Exactly as described

Arrived quickly and matched the specifications perfectly. The twist rate of the pairs is consistent, which is crucial for differential signaling. Will order again for our next project.

Reliable signal transmission

We installed 200 meters of the 4-core 1.5mm² version for a long-distance communication line. Signal integrity remained perfect throughout the run. No dropouts or interference.

Essential for clean data

If you are running Modbus or any serial communication in an area with motors or VFDs, do not skip the shielding. This cable solved our intermittent connection errors immediately.

Perfect for industrial automation

Used this cable for connecting our PLC sensors via RS485. The shielding is excellent and eliminated the noise issues we were having with unshielded wire. Highly recommended for factory environments.

Good quality, stiff jacket

The copper quality is top-notch and conductivity is great. The only minor downside is that the outer jacket is a bit stiff, making it slightly harder to route in tight corners, but durability seems worth it.

Great value for money

Compared to other branded shielded cables, this offers similar performance at a better price point. The braiding coverage looks dense and effective against EMI.

5 FAQ

Q: Is the copper tinned or bare?

A: The individual conductors are made of stranded oxygen-free copper, and the shielding braid is specifically tinned copper for enhanced corrosion resistance and solderability.

Q: What is the exact outer diameter of the 4-core 0.75mm² version?

A: The approximate outer diameter for the 4-core 0.75mm² configuration is 6.8mm. Please allow a tolerance of ±0.2mm depending on the production batch.

Q: Is this cable suitable for outdoor direct burial?

A: While the PVC jacket is durable, this specific model is designed for indoor or conduit use. For direct burial, we recommend adding an additional protective conduit or selecting our armored variant.

Q: Can I use this for 24V DC power delivery as well as signal?

A: Yes, the 1.5mm² variant can safely handle 24V DC power alongside signal transmission, provided the total current does not exceed the ampacity rating for that gauge.

Q: Does the shield need to be grounded at both ends?

A: For RS485 applications, it is generally best practice to ground the shield at one end only to prevent ground loops, unless specific site requirements dictate otherwise.
