Working Principle
The CDJ2RA10-95Z-B-M9N utilizes a double-acting cylinder structure. When compressed air enters the rodless side (cap end), the air pressure pushes the piston to extend. When compressed air enters the rod side, the air pressure pushes the piston to retract. The reciprocating motion is achieved by controlling the direction of compressed air flow via a solenoid valve. The cylinder has a built-in magnet, enabling position detection when used with the M9N magnetic switch. The cushioning device decelerates the piston near the stroke ends by forming a sealed air chamber between the cushion plunger and cushion seal, preventing or reducing impact against the cylinder covers.
Typical Application Scenarios
- Electronic Manufacturing Equipment Used in automated production lines for semiconductor manufacturing, electronic device production, etc., for precise actions such as chip placement, micro-component pushing, and PCB board inspection, ensuring high-precision assembly requirements.
- Medical Equipment Used in medical testing instruments, sampling devices, etc., to drive inspection probes, position sampling needles, control valve flaps, meeting the medical industry’s requirements for high cleanliness and high precision.
- Precision Instruments Provides precise linear drive in optical focusing mechanisms, sensor triggering, laboratory automation equipment, ensuring accuracy in measurement and inspection.
- Robot End Effectors Serves as a robot’s end effector, cooperating with robotic arms to achieve workpiece grasping, positioning, and placement, enabling flexible grasping and collision prevention through precise control.
Installation and Usage Precautions
- Installation Requirements The cylinder should be mounted on a flat and stable base to ensure stable operation. Before installation, check that the air supply pressure meets the 0.1~0.7 MPa requirement and ensure the air source is clean. During installation, avoid eccentric or lateral loads on the piston rod. Align the movement direction of the load with the piston rod axis.
- Operating Environment The operating temperature range is -10~60°C. Avoid use in high or low-temperature environments. Relative humidity should be maintained below 90% to prevent moisture from affecting equipment lifespan. The medium used should be filtered through a 40μm or finer filter before use.
- Regular Maintenance Regularly inspect the cylinder’s connecting pipelines and valves to ensure there are no leaks. Periodically clean the cylinder surface to keep it clean. Regularly check the cylinder’s operational performance to ensure long-term stable operation. Apply grease to the cylinder sliding parts every 6 months.
- Safe Operation Ensure the equipment is properly grounded before operation to prevent electric shock hazards. Avoid contact with moving parts during operation to prevent pinching injuries. In case of equipment malfunction, shut down immediately and have it repaired by professionals. Always depressurize before installation to avoid injury from high-pressure media discharge.
