LiYY Flexible PVC Control and Signal Cable – Multi-Core, DIN Colour Code | HANYI Cable
Detailed Description
The LiYY cable is a high-quality, flexible, unscreened data and control cable designed for low-frequency applications. Constructed with fine-stranded copper conductors and PVC insulation, each core is color-coded according to DIN 47100 for easy identification. The outer sheath is made from durable PVC, offering excellent flexibility, compact diameter, and smooth handling in tight installation spaces.
LiYY cables are widely used in electronics, signal and data transmission, control panels, measuring devices, office machines, medical equipment, and industrial automation systems. Thanks to their small bending radius and light weight, they are ideal for applications where space is limited and mobility is required.
