This PDK71902 flexible control cable is specifically designed for industrial automation, instrumentation, and low‑power signal transmission applications requiring a durable, oil‑resistant cable with a small overall diameter. It features four 0.25 mm² (approx. AWG 23 equivalent) stranded bare copper conductors – an ideal size for low‑voltage control signals, sensor wiring, PLC I/O, and data communication in compact equipment. All conductors are bare copper to ensure low resistance and stable signal integrity. PE (Polyethylene) provides primary insulation with excellent dielectric properties, very low moisture absorption, and consistent impedance – critical for reliable analog and digital signal transmission in humid environments. The outer jacket is extruded from TPU (Thermoplastic Polyurethane) , delivering outstanding abrasion, oil, and hydrolysis resistance, along with flexibility even at low temperatures. The cable is suitable for fixed installation or occasional flexing in machine tools, robotic arms, conveyor systems, and automated production lines. By combining fine‑gauge bare copper conductors, PE insulation, and a rugged TPU sheath, this cable offers a reliable, long‑lasting solution for low‑current control and signal circuits in harsh industrial environments.

Key Features – Bare Copper Conductors, PE Insulation, TPU Sheath
Bare copper conductors (4×0.25 mm²) – four stranded bare copper cores for low‑current control signals (e.g., 4‑20 mA, 24 VDC discrete I/O, thermocouple extension); bare copper ensures high conductivity and minimal signal attenuation.
PE insulation – rated -40°C to +105°C; low dielectric constant, negligible moisture absorption, and resistance to seawater, acids, and alkalis – providing stable insulation resistance and capacitance.
TPU outer sheath – polyurethane jacket offers superior abrasion, tear, and cut resistance; remains flexible in cold conditions and resists oils, greases, UV, and hydrolysis – ideal for machine tool environments with coolant and lubricant exposure.
Color‑coded cores – individual conductor colors (e.g., brown, blue, black, green/yellow) for easy identification and wiring in control cabinets.
Compact and lightweight – the small cross‑section allows space‑saving installation in crowded junction boxes, cable ducts, and robotic wrists.
Ideal For
Sensor and actuator wiring in automated manufacturing lines (proximity switches, photoelectric sensors)
PLC analog and digital signal connections in control panels
Robotic arm internal wiring for end‑effectors and feedback devices
Machine tool coolant‑resistant wiring (lathes, milling machines, grinders)
Building automation and HVAC control circuits
Any industrial application demanding a 4‑core 0.25 mm² control cable with exceptional flexibility and oil resistance
Conclusion
This PDK71902‑4*0.25 TPU cable provides a compact, flexible, and durable solution for low‑level signal transmission in harsh industrial settings. The combination of bare copper conductors, PE insulation, and a tough TPU sheath ensures stable performance, long service life, and resistance to oils, moisture, and mechanical wear. It is an ideal choice for automation, control panels, and sensor networks.
