For the GM401.0202102 and GM401.A202102 variants, we offer a dedicated SSI encoder 1:1 replacement developed for demanding industrial environments. The replacement maintains identical functional behavior and interface characteristics, ensuring seamless integration during maintenance, retrofit, or lifecycle replacement projects.
Using an SSI interface, the encoder provides accurate absolute multiturn position information with stable sampling performance across the full operating speed range. High signal integrity and consistent timing characteristics support reliable real-time feedback, making the encoder suitable for motion control applications that require precise synchronization between the encoder and control system.
Mechanically, the encoder is designed to match common industrial mounting conventions, allowing installation without mechanical redesign. The robust construction supports operation under vibration, shock, and electrical interference typical of industrial machinery. Integrated self-diagnostic functions continuously monitor internal conditions, signal integrity, and operating limits, helping reduce unplanned downtime and improve overall system availability.


This replacement solution is ideal for automated production lines, servo-driven equipment, and industrial machinery that depend on accurate absolute position feedback and dependable long-term performance.
