The ASS58N-F1AK1A0GN-0012 is a singleturn absolute encoder widely used in industrial automation systems where accuracy and signal reliability are critical. We offer a 1:1 replacement solution for this model, fully compatible in both mechanical and electrical specifications. The replacement encoder supports SSI communication and features a 58 mm compact housing, recessed hollow shaft, and high-speed RS422 interface for efficient data transfer.
With a 16-bit resolution design, it provides precise position detection with smooth signal response, ideal for robotics, packaging, and factory control environments. The microcontroller-based internal logic ensures consistent synchronization between the encoder and the control unit. Designed for direct shaft mounting without couplings, this encoder delivers easy installation and long-term stability even under heavy vibration.
