FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why does standard LiYCY PVC data cable fail rapidly inside CNC drag chains, whereas S 368 C survives millions of cycles?
Standard LiYCY uses Class 5 stranding, long lay pitches, PVC insulation (which stiffens in coolants), and a tight braid angle; S 368 C upgrades to superfine Class 6 copper, ultra-short concentric core pitches, low-capacitance TPE/PP insulation, a sliding fleece separator, and an oil-proof polyether PUR sheath.
When should I choose S 368 C (multicore) vs S 369 C TP (twisted pair)?
Choose S 368 C for single-ended 24 V digital I/O, proximity switches, and common-return sensors; choose S 369 C TP whenever signals are differential—such as RS-422/RS-485, incremental A/B/Z encoder channels, SSI, or load-cell bridges—where twisted pairs cancel magnetic crosstalk. Each production reel undergoes sweep-frequency impedance and return-loss verification, dielectric spark testing, and dimensional inspection before dispatch with an EN 10204 3.1 test certificate.
Why is low-capacitance TPE/PP core insulation used instead of PVC inside S 368 C?
Polyolefin/TPE has half the dielectric constant of PVC, cutting core-to-core capacitance to ~70 pF/m (vs ~130 pF/m for PVC) so high-frequency encoder pulses travel over longer drag-chain runs without pulse rounding. Each production reel undergoes sweep-frequency impedance and return-loss verification, dielectric spark testing, and dimensional inspection before dispatch with an EN 10204 3.1 test certificate.
Is S 368 C suitable for automotive paint shops and cleanrooms?
Yes, S 368 C is manufactured completely free of silicone and paint-wetting impairment substances (LABS-free / PWIS-free) and uses a low-abrasion matte PUR jacket. Each production reel undergoes sweep-frequency impedance and return-loss verification, dielectric spark testing, and dimensional inspection before dispatch with an EN 10204 3.1 test certificate.
