For the GM400.020A102 and GM400.A20A102 encoder variants, we offer a fully compatible SSI encoder 1:1 replacement engineered for high-demand industrial environments. The replacement solution maintains identical interface characteristics and functional logic, ensuring a seamless transition during maintenance or retrofit projects.
Using an SSI interface, the encoder provides precise absolute multiturn position information with reliable data transmission across a wide range of operating speeds. The design supports stable sampling behavior and consistent signal timing, making it suitable for motion control systems that require accurate real-time feedback. Compatibility with standard code configurations ensures smooth communication with existing control platforms.
Mechanically, the encoder aligns with established flange and shaft standards, allowing installation without mechanical redesign. The robust construction is optimized for industrial use, offering resistance to vibration, shock, and electrical interference. Integrated self-diagnostic functions continuously monitor internal processes, signal limits, and operating conditions, supporting predictive maintenance strategies and enhancing overall system availability.
This replacement encoder is an ideal choice for automation systems, drive-controlled machinery, and industrial positioning applications where precision, reliability, and long service life are critical.
