The OKY3477 is a three-terminal, analog, position sensing potentiometer produced by OKYSTAR. It is designed to work with a single supply voltage of between 3.3 and 5VDC, making it suitable for many different microcontroller applications. It has a linear Output voltage which increases or decreases in proportion to the angle of the shaft. The resistance range is between 10KO, 20KO, 50KO, 100K, 500KO and 1MO. It is packaged in an 8-pin DIP and has a rotational life of 10,000 cycles.
