Oscar Lapp
Oscar Lapp the inventor of the world’s 1st industrial, flexible and oil resistant control cable with color coding.
ÖLFLEX – Oil resistant Flexible cable
Before this innovation, installers had the tedious and time consuming task of wire testing all gray or all black cores. Color coding the cores not only made the process easier, but also greatly improved safety with more accurate testing.
ÖLFLEX
The success of LAPP’s ÖLFLEX® lies in its commitment to engineering high-quality flexible power and control cables. Designed to meet diverse applications, installation conditions, and mechanical requirements, ÖLFLEX® cables deliver consistent performance across a wide range of industrial environments based on three core principles.
Flexibility for dynamic applications
Durability in the toughest of industrial environments
Compliance with international safety and high performance standards
Designs and Core Configurations
Numbered cores
for straightforward wiring and easy identification
Color-coded cores
commonly used in control and automation systems
Cores with green-yellow protective conductor (PE)
for grounding and safety
Paired or twisted cores
for signal stability and reduced interference

Shielded and Unshielded Variants
To ensure signal integrity in electrically noisy environments, ÖLFLEX® cables are available in:
Unshielded versions
Shielded versions (braided copper shield)
Shielded ÖLFLEX® cables are widely used in Automation systems, Frequency converters, Industrial communication and signal transmission.
Special Properties and Identification
On the LAPP online catalogue, each ÖLFLEX® product page shows a row of grey icons representing the features specific to that cable.
These appear under the product picture and summary on the page. You can visit LAPP’s catalog and search for any product to see those icons.
These are fast and convenient signals to find the appropriate product, respectively, to the operational and environmental conditions required.
