Incremental Rotary Encoder

This Incremental Rotary Encoder provides 16 pulses per revolution via 2-bit quadrature outputs. 3-pin SIP header provides easy breadboard connection. This encoder rotates continuously through 360 degrees and provides detent to hold position. Used with a push button this encoder could provide a complete menu / input system for your microcontroller.
