The control cable YSLY-JZ 25X1,0 from Xaver Bechtold is a flexible control cable for use in industrial plants. It is used for connecting control devices on machine tools, conveyor and assembly lines, material handling systems, as well as in general plant engineering. The cable is suitable for fixed installation and flexible applications, particularly for free movement without tensile stress and without forced movement guidance under moderate mechanical loads. It can be operated in dry, damp, and wet rooms.

Applications

The cable is designed for use in industrial environments where reliable signal transmission between control devices and drives is required. It is particularly suitable for installations where the cable is moved, but without direct tensile load. The operating conditions include both stationary installations and moving applications, with moderate mechanical loads. The cable is suitable for indoor use, regardless of humidity, as long as no aggressive chemicals or extreme temperatures are present.

Functions and Equipment in Detail

The control cable consists of copper conductors, which are bare, fine-stranded, and manufactured according to VDE 0295 Class 5. The conductors are insulated with PVC and marked according to VDE 0293-308. The marking is done with black conductors featuring a continuous digit print, while the protective conductor is green-yellow. The conductors are stranded in layers, ensuring even distribution of mechanical stress. The sheath is made of PVC and is gray in color. The designation, dimensions, and VDE registration number are printed on the sheath.

Technology Explained Simply

The rated voltage is 300/500 V, which is sufficient for most industrial control applications. The test voltage of 4000 V ensures the electrical strength of the insulation. The temperature ranges are defined as -5 °C to +70 °C for moving applications and -40 °C to +80 °C for fixed installations. The bending radius is 4 times the cable diameter for fixed installation and 15 times for flexible applications. Flame retardancy corresponds to VDE 0472 Part 804, Test Method B (equivalent to IEC 332-1), indicating limited flammability under direct flame exposure. The cable is largely resistant to acids, alkalis, and certain hydrocarbon compounds, making it suitable for use in chemically demanding environments.

Compatibility and Accessories

The control cable is designed for use with standard connectors and terminals suitable for PVC insulation. The conductor marking according to VDE 0293-308 enables clear identification and simplifies installation. The cable is compatible with other YSLY control cables and can be used as a replacement or addition in existing installations.

Installation and Mounting

Installation is carried out by fixed mounting or flexible application, ensuring the bending radii are maintained. For moving applications, a bending radius of 15 times the cable diameter must be observed; for fixed installation, 4 times is sufficient. The cable must not be installed under tensile stress. Connections to control devices are made using appropriate connectors or terminals. Installation is possible in dry, damp, or wet rooms, provided the temperature limits are not exceeded.

Operational Advantages

The control cable offers high mechanical stability in flexible applications, thanks to the fine-stranded copper conductors and stranded cores. The PVC insulation and gray sheath ensure good chemical resistance and flame retardancy. The clear marking of conductors simplifies installation and maintenance. The cable is suitable for use in industrial environments with moderate mechanical loads and variable environmental conditions.

Protection Rating

The cable is not designed as an IP-rated product, but as a PVC control cable with defined operating conditions. The specifications for temperature resistance and flame retardancy refer to the materials and not to an IP protection rating. Use in wet rooms is possible, but without a specific protection rating such as IP67.

PoE

The cable is not designed for power over Ethernet (PoE). The rated voltage of 300/500 V is intended for control and signal transmission, not for powering PoE devices.

Cable Type

The cable type YSLY-JZ corresponds to a flexible control cable with numbered conductors and an integrated protective conductor. The designation YSLY stands for a PVC control cable with bare copper conductors manufactured as fine-stranded. The marking JZ refers to black conductors with continuous digit printing and a green-yellow protective conductor.

VDE Standard

The cable complies with VDE standards VDE 0295 Class 5 for the conductors, VDE 0293-308 for conductor marking, and VDE 0472 Part 804, Test Method B for flame retardancy. The VDE registration number is printed on the sheath, enabling approval and identification of the cable.
