Cable Pulls and Cable-Pull Rotary Encoders: Wide Range of Applications in Linear Distance Measurement

At a Glance:

• Pepperl+Fuchs has relaunched its cable pull portfolio.
• Four product lines and comprehensive accessories offer individual solutions for a variety of applications.
• The length-proportionate drum rotation is recorded by magnetic rotary encoders, which combine robustness and accuracy with the latest magnetic field technology.
• A convincing case study is the AGV (automated guided vehicle), in which Target Line cable pulls combine with ENA58IL magnetic absolute rotary encoders with proven optimum effect.
• The new Premium Line cable pulls combined with the newly developed magnetic rotary encoders (both from Pepperl+Fuchs) offer perfect solutions that contribute to a more efficient, smoother and more reliable material flow.

Pepperl+Fuchs: The cable-pull rotary encoder portfolio from Pepperl+Fuchs is characterized by modular product architecture. The range offers a wide variety of variants for almost every field of application. Optimally coordinated components signify a long service life and ensure reliable processes with regard to linear distance measuring and positioning.

Direct Measurement of Linear Movements

Cable-pull rotary encoders are ideal for recording linear movements. Inside a cable pull, a steel cable winds around a spring-loaded drum. This drum rotates the drive shaft of a rotary encoder when the cable is extended or retracted, thereby converting a translational movement into a rotary movement.

Modular Design for Any Application

The consistent, modular design enables optimal calibration of cable pull, rotary encoder, and accessories. Ranging from an incredibly compact design to an extremely robust variant, the portfolio covers a wide range of applications. The variants enable distances of up to 60 m to be recorded. Standardized interfaces facilitate integration into any system environment. A comprehensive range of accessories allows the cable pulls to be used even under the harshest conditions.

Robust Enough for Offshore Applications

Cable-pull rotary encoders have proven to be a practical solution across many industrial sectors. Automated guided vehicles represent one typical application. In such instances, the rotary encoders are integrated into a lifting unit for the purpose of recording position and speed. The same applies for applications such as in mobile extending cranes. In this case, the rotary encoders monitor linear retracting or extending movements of booms in real time, sending precise information about the boom's current position to the electronic crane control unit. Specially designed for outdoor use, Pepperl+Fuchs offers heavy-duty variants that have proven successful in shipbuilding and offshore applications. These variants reliably monitor motion processes of mobile machinery, conveyor systems, cranes, and wind power plants in extreme weather conditions.
