The ASS58N-F3AAAR0GN-0016 is a singleturn absolute encoder designed for high-accuracy SSI feedback in advanced automation systems. We provide a 1:1 replacement alternative that mirrors the original mechanical structure, communication protocol, and performance. This encoder features a 58 mm enclosure, recessed hollow shaft, and precise 16-bit resolution, offering consistent positional feedback in real-time.
Its solid-state design ensures exceptional reliability, withstanding vibration, dust, and heat typical of industrial settings. The replacement is simple to install and requires no coupling or alignment modification. This model has proven reliability in automation lines, steel manufacturing, and chemical industry applications across Asia, Europe, and the Middle East.
