EC11 Rotary Encoder With Push Button Switch 5pin 15mm
A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to digital output signals.
The EC11 Rotary Encoder With Push Button Switch 5‑pin 15 mm is an incremental rotary input device combining a 20‑step detented encoder and a momentary push‑button switch. Encased in durable metal shaft construction and designed for through‑hole PCB mounting, it is ideal for mechanical user interfaces in embedded systems and audio controls.
Features
- Continuous rotary encoder switch with built-in push button
- Can be used for data entry as with modern in-car CD players, for volume & on/off control or data selection via LCD
- Simple to use with PIC or ATMEL microcontrollers (Arduino-like MCUs).
- Knurled metal shaft of 15 mm length and approximately 6 mm diameter for secure grip.
- 20 detents per revolution (step angle ≈18°) delivering tactile feedback.
