Hey DIYers and electronics tinkerers, this 10-pack of Fielect EC16 rotary encoders is super handy! These are 360-degree continuous rotation encoders (not potentiometers with stops) that output digital pulses as you turn the shaft, perfect for adding control knobs to your projects. They have a full 20mm shaft, 5 pins for easy wiring, and a screw thread on the bushing for secure mounting. Rated for 5V DC, they're commonly used in things like volume controls, menu navigation on displays, robotics, or custom input devices. Each rotation has 20 detents or 'clicks' for precise feedback. They're a standard component, reliable, and having a 10-pack means you can experiment or have spares. A must-have for anyone building custom controllers, audio equipment, or Arduino/Raspberry Pi projects.
