This product is a high-performance custom flexible cable specifically designed for compact signal transmission, sensor connections, control circuits, medical devices, robotics, and harsh environment applications where small size, electrical reliability, and extreme durability are required. The PDK71902 features four 0.3 mm² tinned copper stranded conductors with polyethylene (PE) insulation, all enclosed in a high-grade thermoplastic polyurethane (TPU) outer sheath. This construction delivers stable low‑capacitance signal transmission, excellent flexibility, superior moisture resistance, and outstanding protection against abrasion, chemicals, UV, and mechanical stress.

Temperature range
Unlike standard PVC‑insulated or ordinary polyurethane cables that may suffer from higher signal attenuation, moisture absorption, or limited temperature range, the PDK71902 is engineered for precision and longevity. The tinned copper conductors resist oxidation and corrosion, ensuring low and stable contact resistance even in humid or saline environments. The PE insulation provides a low dielectric constant and low dissipation factor, making it ideal for high‑frequency or sensitive analog signals (e.g., 4‑20 mA loops, encoder feedback, low‑voltage sensors). The TPU sheath offers exceptional tear strength, notch resistance, hydrolysis resistance, and flexibility from ‑40 °C to +80 °C. Unlike rubber or PVC jackets, TPU does not plasticize or harden over time, and it resists oils, greases, solvents, and UV exposure. This design eliminates signal drift due to insulation degradation and ensures reliable operation in mobile or fixed installations.
Ideal for:
Miniature sensors, proximity switches, and photoelectric sensors in automated machinery
Medical devices (patient monitors, ultrasound probes, dental equipment) requiring small, flexible, and sterilizable cables
Robotics and pick‑and‑place arms where tight bend radii and continuous flexing occur
Encoder and resolver feedback lines for servo motors and motion control systems
Industrial fieldbus and I/O connections (DeviceNet, CAN bus, RS‑485) requiring low capacitance
Marine electronics, subsea instrumentation, and offshore control systems (TPU resists seawater)
Portable test equipment, data loggers, and battery‑powered handheld devices
Outdoor security cameras, solar panel sensors, and LED lighting control cables (UV resistant)
This cable simultaneously meets the demanding requirements of precision signal circuits for low attenuation, impedance matching, and noise immunity, while the TPU sheath eliminates the need for conduit or frequent replacement in abrasive or chemically aggressive environments. The tinned copper conductors ensure easy soldering and termination. The four cores are color‑coded or numbered (customizable) for straightforward field identification. The compact 4×0.3 design saves space in cable carriers and tight equipment enclosures. The combination of PE insulation and TPU jacket provides excellent electrical stability (stable capacitance vs. temperature) and mechanical protection against cutting, dragging, and flexing. All these features make the PDK71902 a reliable, long‑life, and cost‑effective solution for demanding signal and low‑power applications.
