The LAPP 70002752 H07BQ-F spiral cable is designed for mechanical engineering applications requiring a robust, flexible, and high-restoring force connection. Its primary benefit is reliable data and control line use in demanding industrial environments. A potential caveat is its specific voltage and temperature ratings, which must be considered for suitability. Key features include its durable Polyurethane (PUR) outer sheath, a 3-core configuration with a protective conductor, and a 1.5mm² nominal conductor cross-section, extending from 1.5 meters to 4.5 meters.

The nominal voltage (U) is 750V, and the nominal voltage to earth (U0) is 450V. Ensure your application does not exceed these ratings.
The permitted cable outer temperature during assembling and handling is between -25°C and +50°C.
While the PUR sheath offers good durability, specific environmental factors like UV exposure and extreme temperatures should be considered. Refer to the full H07BQ-F specifications for outdoor suitability in your specific conditions.
It means the cable has a strong ability to return to its original, coiled spiral shape after being stretched, ensuring it remains tidy and manageable.
The cable features color-coded cores for easy identification. Typically, one core will be for the protective conductor (ground).
The retracted length is the cable's coiled state (1.5 meters), while the extended length is the maximum it can be safely stretched (4.5 meters).
No, the product description states that the cable is not flame retardant.
Ensure the cable is not obstructed and has not been stretched beyond its 4.5-meter limit. Check for kinks or damage to the spiral. If damage is present, replacement may be necessary.
Verify that all connections are secure at both ends. Check the color-coded core identification to ensure correct wiring. Inspect the cable for any visible damage to the conductors or insulation.
Immediately discontinue use if the PUR outer sheath is significantly cut, abraded, or punctured, as this compromises its protective function and electrical insulation. Inspect internal conductors for damage before considering repair or replacement.
This can occur if the cable is exposed to extreme temperatures outside its rated range or if it has been repeatedly stretched beyond its limit. Allow the cable to return to room temperature and avoid over-extension. If stiffness persists, replacement might be needed.
Setup: Ensure the cable is connected according to the color-coded core identification. The 3 cores are for power/signal, and the core with a protective conductor (typically green/yellow) should be connected to the appropriate ground terminal.
Compatibility: This cable is designed for use within its specified voltage (450V U0 / 750V U) and temperature (-25°C to +50°C during handling) ratings. It is compatible with standard industrial connectors. Verify that the 9mm outer diameter and 3.1cm spiral outer diameter fit your connection points and housing.
Care: To maintain performance, avoid exceeding the maximum extended length of 4.5 meters, as this can permanently damage the spiral structure and reducing its restoring force. Clean the outer sheath with a damp cloth; avoid harsh solvents. Store the cable in a cool, dry place, avoiding excessive bending or stretching when not in use. Regular inspection for any signs of damage to the sheath is recommended.
