High resolutions can be easily achieved with Pepperl+Fuchs optical rotary encoders. A code disk with radial slits is used for this purpose. An LED sends light through the radial slits to a receiver located on the other side of the code disc. The rotation of the disk modulates the light, and the receiver converts it into an electrical signal.
The magnetic rotary encoders from Pepperl+Fuchs are particularly robust and therefore ideally suited for use in harsh environments. Due to energy harvesting, the magnetic absolute rotary encoders do not require an external power supply to save their current position. As a result, they perform reliably even in the event of power failures.
In addition to rotary encoders with integral bearing, Pepperl+Fuchs also offers a selection of bearing-free rotary encoders. These sensors enable particularly space-saving installation due to their low mounting depth. Thanks to noncontact and wear-free scanning, they also ensure reliable operation even in harsh environmental conditions.
Absolute rotary encoders are used wherever precise control of motion sequences is required. Pepperl+Fuchs offers a comprehensive portfolio of absolute rotary encoders that provide information for complex control tasks.
Incremental rotary encoders from Pepperl+Fuchs have a very high resolution of up to 50,000 pulses per revolution. By detecting rotation angles and speeds, they enable precise control of rotary movements.
Cable-pull rotary encoders are used for linear position measurement. The modular portfolio from Pepperl+Fuchs offers a wide range of variants—for reliable processes in almost any application.
Only perfectly matched connection and mounting technology ensures optimal integration of rotary encoders. Pepperl+Fuchs offers the right accessories for every installation environment.
