Tired of signal noise and broken cables in your factory?
You know the struggle. You install a new control system, and everything works fine for a week. Then, the motors start, the machines heat up, and suddenly your data screen goes crazy. Sensors give wrong readings. The system stops for no reason. You check the wires, and the insulation is cracked, or the shield is loose. This costs you money in downtime and repairs. You need a cable that doesn’t just carry power and data but protects them from the harsh reality of industrial life. You need a wire that resists oil, resists bending, and kills electromagnetic noise before it ruins your signals.This is not just a wire. It is a shield for your business. We are talking about the German-engineered ÖLFLEX CLASSIC 115 CY. Specifically, the 12-core 0.5 sq mm version. It is built for the tough jobs. It handles power and delicate data signals in the same jacket without them fighting each other. If you are running servo motors, CNC machines, or wind turbine loops, this is the cable you need.
What makes this 12-core shielded cable special?
Let’s look under the hood. This cable is designed to be thin, light, and tough. It uses a special construction that skips the heavy inner sheath found in older cables. This makes it smaller and easier to pull through tight conduit pipes. But don’t let the size fool you. It is packed with features.The core of the cable is made of fine-stranded copper. We are talking about Class 5 flexibility per VDE 0295. This means the copper is not one solid stick. It is made of many tiny wires twisted together. This allows the cable to bend and twist thousands of times without snapping. It is perfect for drag chains or moving parts.The “brain” of the cable is the shielding. It uses a double-shield system. First, there is an aluminum foil around the twisted pairs. This blocks high-frequency noise. Then, there is a tinned copper braid covering the whole cable. This braid catches low-frequency interference. Together, they create a Faraday cage. Your data stays clean. Your power stays stable.The outer jacket is PVC. But it is not cheap plastic. It is formulated to resist oil, acids, and scratches. It can handle temperatures from -30°C to +70°C. If you are in a cold storage warehouse or a hot steel mill, this jacket won’t crack.

This cable meets the German VDE standards. That means it has been tested for safety and durability. You aren’t buying a “maybe” product. You are buying a certified industrial component.
Where should you use this cable?
This 12-core 0.5 sq mm shielded cable is a multi-tool for industrial automation. You can use it for almost anything that needs power and a signal in one line.##### Industrial Networking & Data TransmissionIf you are setting up a Profibus or Ethernet network in a noisy factory, this cable is your best friend. The double shield stops the electromagnetic interference (EMI) from heavy welders or large motors. Your data packets arrive intact. No retries. No errors.##### Control Systems & PLC CabinetsInside a control cabinet, space is expensive. The ÖLFLEX 115 CY is slim. You can fit more wires in the same duct. It is perfect for connecting PLCs to sensors, switches, and relay modules. The black sheath with white number printing makes it easy to identify which wire goes where.##### Servo Motors & EncodersServo motors move fast and bend the cables attached to them. Standard cables break at the connector point. This cable has high tensile strength and anti-stretch properties. It is designed for torsion applications, like the loops in wind turbine generators. It twists and turns without breaking the internal copper.##### Power & Signal Hybrid UseYou can use the 0.5 sq mm cores for 24V DC control power and the same cable for data. This saves you money on installation. You only need to pull one cable instead of two. Just make sure your current draw matches the wire gauge (max 2.5A per core in open air).
Why choose German Quality over generic imports?
You see a lot of cheap cables online. They look the same. They have 12 cores and a gray jacket. But when you cut them open, the difference is huge.Cheap cables often use recycled copper or copper-clad aluminum. This increases resistance. Over 100 meters, you lose voltage. Your motor might not start, or your sensor gives a false “low battery” alarm. The shielding on cheap cables is often just a thin foil that tears when you strip the jacket.The ÖLFLEX CLASSIC 115 CY uses high-purity oxygen-free copper. The resistance is low. The shielding coverage is high (over 85% braid coverage). The PVC jacket doesn’t smell like toxic chemicals when you strip it. It is built to last 10 years, not 10 months.We test every batch. We check the conductor resistance. We check the insulation resistance. We check that the shield is continuous. You get a test report before we ship. You pay for quality, not for marketing hype.
Installation Tips for Best Performance
To get the most out of this cable, follow these simple rules:
- Respect the Bending Radius: Don’t kink the cable. The minimum bend radius is about 6 times the diameter (approx 50mm). If you bend it too sharp, you damage the shield and the insulation.
- Ground the Shield Correctly: The shield works best if you ground it at one end (usually the control panel end). If you ground both ends, you can create a ground loop. This actually causes noise instead of stopping it.
- Use the Right Glands: When entering a box or machine, use EMC cable glands. These metal glands clamp onto the braid and connect it to the metal chassis. This completes the shield.
- Separation: Even though this cable is shielded, try to keep it away from high-voltage power cables (400V+). Run them in separate trays if possible.
Frequently Asked Questions
Is this cable flame retardant?Standard PVC cables are self-extinguishing (IEC 60332-1), but they are not halogen-free. If you need a halogen-free version for tunnels or buildings, ask us about the LSOH (Low Smoke Zero Halogen) options.Can I bury this cable underground?Yes, but you must use a conduit pipe. The PVC jacket is tough and resists moisture, but direct burial without protection is not recommended for control cables.What is the difference between 0.5 sq mm and 0.75 sq mm?The 0.5 sq mm is rated for about 2.5 Amps continuous. The 0.75 sq mm is rated for about 4-5 Amps. If your device draws more than 2.5A, go for the 0.75 sq mm version to avoid overheating.Can you ship to the USA/EU with customs cleared?Yes. We do DDP (Delivered Duty Paid) shipping. We handle the customs paperwork and taxes. The cable arrives at your door. You don’t have to deal with the broker.
