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.
Low-Cost Input Device (can replace multiple switches or potentiometers)
Less than 1" square fitting into even smaller enclosures
100,000 life cycles for reliability and long life
1/4" threaded shaft with flatted end for knob, mounts in enclosure or on PCB
