Atlas Copco 4240500201 PF4 Interface Cable – Secure Communication for Power Focus 4

The Atlas Copco 4240500201 (often referred to as 4240500201) is a specialized interface cable designed for the Power Focus 4 (PF4) tightening system. This cable serves as a critical link between the PF4 controller and the electric nutrunner or screwdriver, carrying both control signals and power for the tool. Engineered with high‑quality materials and advanced shielding, the 4240500201 ensures that torque commands and feedback data are transmitted accurately and without interference, even in electrically noisy industrial settings.

Introduction to the 4240500201 Cable

This cable is part of Atlas Copco’s original accessory portfolio, developed specifically to meet the communication requirements of the PF4 platform. Its design emphasizes signal integrity, mechanical robustness, and ease of use. The 4240500201 is suitable for both permanent installations and portable tool trolleys, providing a flexible interconnection that does not compromise performance. The cable’s connector interfaces are keyed to prevent misconnection, ensuring safe and error‑free operation.

These specifications ensure that the cable can handle the full range of PF4 system requirements, from low‑torque precision applications to high‑power fastening tasks.

Design and Construction Excellence

The 4240500201 is built to last. Its PUR jacket provides outstanding resistance to cutting, abrasion, and exposure to oils, coolants, and many industrial cleaning agents. The inner conductors are stranded for flexibility, and the overall cable construction is reinforced with aramid fibers to increase tensile strength. This means the cable can withstand frequent pulling and twisting without suffering internal damage.

The connectors are made from corrosion‑resistant nickel‑plated brass and feature a threaded locking collar that prevents accidental disconnection due to vibration. The contacts are gold‑plated to ensure low‑resistance, long‑lasting connections.

Signal Integrity and Shielding Performance

In Power Focus 4 systems, the communication between controller and tool is digital and time‑critical. Any signal distortion can result in torque errors or loss of traceability. The 4240500201 addresses this with comprehensive shielding: each signal pair is individually foil‑shielded, and the overall cable has a braided shield that covers the entire assembly. This combination attenuates both differential‑mode and common‑mode noise, ensuring that the digital signals remain clean and robust.

The cable’s controlled impedance (120 Ω ± 10%) matches the PF4 bus specification, minimizing reflections and allowing reliable communication over the full 5‑meter length.

Compatibility and Integration

This interface cable is compatible with all Atlas Copco electric tools that support the PF4 interface, including the Tensor ST, Tensor SR, and ETV series. It connects directly to the Power Focus 4 controller’s main tool port and to the tool’s rear connector. The cable also works with PF4‑based multi‑tool systems when used with appropriate distribution modules.

For applications requiring longer distances, Atlas Copco offers extension cables and junction boxes that can be combined with the 4240500201 without degrading signal quality.

Typical Use Cases

• Automotive engine and transmission assembly lines

• Aerospace manufacturing with stringent data logging requirements

• Heavy machinery production – bolting of large structural components

• Precision electronics assembly – where low torque and high accuracy are needed

• Research and development test cells – for tool validation and calibration

Installation Instructions

Installing the 4240500201 is straightforward. Align the connector key with the receptacle on the controller and tool, push firmly, and then tighten the threaded collar by hand until snug. Avoid using pliers or excessive force. The cable should be routed with a minimum clearance of 50 mm from high‑voltage or high‑current lines to reduce potential interference. Use cable ducts or spiral wrap to bundle the cable with other hoses or lines, and ensure that it is not pinched when moving equipment.

Maintenance and Longevity

While the cable is designed for high durability, routine checks are recommended. Inspect the jacket for cuts, cracking, or discoloration, which may indicate chemical attack. Examine the connector contacts for dirt or corrosion, and clean them with a suitable contact cleaner if necessary. If the cable fails any inspection, replace it immediately to avoid production stoppages or quality issues. Atlas Copco provides a comprehensive warranty and rapid spare parts availability.

Safety and Regulatory Compliance

The 4240500201 complies with IEC 60332‑1‑2 for flame retardancy, and it is RoHS and REACH compliant. The cable’s materials are chosen to be free from hazardous substances, and its construction meets the requirements of UL 2586 and CSA C22.2 No. 127. It is designed to operate safely in ambient temperatures up to 85 °C, with a safety margin that covers most industrial environments.

Conclusion

The Atlas Copco 4240500201 PF4 interface cable is a high‑performance, reliable interconnection solution for your Power Focus 4 assembly system. With its excellent shielding, robust mechanical construction, and precise electrical characteristics, it ensures that your tools operate with maximum accuracy and efficiency. Choose the 4240500201 for a dependable connection that supports the demanding requirements of modern manufacturing.
