Rotary Encoder | 5-Pin with Push Button | 15mm/20mm Half-Moon Shaft

This EC11 rotary encoder gives you precise digital input for your electronics projects. It combines 360-degree rotation with a push-button in one part. Unlike a potentiometer that outputs a changing analog voltage, this incremental encoder sends digital pulses. This works well for menu navigation or setting adjustments. Features and Benefits - 20 detents per rotation - Each click gives you tactile feedback. You can make exact adjustments without looking. - Integrated push-button switch - This adds a second function, like 'select' or 'mute'. It saves space and wiring. - Multiple shaft options - It comes in 15mm or 20mm lengths. Half or plum blossom shaft types fit different knobs and enclosures. - Standard 5-pin layout - The EC11 rotary encoder connects directly to microcontrollers. This makes it easy to use in Arduino projects. Applications - Audio equipment - Use it as a digital volume control knob or menu selector in DIY amplifiers and synthesizers. - User interfaces - It's a good choice for navigating menus, changing settings on an LCD, or controlling parameters in custom devices. - Motor control - It provides fine-tuned speed or position control for stepper and servo motors in robotics and automation. What It Is A rotary encoder is a type of position sensor. This specific model is a 5-pin rotary encoder with a push button, featuring a 15mm or 20mm half-moon shaft. It functions as a digital potentiom with a switch. An encoder converts mechanical rotation into a digital signal, making it a digital sensor. This device is an incremental encoder, providing feedback on rotational movement. It is designed for applications requiring precise control and input. Key Uses & Applications This rotary encoder is primarily used as a controller in various electronic projects and devices. Its digital potentiom with switch function makes it suitable for applications needing both rotational input and a distinct push-button action. Given its voltage rating of below 50Vac or 75Vdc, it integrates well into low-voltage circuits. Common uses include volume control, menu navigation, and parameter adjustment in audio equipment, control panels, and embedded systems. How to Choose When selecting a rotary encoder, consider the shaft type and length required for your application. This product offers a half / plum blossom shaft in 15mm or 20mm lengths. Verify the pin configuration matches your circuit design; this model uses a 5-pin layout. Ensure the voltage rating of below 50Vac or 75Vdc is compatible with your system. The inclusion of a push button provides an additional function for control. Grit / Spec Guide This product is a rotary encoder, not a abrasive or cutting tool, so grit specifications are not applicable. The key specifications for this model (EC11) include its 5-pin configuration and half / plum blossom shaft type. Handle length options are 15mm and 20mm. It functions as a digital potentiom with a switch. Its voltage rating is below 50Vac or 75Vdc. These details are crucial for integration into electronic projects. Care & Safety When handling this rotary encoder, ensure power is disconnected if making or breaking connections. The voltage rating is below 50Vac or 75Vdc, so it is designed for low-voltage applications. Avoid applying excessive force to the shaft or push button to prevent mechanical damage. Protect the encoder from dust and moisture, which can affect its operational lifespan. Store in a dry, clean environment to maintain functionality.
