Humphrey Cylinder HTDA-6×1/2
Humphrey, an American manufacturer specializing in the research and development of pneumatic components, is renowned for its cylinders featuring high-precision signal control, compact structures, and strong environmental adaptability. These cylinders are widely applied in engine testing, automated production lines, and precision equipment.
Core Design Features
Integrated Signal Feedback System
• Magnetoelectric Position Sensing: The cylinder incorporates a built-in magnetoelectric sensor that generates alternating electromotive force signals (G1/G2 signals) through changes in the air gap between the rotor flange and the magnetic head, providing real-time feedback of the piston position to the control system with a positioning accuracy of ±0.1mm.
• Anti-interference Capability: Employing electromagnetic shielding design, it withstands high-frequency vibrations and electromagnetic interference in industrial environments, with a signal stability error of less than 2%.
Structural Optimization and Material Processes
• Compact Cylinder Body: Constructed from integrated aluminum alloy casting with surface hardening treatment (hardness ≥ HRC45), it reduces weight by 30% while maintaining high compressive strength (withstanding pressure ≥ 1.2MPa).
• Dual Sealing System: The piston rod is equipped with dual Y-shaped polyurethane seals, supporting dry operation and low-lubrication conditions, with a dust protection rating of IP67 and an applicable temperature range of -20℃ to +80℃.
• Modular Interface: Supports ISO 15552 standard flange mounting and offers SAE/UNF threaded interface options, accommodating various pneumatic connection requirements.
Motion Control Performance
• Low-Friction Guidance: The piston rod is hard chrome-plated and paired with self-lubricating bearings, achieving a starting pressure of ≤0.05MPa and an idle speed of up to 500mm/s.
• Cushioning Design: Incorporates an adjustable pneumatic cushioning device to reduce impact forces at the end of travel, with a repeat positioning accuracy of ±0.05mm.
