1. Patented crank-slider mechanism (constructed with high-strength, wear-resistant materials): a) Ensures structural stability and generates exceptional clamping force with minimal air pressure through high mechanical efficiency. b) Integrated self-locking mechanism maintains clamping force even during air supply interruption.
2. DIN-compliant four-side mounting configuration for flexible installation options.
3. Monolithic design integrating clamping mechanism with pneumatic cylinder for enhanced structural integrity.
4. Specially engineered sensor bracket with anti-spatter design and ±15° adjustable angles, featuring anti-interference shielding for stable signal transmission.
5. Space-efficient oval-shaped cylinder housing optimizes equipment layout in confined spaces.
6. Modular clamp arms (AM1/AM2/AM3/AM4) with R/C/L variants (radial/vertical/lateral orientations) adapt to diverse operational demands.
7. Tool-free opening angle adjustment via replacement of adjustment screws (15°-180° range).

The hexagonal body design prevents rotation during operation. Requires 5μm filtered air with ISO VG32 lubricant (optional oil-free operation available).
- Robotic welding fixture systems
- Automotive chassis assembly jigs
- High-frequency spot welding machines
- Forging press positioning clamps
- Battery pack compression welding
 Installation guidelines: 
            Maintain parallel alignment between cylinder axis and workpiece surface. 
            Use DIN 65226L washers for vibration resistance. 
            Lubricate every 500,000 cycles under normal load conditions.
