We provide a precision SSI absolute encoder 1:1 replacement solution for the X 700.A101202 and X 700.A121202 models, engineered to match the original devices in electrical interface, signal timing, and mechanical fit. This replacement integrates directly into existing control systems without changes to wiring layouts or controller configuration, ensuring seamless substitution in automation and motion control applications.
This encoder delivers high-resolution absolute position feedback via a Synchronous Serial Interface (SSI), typically supporting resolutions up to 14 bits per revolution. Stable and repeatable Gray or binary code output provides accurate position data immediately after power-on, eliminating the need for homing or referencing. The SSI interface supports high data rates with robust signal integrity, making it suitable for real-time feedback in servo drives, CNC equipment, and robotics.
Mechanically, the replacement encoder is designed to fit standard industrial mounting arrangements, facilitating straightforward installation on existing shafts and flanges. A rugged enclosure with IP67 protection and robust construction ensure reliable performance in harsh industrial environments exposed to vibration, shock, dust, and moisture. Low power consumption and fast initialization further contribute to system responsiveness.


This 1:1 replacement solution is ideal for industrial automation systems that require dependable absolute feedback and long-term operational stability.
