Cylinder Magnetic Sensors
Cylinder magnetic sensors (Magnetic Proximity Sensors for Cylinders) are typically used together with cylinder pistons equipped with a magnetic band. An internal permanent magnet is embedded in the piston rod or piston. When the piston moves to the sensor’s position, the magnetic field influences the sensing element (such as a Reed Switch or Hall Sensor) to generate a switching signal. Output is usually binary (ON/OFF), while some advanced models can provide analog signals for position determination.
I. Principle of Cylinder Magnetic Sensors
Internal Structure: A permanent magnet is embedded in the piston rod or piston.
Detection Method: When the piston reaches the sensor’s position, the magnetic field affects the sensing element, producing a switching signal.
Output Characteristics: Typically ON/OFF output; some models offer analog output to determine position.
II. Common Types
1. Reed Switch Type: Low cost and simple structure; disadvantage is lower impact resistance and limited service life.
2. Hall Effect Sensor: No mechanical contact, vibration-resistant, long lifespan, and capable of high-frequency operation.
III. Installation Position
Typically mounted in the sensor slot along the cylinder body, aligned with the piston stroke. The sensor can be positioned at any point along the stroke to detect end position, intermediate position, or home position.
IV. Application Range
1. Position Detection: Confirms whether the piston has reached a designated position (e.g., fully extended or fully retracted) for position confirmation in automated lines.
2. Stroke Control: Works with PLCs or controllers for sequential operations—for example, the next process starts only after the piston reaches the target position.
3. Safety Interlock: Detects whether a workpiece is properly clamped or positioned to prevent malfunctions.
4. Machining Equipment: In CNC fixtures and automated jigs, detects whether clamps or jaws are closed; in packaging and material handling equipment, verifies completion of cylinder motion.
5. Logistics and Handling: Confirms actions in sorting, pushing, or positioning modules.
6. Other Examples: Automotive production lines (clamp or lift platform position detection) and food/pharmaceutical packaging (high-frequency, fast detection applications).
Hydraulic Sequence Valve
A hydraulic sequence valve is a type of pressure control valve, used to ensure that multiple actuators in a hydraulic system (such as cylinders or hydraulic motors) operate in a preset sequence according to pressure settings.
Working principle: When the hydraulic pressure in the line reaches the set value, the sequence valve opens, allowing oil to flow to the next circuit and activating the subsequent actuator.
Main function: To achieve sequential operation of multiple actuators with a single hydraulic power source.
Features
• Enables one pump to drive multiple cylinders sequentially.
• No additional electrical control required; sequence is determined purely by pressure.
• Simplifies circuit design and control systems.
Applications
1. Machining Fixtures — Activate the positioning cylinder first, then the clamping cylinder, ensuring the workpiece is positioned correctly before clamping.
2. Molding / Die Casting Equipment — Mold closing → pre-pressing → high-pressure locking, ensuring proper processing quality by sequential action.
3. Presses / Punching Machines — Sequence valves control multi-stage pressing actions, e.g., fast advance followed by slow pressing.
4. Handling / Lifting Mechanisms — Ensures the platform is lifted before locking, or safety devices are released before cylinder activation.
5. Hydraulic System Safety Control — Prevents multiple actuators from moving simultaneously, avoiding interference or hazards.
Example
Suppose a hydraulic fixture requires the sequence “positioning → clamping”:
• The pump supplies oil simultaneously to both the positioning cylinder and the clamping cylinder.
• The positioning cylinder’s circuit has no sequence valve, allowing it to move first.
• The clamping cylinder’s circuit is equipped with a sequence valve set to a higher pressure than the positioning cylinder.
Once the positioning cylinder completes its stroke and back pressure builds up, the system pressure rises to the valve’s set value → the valve opens → oil flows into the clamping cylinder → completing the required sequence.
Air Drive Hydraulic Power Unit
A air drive hydraulic power unit is a device that uses compressed air to generate high-pressure hydraulic oil. By driving a hydraulic piston with a pneumatic cylinder, it converts low-pressure air energy into high-pressure hydraulic energy. Through the principle of hydraulic intensification (pressure ratio), it can generate hydraulic pressure many times higher than the input air pressure, without the need for a large hydraulic pump. Typical input air pressure: 5–8 bar; output hydraulic pressure: 50 bar to 350 bar or even higher.
Main Components
1. Pneumatic Drive Module – driven by compressed air.
2. Hydraulic Intensifier Cylinder – converts pneumatic force into hydraulic pressure.
3. Oil Reservoir – stores hydraulic oil.
4. Control Valve Set – includes directional control valve, check valve, and relief valve.
5. Pressure Switch / Sensor (optional) – monitors output hydraulic pressure.
Features
• High Pressure Output: Small pneumatic input produces high hydraulic output.
• Compact and Simple Structure: Eliminates the need for a traditional hydraulic pump and motor.
• Safe Operation: Operates only with compressed air, reducing electrical hazards.
• Easy Maintenance: Modular design of pneumatic and hydraulic components.
• High Energy Efficiency: Consumes air only during operation.
Applications
1. Clamping Fixtures / Jigs: Used with hydraulic cylinders in CNC machining or automated fixtures. Example: workpiece positioning → high-pressure hydraulic clamping.
2. Press-Fitting / Assembly Processes: Provides high pressure for press-fitting, riveting, and assembly operations.
3. Mold Operation: In plastic, die-casting, or stamping molds, drives small hydraulic cylinders for ejection, release, or locking.
4. Testing Equipment: Supplies high-pressure oil for pressure resistance and leakage testing.
5. Handling / Gripper Mechanisms: Provides stable thrust through hydraulic cylinders for automated handling.
Typical Example
In an automated fixture system: The compressed air system provides 6 bar air pressure → supplied to the pneumatic-hydraulic power unit. The unit converts this into 150 bar hydraulic pressure → delivered to the hydraulic cylinder. The hydraulic cylinder then performs clamping, pressing, or ejecting operations.
Advantages Compared
Compared with pure pneumatic systems: Can deliver higher thrust and more stable operation.
Compared with pure hydraulic systems: No motor or large oil tank required → simpler system and lower cost.
