Atlas Copco PF4 Tool Cable 5M ST – Straight Connector Cable for Power Focus 4 Systems

The Atlas Copco PF4 Tool Cable 5M ST, identified by part numbers 4220 2636 05 and 4220263605, is a high‑grade interconnection cable specifically designed for the Power Focus 4 (PF4) platform. This 5‑meter cable features a straight (ST) connector configuration, making it a versatile and practical choice for a wide range of assembly stations. It is engineered to deliver both the electrical power and the high‑speed communication signals required for precise, torque‑controlled fastening operations in modern manufacturing.

Product Overview

This PF4 tool cable is an original Atlas Copco accessory, manufactured to the same stringent quality standards as the controllers and tools it connects. The 5‑meter length provides ample reach to connect the tool to the controller cabinet while maintaining optimal signal integrity. The straight connector eliminates the need for awkward bends and allows the cable to be routed neatly along machine frames or through cable carriers. Its robust construction ensures reliable performance even in high‑stress environments where the cable is subject to continuous flexing and pulling.

Mechanical and Ergonomic Features

The 5M ST cable is designed to minimize operator fatigue. Its TPE jacket is exceptionally flexible, even at low temperatures, reducing the force needed to move the tool around the workstation. The cable’s smooth surface reduces friction against edges and prevents kinking. The straight connector is lightweight and features a comfortable gripping surface for easy connection and disconnection. The strain relief at both ends is moulded integrally with the jacket, providing a seamless transition that resists cracking and extends the cable’s fatigue life.

Electrical Performance and Noise Rejection

In production environments, electrical noise from motors, welding equipment, and variable‑frequency drives can interfere with control signals. The PF4 Tool Cable 5M ST employs a comprehensive shielding strategy: each signal pair is wrapped in a conductive foil, and the entire bundle is covered by a dense tinned copper braid. This provides >95% shielding effectiveness, ensuring that the controller receives clean encoder and torque data. The cable’s low capacitance and balanced impedance minimize signal distortion, allowing error‑free communication at bus speeds up to 1 Mbps.

System Compatibility

This cable is explicitly designed for use with Atlas Copco Power Focus 4 controllers and all PF4‑compatible electric nutrunners and screwdrivers. It is the recommended cable for tools such as the Tensor ST, Tensor SR, and ETV series when a straight connector is preferred. It is also backward‑compatible with Focus 4000 controllers when used with a suitable adapter (sold separately). The cable supports hot‑swapping, so tools can be changed on the fly without powering down the controller.

Applications

The 5M ST cable is widely adopted in:

• Automotive final assembly – for powertrain and chassis fastening

• Aerospace structural assembly – where data traceability is critical

• Wind energy manufacturing – bolting of tower and nacelle components

• Rail vehicle production – reliable connections for heavy‑duty tools

• General industrial maintenance – portable tool carts in service bays

Installation and Cable Management

For optimal performance, the cable should be routed using a cable carrier or guide tube to prevent it from becoming tangled or crushed. Avoid sharp bends close to the connectors, as this can cause premature fatigue. The straight connector allows the cable to pass through small openings and tight spaces, making it ideal for retrofitting existing workstations.

Maintenance and Service

Although the cable is designed for long life, periodic inspection is advised. Check for cuts, abrasions, or cracking of the jacket, especially where it rubs against machine parts. If damage is found, replace the cable with an original Atlas Copco part to maintain system integrity. The modular connector design makes replacement straightforward, with no need for soldering or special tools.

Environmental and Safety Compliance

This cable meets the requirements of UL 758, CSA C22.2, and EN 50525. The TPE jacket is halogen‑free and flame‑retardant (VW‑1 rating). It is also resistant to common industrial fluids such as motor oil, hydraulic fluid, and coolant, ensuring safe operation in wet or oily environments.

Conclusion

The Atlas Copco PF4 Tool Cable 5M ST (4220 2636 05) is a superior choice for connecting your Power Focus 4 tools. Its combination of flexibility, shielding, and durability ensures that your fastening processes remain accurate and reliable. Trust in this genuine Atlas Copco cable to deliver consistent performance and long service life, making it an indispensable component of your assembly system.
