We provide a precise SSI multiturn absolute encoder 1:1 replacement solution for the X 700.M121202 and X 700.M121402 models, developed for direct integration into existing industrial automation and motion control systems. This replacement matches the original encoders’ electrical interface, SSI communication timing, and mechanical footprint, allowing seamless installation without changes to PLC logic, cabling, or controller configuration.
These encoders deliver high-resolution absolute position feedback via a Synchronous Serial Interface (SSI), combining 14-bit singleturn accuracy with 12-bit multiturn tracking to provide a complete absolute position value over many revolutions. The SSI output supports both Gray and binary code formats, ensuring reliable and repeatable data communication even in dynamic motion environments. Fast initialization and robust signal integrity make this replacement suitable for real-time feedback in servo drives, robotics, CNC axes, and precision positioning systems.


Mechanically, the replacement units conform to standard industrial shaft and flange mounting conventions, enabling direct substitution without mechanical redesign. Their industrial-grade construction with IP67 protection ensures dependable performance under vibration, shock, dust, and moisture exposure. Integrated self-diagnostic functions continuously monitor code continuity and internal signal health, supporting predictive maintenance and reducing unplanned downtime.
This 1:1 replacement solution is ideal for automated machinery, motion control platforms, and positioning applications that demand accurate absolute feedback and long-term operational stability.
