Signal degradation and EMI interference remain top concerns in audio and control wiring — especially in tight panels and high-density rack installations. Cheap multi-pair cable adds noise, kinks during routing, and fails under repeated flex. Belden 3107A 2PR22 was engineered to solve exactly that: clean signal transfer in a compact, easy-to-route 2-pair format.The Belden 3107A is a 2-pair (2PR22) shielded signal/audio cable with 0.3mm solid conductors. Each pack contains two cables, pre-cut and ready for panel build-outs, studio patching, or machine-to-controller runs. Belden’s proven construction ensures consistent impedance and low capacitance across the pair — critical for balanced audio and low-level sensor signals.Core Specifications

Why Choose Belden 3107A for Demanding Installations
- Shielded pair design blocks EMI/RFI. The foil-plus-drain-wire shield maintains signal integrity near VFDs, servo drives, and switching power supplies — common noise sources on factory floors and in broadcast racks.
- 0.3mm solid conductors balance flexibility and durability. Thin enough to bend cleanly in 20mm-wide wire ducts and DIN-rail channels, yet stiff enough to hold shape in punch-down blocks and terminal strips without fraying.
- 2-pack format cuts panel build time in half. Two pre-cut lengths per pack mean no on-site measuring or splitting. Installers pull, terminate, and move to the next point — reduces labor cost on repeat jobs.
- PVC jacket resists oil, abrasion, and UV exposure. Suitable for both indoor control cabinets and semi-outdoor industrial enclosures where cable contacts machine housings or conduit edges regularly.
Applicable Industries & Use Cases
- Industrial automation — sensor and I/O wiring in control cabinets, PLC racks
- Professional audio & broadcast — studio patching, intercom systems, loudspeaker feeds
- Security & access control — camera signal runs, door controller wiring
- Building automation — BACnet/Modbus low-voltage signal backbone in panels
- Machine building — internal signal routing inside CNC enclosures and robotic cells
