Double-Shielded Twisted Pair PVC Signal Cable 300 V

This twisted-pair signal and control cable combines semi-rigid PVC insulation with aluminum foil and tinned copper braid double shielding. It is designed for reliable transmission of sensitive paired signals in industrial environments with high electromagnetic interference.

Key Highlights

Twisted-pair construction · Aluminum foil and copper braid double screen · Tinned copper conductors · Reduced crosstalk · Excellent EMC protection · 300 V UL/CSA reference design · PFAS-free · RoHS compliant

Application
Construction
Technical Data

Packaging

Designed for paired measurement, monitoring, control and communication signals requiring enhanced EMC protection.

Typical applications include:

Industrial weighing equipment
Low-voltage switchboards
Control and measurement systems
Interference-sensitive process controls
Electronic monitoring equipment
Sensitive industrial data systems

Common Questions

BEFORE YOU ORDER

For stocked configurations listed in the ordering table, MOQ is 100 metres per specification. Custom configurations — non-standard core counts, jacket colours, or special compounds — carry a 500 metre MOQ. Samples of 5–10 metres are available free of charge for qualification testing.

Use shielded (P or PP suffix) whenever the cable runs alongside servo drives, VFDs, or inverters, or when carrying encoder, sensor, or analogue signals. Unshielded is suitable for pure power distribution and simple on/off control lines. If in doubt, our engineering team can review your cabinet layout and advise — this is included with any quotation.

Yes. Send us the existing part number or a sample and we will produce a cross-reference specification with matching electrical, mechanical, and dimensional characteristics. Most cross-references are turned around within 3 working days, with a physical sample following within 7 days.

Standard shipments include the CE Declaration of Conformity, RoHS and REACH statements, and the batch test report. UL Recognition (UL 2464 / UL 20549) is available on request for North American projects — specify this at the quotation stage as it affects the material specification.

Standard configurations ship in 15 working days from order confirmation. Custom-engineered specifications typically require 20–25 working days, depending on compound availability. Rapid sampling for new specifications is 7 days. We will confirm the exact date in writing with your order acknowledgement.
