The Cunningham Manufacturing Co. hollow rod servo cylinder is equipped with a Temposonics linear displacement transducer. A permanent magnet is the piston of the cylinder indicates the stroke traveled to as little as +0.002 inch tolerance.

Features

• Frictionless operation of electric parts
• Absolute system - data not lost after power interruption
• Rugged - not affected by adverse conditions
• Direct sensing of position
• Easy installation of a compact package
• High speeds possible with no shock
• Designed for continuous use in mill type application
• Standard Cunningham seal kits and parts

Position Cylinder

• Most NFPA mounts available
• Quick and easy instillation
• Designed for rugged, continuous use
• Standard parts utilized, no special repair procedures
• Internal digital transducer, easily replaced in the field
• Highly accurate (+- .002 inches) repeat positioning
• High forces obtained with high velocity capabilities
• Unaffected by adverse environment conditions, ie., dirt, dust, temperature, humidity, grease, oil, water

Valving/Combinations

• Servo
• Proportional
• Combination servo plus directional
• Proportional plus directional for high speed application where accurate positioning must be maintained
• Valve mounting options (manifold mounting) available

Transducer and Controls

• Internal digital or analog transducer utilizing a magnetostrictive principle
• Output is absolute (no loss of position), infinite resolution, non-contacting, no friction, no wear or deterioration
• Excellent repeatability (zero accumulated error)
• Mechanical stoppage of the cylinder will not affect the system
• Extremely resistant to line noise
• Feedback is an absolute encoder
