High-torque industrial cylinder with integrated magnetic field for sensor mounting (STC suffix indicates built-in magnet). Features anti-rotation design and IP66 protection rating. Requires 40μm filtered compressed air with max 1.5m/s piston speed for optimal lifespan (3,000km minimum).
- Metal stamping press ejection systems
- Automotive welding fixture positioning
- Packaging machine clamping mechanisms
- Plastic injection molding machine core pulls
- Conveyor gate actuators in food processing
Installation note:
Mounting axis alignment must be within ±0.5° angular deviation.
For vertical installations, use counterbalance valves. Magnetic
sensor positioning requires 2mm gap adjustment during commissioning.
