The NSE 5310 Rotary Encoder was discontinued by AMS OSRAM, but we maintain stock on this part to support programs who still require the component. We have stock on the NSE-5310-ASSU and can support your ongoing requirements. The TRACKER NSE-5310 is an incremental position sensor with on-chip encoding for direct digital output. A Hall element array on the chip is sued to derive the incremental position of an external magnetic strip placed above the IS at a distance of 0.3 mm. This sensor array detects the ends of the magnetic strip to provide a zero-reference point. The integration of Hall-effect position sensors, analog front end and digital signal processing of a single IC chip provide an ingeniously small position sensor, without the need for external pulse counters.
