Signal Interference and Cable Failure — The Hidden Cost in Automation
In factory automation, CNC machining, and process control, signal integrity is everything. EMI from servo drives, VFDs, and welding equipment corrupts low-voltage control signals — causing machine faults, data loss, and unplanned downtime. Single-shield cables crack under repeated flexing. Unshielded wire picks up noise in dense cable trays. You need a cable that blocks interference AND survives real mechanical stress.
Imported 50-Core 0.15mm² Double-Shielded Twisted Pair Signal Cable
This 50-core shielded signal control cable is built for demanding industrial environments. Each of the 25 twisted pairs uses 26 AWG (0.15 sq mm) tinned copper strands, individually wrapped in foil and covered by an overall tinned copper braid shield — dual shielding for maximum EMI/RFI suppression. The flexible PVC jacket handles tight bends in control panels, drag chains, and robotic joints without signal degradation. Imported raw materials ensure consistent conductor resistance and shield coverage across every meter.

Why This Cable Performs Where Others Fail
Dual-layer shielding blocks noise where it matters most. The foil shield handles high-frequency RFI (10kHz–10GHz), while the tinned copper braid absorbs low-frequency EMI from motors and transformers. Tested in environments with VFDs and welding stations — signal attenuation stays below 3dB over 100m runs.Tinned copper resists corrosion in harsh conditions. Unlike bare copper, the tin plating prevents oxidation in humid plants, chemical processing areas, and outdoor enclosures. Contact resistance stays stable for years — no intermittent faults from green corrosion buildup.Engineered for continuous flexing in moving machinery. At 6×OD bend radius, this 26 AWG flexible wire survives drag chain routing on CNC machines, robotic arm joints, and automated guided vehicles. Field-proven beyond 10 million flex cycles without conductor breakage.Consistent pair-to-pair isolation reduces crosstalk. Tight twist pitch on each pair, combined with individual foil wrapping, keeps near-end crosstalk (NEXT) below -40dB — critical when 50 signals run side by side in a single jacket.
