SA48 (TS5667N480)

SA48 Smart Absolute Encoder is an ultra-small,multi-turn type absolute encoder with a hollow shaft. It is shaped for easy installation on small AC servo motors.

The resolution for output is 11 bits for a single turn or 13 bits for multiple turn. The number of signal lines is minimized by the use of a serial data transmission mode. The encoder outputs incremental signals (2048C/T A,Bch, 1C/T Zch) in addition to absolute signals

Features

• Ultra-small size
• Serial data transmission mode
• Self-diagnostic function
• At power outage, multiple revolution data are backed up by an externally installed battery and built-in capacitor.
