High-Flex Shielded Encoder Cable (TRVVPS)

High-Flex Shielded Encoder Cable (TRVVPS)

Precision Signal Transmission for Dynamic Automation

In the world of industrial automation, a dropped signal isn’t just a glitch—it’s downtime. The TRVVPS High-Flex Shielded Encoder Cable is engineered to solve the two most critical challenges in motion control: maintaining signal integrity amidst electrical noise and surviving millions of bending cycles in drag chains.

Manufactured by Shanghai Rousheng Wire And Cable Co., Ltd., this cable series is designed for the rigorous demands of servo systems, CNC machinery, and robotic arms. whether you are powering a production line in Germany or upgrading equipment in Brazil, this cable delivers the reliability your operations demand.

Engineered for Continuous Motion

Standard cables fail under the stress of constant movement. They kink, the insulation cracks, and eventually, the copper conductors break. The TRVVPS series is different. It is built specifically for drag chain applications where high flexibility and small bending radii are non-negotiable.

Superior Electromagnetic Compatibility (EMC)

Encoder signals are sensitive. In an industrial environment packed with VFDs and high-voltage motors, electromagnetic interference (EMI) can cause positioning errors.

• Twisted Pair Construction: We twist the conductors in precise pairs to cancel out electromagnetic interference naturally.
• High-Coverage Shielding: An optional tinned copper braid or composite shield acts as a fortress around your data, grounding out noise and ensuring your encoder feedback remains accurate.

Durable PVC Jacket

The transparent PVC sheath isn’t just for aesthetics; it allows for visual inspection of the shield integrity while providing robust protection.

• Oil Resistance: Withstands exposure to industrial coolants and lubricants.
• Abrasion Resistance: Tough enough to glide inside cable carriers without wearing down.
• Flexibility: Formulated to remain flexible, preventing the jacket from cracking during repetitive bending.

Frequently Asked Questions (FAQ)

What is the difference between TRVVP and TRVVPS cables?

While both are shielded flexible cables, the S in TRVVPS typically denotes Twisted Pairs (Twisted Pair Shielding). Twisted pairs are crucial for data and signal transmission (like in encoders) because they are far more effective at cancelling out crosstalk and electromagnetic interference than standard parallel conductors found in TRVVP.

Can this cable be used in outdoor environments?

Standard PVC cables are designed primarily for indoor use. If your application involves direct exposure to UV radiation or extreme weather, please contact our engineering team. We can customize the jacket material (e.g., using PUR or special UV-resistant PVC) to ensure longevity outdoors.

How do I choose the right cross-section for my encoder?

For signal transmission over short to medium distances, 0.2mm² or 0.3mm² is often sufficient. For longer runs where voltage drop might be a concern, or for combined power/signal cables, consider stepping up to 0.5mm² or 0.75mm². Always consult your encoder manufacturer’s manual for their specific recommendation.

What is the minimum bending radius for this cable?

To ensure a long service life in a drag chain, we recommend a minimum bending radius of 7.5 times the outer diameter (OD) of the cable. Bending the cable tighter than this limit adds mechanical stress to the copper strands and shield, leading to premature failure.
