IFM absolute singleturn encoders provide a unique digital position value for every angular position within one complete revolution. They maintain the shaft position information even after power loss, eliminating the need for a homing cycle after restart. The range uses magnetic sensing technology and provides up to 13-bit resolution, equivalent to 8,192 position steps per revolution. Available interfaces include CAN and Profibus, depending on the model. These encoders are well suited for precise rotary positioning, angle measurement, and industrial motion-control applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
Absolute singleturn encoders continuously determine the exact angular position of a rotating shaft within 0° to 360°. Unlike incremental encoders, they provide an absolute position value rather than requiring pulse counting from a reference point. The 13-bit resolution provides 8,192 distinct position values per revolution. This enables accurate positioning of rotary mechanisms and machine axes. The technology is particularly useful where reliable position information is required immediately after power restoration.
A key advantage of absolute singleturn technology is position traceability without a homing operation. The encoder stores or provides the absolute shaft position independently of incremental pulse counting. This reduces machine restart time after power interruptions. It is especially useful for rotary indexing tables, steering mechanisms, actuators, and positioning systems. The result is improved machine availability and simplified control-system operation.
IFM absolute singleturn encoders are available with industrial communication interfaces such as Profibus and CAN/CANopen, depending on the product version. These interfaces allow position information to be transferred directly to automation controllers. Configurable resolution and signal characteristics provide flexibility during machine commissioning. Fieldbus communication also supports integration into distributed industrial control architectures. This makes the encoders suitable for both conventional and advanced automation systems.
The absolute singleturn range uses industrial encoder housings with solid-shaft configurations. IFM offers versions with 6 mm and 10 mm solid shafts, allowing selection according to the mechanical installation. The encoder family uses magnetic sensing, which requires fewer components than optical systems and supports a compact, robust construction. Depending on the model, aluminium housings, stainless-steel shafts, and industrial protection ratings are available. These characteristics support reliable operation in demanding automation environments.

Absolute singleturn encoders are suitable for applications where the controller needs the exact shaft angle rather than only rotational pulses. The absolute value can be used for closed-loop positioning and machine sequence control. High-resolution feedback helps improve repeatability in rotary mechanisms. Fieldbus versions can transmit position data directly to the machine controller. This simplifies integration where accurate angular feedback is essential.
Magnetic encoder technology provides a compact sensing solution with fewer mechanical components than traditional optical encoder designs. IFM's encoder portfolio includes robust industrial housing configurations and shaft options for different machine installations. The available communication interfaces allow the encoder to be matched to the automation architecture. Absolute position feedback also reduces the operational impact of unexpected power interruptions. These features make the range suitable for continuous industrial positioning applications.
