Check the listing for details. 360 Degree Rotary Encoder Code Switch EC11 5 Pins 20mm for Industry,5Pcs. Condition: New. Listed at 15.35 USD. Encoder Code SwitchWhy Choose This:★Type: Encoder code with Switch; Adjustment method: 360 Degree; Number of pulses: 20; Pin Numbers: 7(5 working signal pins & 2 mounting pins); Rated Voltage: 5 Volt.★By rotating the rotary encoder can be counted in the positive direction and the reverse direction during rotation of the output pulse frequency, unlike rotary potentiometer count, this rotation counts are not limited. With the buttons on the rotary encoder can be reset to its initial state, that starts counting from 0.★In the forward rotation, the A line phase leads the B line phase; when reversed, the B line phase leads the A line phase. The phase relationship and number of rotations of AB can be identified using a simple digital logic circuit (exclusive OR gate and D flip-flop).★Shaft Diameter: 6mm/0.24"; Shaft Height: 20mm/0.
