Product Information

Full details

This Festo EV-20/75-5 clamping module is designed for technical environments requiring precise, consistent clamping. Its key benefit is reliable, space-efficient operation for securing components against a stop. A potential caveat is its specialized nature, requiring understanding of pneumatic systems for optimal use. This rodless module features a 20x75 mm clamping area, a 5 mm stroke, and a single-acting mechanism with a reset function, all housed in a flat, space-saving design.

Extended Product Information

FAQs

What is the clamping force of the EV-20/75-5 module?

The specific clamping force depends on the applied air pressure. Consult the technical datasheet for precise force calculations based on pressure.

Can this module be used for continuous clamping without reset?

The EV-20/75-5 is a single-acting module designed for clamping and then resetting. Continuous clamping without cycling might not be its intended use and could lead to premature wear.

What type of compressed air should I use?

It is recommended to use clean, dry, and sometimes lubricated compressed air, depending on the specific requirements of the diaphragm and seals. Refer to the Festo guidelines for optimal air quality.

What is the maximum operating pressure?

The maximum operating pressure should be referenced from the official Festo technical documentation for the EV-20/75-5 model to ensure safe and reliable operation.

How is the 'clamping against a stop' feature beneficial?

This design ensures highly accurate and repeatable positioning of the workpiece, as it relies on a fixed reference point for final placement, crucial for precision tasks.

Is this module suitable for harsh environments?

The hermetically sealed system offers good protection against contaminants, making it suitable for many industrial environments. However, extreme conditions should be evaluated against the product's material specifications.

Troubleshooting

Module does not clamp

Verify pneumatic air supply is connected and pressurized. Check control valve operation and air line integrity. Ensure the clamping surface is clear.

Module does not reset (unclamp)

Check for obstructions preventing retraction. Inspect the reset mechanism (e.g., spring) for damage or wear. Ensure adequate air pressure for reset if it's pneumatically assisted.

Inconsistent clamping force

Check air pressure stability. Inspect the diaphragm for damage or leaks. Ensure the clamping surfaces are clean and the stop is rigid.

Air leaks from the module

Inspect seals and the diaphragm for damage. Ensure all pneumatic connections are secure. If leaks persist, the module may require servicing or replacement.

Pros and Cons

Pros

  • Space-saving flat design is ideal for confined applications.
  • Provides consistent and precise clamping force.
  • Durable construction with a sealed pressure chamber for reliability.
  • Simple, single-acting mechanism reduces complexity.
  • Suitable for automated processes requiring repeatable positioning.

Cons

  • Requires a pneumatic air supply and control system.
  • Stroke length is fixed at 5 mm, limiting application flexibility.
  • Primarily designed for clamping against a stop, not for general movement.
  • May require specialized knowledge for integration and maintenance.
  • Not suitable for applications requiring very high clamping forces beyond its specification.

Setup, Compatibility & Care

Setup

  1. Pneumatic Connection: Connect a clean, dry, and lubricated compressed air supply (if required by your system) to the appropriate port on the module. Ensure the pressure meets the module's operating specifications.
  2. Mounting: Securely mount the module to your machine frame or fixture using appropriate fasteners. The flat profile allows for versatile mounting options.
  3. Actuation Control: Integrate the module into your control system, typically via pneumatic valves, to manage the clamping and reset functions.

Compatibility

  • Requires a compatible pneumatic control system (valves, air lines).
  • Ensure the operating pressure range is compatible with your plant's compressed air system.
  • The module is designed for clamping against a rigid stop; ensure your application provides this.

Care

  • Regularly inspect air lines for leaks and damage.
  • Monitor the pneumatic air quality; contamination can affect diaphragm performance.
  • Keep the clamping surfaces clean from debris to ensure optimal contact.
  • Avoid exceeding the specified operating pressure or stroke limits.
