Slim 4-Pin Extension Cable ProXtend M4S-03 — 3 m, black

ProXtend M4S-03 is a slim 4-pin extension cable in black with a 3 m length, designed to extend 4-pin connectors without modifying original wiring. Its slim profile and flexible jacket allow easier routing through tight spaces and behind panels, providing a discreet extension for PC fans, LED strips and other 4-pin peripheral connections. The cable maintains the original connector orientation and pinout for plug-and-play compatibility.

Advantages

The slim construction reduces bulk and improves airflow management inside enclosures while offering a full-length extension for devices that require a 4-pin connection. The flexible insulation and narrow cross-section simplify cable management and mounting in constrained areas. Standard 4-pin connectors preserve signal integrity and ensure compatibility with existing headers and peripherals.

Suitable for

• Extending PC fan connections where extra length is needed
• Connecting or extending 4-pin LED strips and lighting controllers
• Routing 4-pin peripheral cables in compact desktop or server builds
• Temporary repairs or replacements of short internal 4-pin leads

Key specifications

• Cable type: 4-conductor extension cable with 4-pin connectors
• Length: 3 meters
• Colour: black
• Profile: slim, low-profile jacket for tight routing
• Weight: 0.01 kg

How to use

Align the 4-pin connectors and insert the male plug into the female header of the device or motherboard, then connect the opposite end to the peripheral. Ensure the connector keying and pin orientation match the original wiring before powering the system. Route the cable along secure paths using cable ties or clips as needed, keeping it clear of moving parts and hot surfaces.

Recommendations

Use this slim extension for low-voltage internal connections only; avoid exposing the cable to excessive heat, moisture or mechanical strain. Regularly inspect connectors for secure fit and signs of wear. For high-current applications, verify the cable gauge and connector ratings are sufficient.
