In many motion-control systems, the absolute encoder functions as the primary position reference rather than a simple feedback device. For applications specified with AG661 25 – 466125000000, a customized replacement encoder can be provided to retain this reference role while fitting directly into the existing mechanical and electrical configuration.
The replacement unit is built as a multi-turn absolute encoder using an SSI interface with Gray-code transmission, ensuring compatibility with established controller settings. It provides 4096 counts per revolution combined with 4096 multi-turn revolutions, allowing accurate absolute position tracking across long operating cycles and repeated start–stop conditions. The encoder operates within a DC 10–32 V supply range and supports SSI clock frequencies up to 300 kHz, delivering stable and deterministic position data. From a mechanical perspective, the design supports shaft speeds up to 8000 rpm and incorporates reinforced internal structures to withstand 100 g shock and 20 g vibration. An IP67-rated enclosure protects the sensing elements against dust, oil mist, and temporary water exposure.


Accordingly, the AG661 25 – 466125000000 replacement encoder is well suited for automated logistics systems, lifting mechanisms, transfer platforms, and other industrial equipment where reliable absolute position feedback is essential for safe and repeatable operation.
