The Parker ETT Electric Tubular Motor

The Parker ETT Electric Tubular Motor is a cost-effective, energy-efficient alternative to pneumatic cylinders. The ETT is ideal for applications requiring greater flexibility and control.
Parker ETT


The ETT electric tubular motor from Parker is a direct thrust linear motor actuator, ideally suited as a replacement or alternative to pneumatic cylinder in wide variety of linear handling and pick & place applications.

The ETT’s linear motion is directly generated and free from ball screws, belts and/or gearboxes/gears and associated problems.

The IP67 protection class makes the ETT tubular motor suitable for use in harsh environmental conditions.

The ETT combines the functionality of a linear motor, an electric cylinder and a pneumatic cylinder and is ideal for applications where these products are frequently used.

Suitable for used in a wide range of applications:

The ETT is perfect for packaging applications, material handling, food, pharmaceutical & beverage and factory automation.


  • Simple mechanical integration.
  • Flexible mounting.
  • High energy efficiency and reduced maintenance.
  • Improved reliability and increased mechanical life.
  • Used in “clean” environments.
  • Fewer mechanical components.
  • Reduced installation costs.
  • Excellent control and dynamic positioning.
Parker ETT
  • Rod: Stainless steel AISI 304 shaft with NdFeB magnets, available in 3 different diameters 12,16 and 25 mm.
  • Coil: Class H motor coils, with three-phase standard brushless design with 1000 V of winding insulation.
  • Feedback: Sin/Cos analogue feedback 1 Vpp as standard. Other types of feedback like BISS-C, digital A/B TTL line-drive incremental are also available.
  • Connectivity: Single rotating connector for power and position feedback except sizes 32 and 50, which have 2 separate connectors.
    The smallest frame size has flying leads.
