The ASS58N-F3AK1A0BN-0013 is a high-precision singleturn absolute encoder developed for modern automation and motion control systems. Our OEM replacement unit replicates the original encoder’s SSI communication protocol and mechanical interface while enhancing long-term supply stability. With a 58 mm housing, 16-bit resolution, and recessed hollow shaft, this encoder ensures smooth, accurate positional data transfer at speeds up to 2 MBaud.
Constructed for durability, it features optical isolation on signal lines and a robust body for harsh industrial conditions. Installation is simplified through direct shaft mounting, eliminating the need for couplers or adapters. This model is successfully applied in global industries, including steel manufacturing, robotics, and chemical automation lines.
