Key benefits Accurate bidirectional counting: Tracks rotation pulses in both positive and negative directions so you can measure rotation amount and direction precisely. Continuous rotation for flexible control: Unlike a potentiometer, this encoder supports continuous rotation without end stops, allowing unrestricted rotational input and fast adjustments. Easy calibration and reset: On-board button(s) let you reset the counter to the original state quickly, simplifying setup and repeatable operations. Compact and system-friendly: Small footprint and 5V operating voltage make it easy to integrate into typical 5V control systems and hobby or industrial projects. What it does (function and performance) Counts output pulses generated during rotation and registers direction (positive/negative). Pulse rate: 20 pulses per revolution (20 PPR), providing consistent incremental feedback. Operating voltage: 5V. No inherent speed limit on rotation, enabling continuous and rapid turning compared with a potentiometer. Reset functionality via button(s) on the encoder to restore the counter to its original state. Key specifications and physical attributes Operating voltage: 5V (compatible with 5V logic and controllers). Pulse rate per revolution: 20. Size: 33 mm x 23 mm. Built-in button(s) provide an onboard reset function. Practical use scenarios User interface dial: Use as a precise input knob for menu navigation, volume or parameter tuning where counting increments and direction matter and a continuous dial is preferred over a potentiometer. Position or movement tracking: Integrate into small robotics or automation projects to count rotations, detect direction changes, and monitor incremental movement. Control systems and instrumentation: Feed encoder pulses into microcontrollers or counters for rotational monitoring, speed approximation, or step-based adjustments where resettable counts are required. Why choose this encoder Delivers clear incremental counts with direction awareness for accurate control and measurement. Compact 33 mm x 23 mm size and 5V compatibility make it straightforward to add to many projects. On-device reset button(s) and continuous rotation capability simplify operation and expand application flexibility.
