Product Information

Full details

The LAPP ÖLFLEX 400 P Spiral Cable is designed for professionals in machine building, mechanical engineering, and automation systems who require a durable, flexible, and resilient control and power cable. Its key benefit is its high restoring force and the ability to extend up to three times its closed length, offering great maneuverability in tight spaces. A potential caveat is its specific temperature range for flexing, which needs to be considered in extreme environments. This PUR spiral cable features a grey sheath, bare copper wires, and special PVC core insulation, providing high resistance to chemicals, oils, and abrasion.

Extended Product Information

FAQs

What is the maximum extension length of this spiral cable?

The cable has an expansion ratio of 3:1, meaning a 500 mm closed length can be extended to 1500 mm.

What type of insulation material is used for the cores?

The cores are insulated with special PVC P8/1.

Is this cable suitable for outdoor use?

Yes, the cable is UV resistant, making it suitable for many outdoor applications, provided it stays within its specified temperature range.

What is the operating temperature range for flexing this cable?

The cable is designed for flexing within a temperature range of 5°C to 50°C.

What does 'high restoring force' mean for this cable?

It means the cable has a strong tendency to return to its original coiled shape after being stretched, ensuring reliable retraction.

Can this cable be used for high-frequency signals?

This cable is specified as a control and power cable; for high-frequency applications, specific shielded data cables might be more appropriate.

How resistant is the PUR sheath to different chemicals?

The PUR sheath offers high resistance to benzols, benzines, and other substances listed in Appendix T1 of the LAPP specifications.

Troubleshooting

Cable does not retract fully

Ensure the cable is not caught on any obstructions and that it has not been extended beyond its maximum 3:1 ratio. Check for any kinks or permanent deformation in the spiral.

Intermittent signal loss or power failure

Inspect the drawn ends for secure connections. Check the core insulation for any damage. Ensure the cable is within its operational temperature range and has not been exposed to excessive chemicals or abrasion.

Sheath appears damaged or degraded

If the PUR sheath shows signs of chemical attack or abrasion, the cable may need replacement. Avoid exposing the cable to unlisted chemicals or abrasive surfaces.

Pros and Cons

Pros

  • Excellent flexibility and retraction due to spiral design.
  • High resistance to chemicals, oils, and abrasion enhances longevity.
  • Suitable for dynamic applications requiring frequent extension and retraction.
  • Compact size is advantageous for space-constrained machinery.
  • UV resistance extends its usability in various environments.

Cons

  • Specific flexing temperature range (5-50 °C) may limit use in extreme cold or heat.
  • Fixed cable lengths and drawn end lengths require careful planning.
  • Not designed for permanent immersion in oils.
  • Requires careful handling to avoid damage to the spiral structure if overextended beyond its limits.

Setup, Compatibility & Care

Setup: The ÖLFLEX 400 P spiral cable comes with pre-determined drawn ends for connection. Ensure that the connection points are clean and compatible with the cable's conductor specifications (5G0.75 mm²).

Compatibility: This cable is designed for use as control and power cables within machines and mechanical engineering, particularly in automatic control systems. It is compatible with standard industrial connectors and termination methods suitable for 0.75 mm² conductors.

Care:

  • Avoid exposing the cable to temperatures outside the flexing range of 5°C to 50°C for prolonged periods.
  • Ensure the cable is not pulled beyond its 3:1 expansion limit to prevent damage.
  • Clean the cable sheath with a damp cloth. Avoid harsh solvents that could degrade the PUR material.
  • Regularly inspect the cable for any signs of abrasion or damage, especially at connection points.
