For equipment originally configured with AG661 17 – 466117000000, a dedicated customized replacement encoder can be implemented to maintain the original control logic and mechanical layout. This replacement approach prioritizes compatibility at the interface, signal, and mounting levels, allowing the encoder to be integrated without changes to PLC programs or mechanical assemblies.
The replacement encoder adopts a multi-turn absolute measuring principle with an SSI Gray-code interface, ensuring consistent data structure and timing with the original configuration. Position information is resolved at 4096 steps per revolution combined with 4096 multi-turn counts, supporting precise positioning over extended travel ranges. The encoder operates on a DC 10–32 V supply and supports a maximum SSI clock frequency of 300 kHz, which is sufficient for responsive feedback in automated motion systems. Mechanically, the design supports continuous operation up to 8000 rpm and is reinforced to withstand 100 g shock and 20 g vibration, improving reliability in moving or impact-prone installations. The sealed IP67 housing allows stable performance in environments exposed to dust, oil mist, or moisture.


This AG661 17 – 466117000000 replacement solution is suitable for use in lifting equipment, automated logistics systems, shuttle cars, and other industrial applications where accurate absolute position feedback is required to ensure controlled and repeatable motion.
