation Mounting screws are included, and models with rod-end mounting accessories are available. This eliminates the need to separately order cylinders and accessories, improving installation efficiency.

Working Principle
The CDQ2A32-25DZ employs a double-acting cylinder structure. When compressed air enters the cylinder side (IN), the pressure pushes the piston, generating thrust to extend. When compressed air enters the rod side (OUT), the pressure pushes the piston to retract. The reciprocating motion is achieved by controlling the air flow direction via a solenoid valve. The cylinder’s built-in magnet allows for piston position detection in conjunction with magnetic switches. A cushioning device near the stroke ends absorbs impact energy via cushions, decelerating and stopping the piston to prevent or minimize impact against the end covers.
Typical Application Scenarios
- Industrial Automation Production Lines Used in automated production lines such as automotive manufacturing and electronics assembly for tasks like workpiece pushing, positioning, clamping, and transfer, improving production efficiency and product quality.
- Packaging Machinery Controls actions like material conveying, sorting, and marking in packaging machines, enabling flexible grasping and positioning of different materials, ensuring precision and stability in the production process.
- Robotics Serves as a robot’s end-effector, cooperating with the robot arm for tasks like workpiece grasping, positioning, and placement. Precise pressure control allows for soft gripping and collision prevention.
- Precision Manufacturing Equipment Used in semiconductor manufacturing and precision machining equipment to control the action accuracy of pneumatic actuators, ensuring process stability and repeatability, thereby improving product quality.
Installation and Usage Precautions
- Installation Requirements The cylinder should be mounted on a flat, stable base for stable operation. Before installation, ensure the air supply pressure meets the 0.05~1.0 MPa requirement and the air is clean. The piston rod should not be subjected to eccentric or side loads; the load’s motion direction should align with the piston rod axis.
- Operating Environment The operating temperature range is -10~60°C; avoid use in extreme temperatures. Relative humidity should be kept below 90% to prevent moisture-related damage. The operating medium (air) should be filtered through a 40μm or finer filter.
- Regular Maintenance Periodically inspect the cylinder’s connecting pipes and valves for leaks. Keep the cylinder surface clean. Regularly check the cylinder’s operational performance for long-term stability. Apply grease to the cylinder’s sliding surfaces every 6 months.
- Safe Operation Ensure proper equipment grounding before operation. Avoid contact with moving parts during operation. In case of malfunction, stop immediately and consult qualified personnel. Always depressurize the system before installation.
