This EC12 rotary encoder gives you precise digital input with clear, tactile feedback. Each 360-degree turn has 24 distinct positions, or detents. These match 24 output pulses. The built-in push-button switch adds a second function, like select or enter, in one part. Features and Benefits
- 24 Pulses & Detents - Gives stepped, accurate adjustments. This makes scrolling through menus or fine-tuning settings easy.
- Built-in Push Button - You can press the shaft. This combines rotational control and a momentary switch. It saves panel space.
- 18mm Half Shaft - The D-shaped shaft fits standard control knobs securely. This stops slippage during use.
- 5-Pin Configuration - Uses a common pinout (GND, +V, SW, DT, CLK). It's simple to wire for DIY electronics and audio gear. Applications
- Audio Equipment - Adjusts volume, panning, or effects parameters on a mixing console or synthesizer.
- DIY Electronics - Navigates menus and changes values on a display for microcontroller-based projects.
- Custom Interfaces - Acts as a main user control for setting timers, brightness, or modes on custom-built devices.
What It Is
A rotary encoder is a type of position sensor. This particular model is an Encoder with Push Button, designed with an 18mm Half Shaft. It functions as a mechanical transducer, converting rotational movement into digital signals. This incremental encoder has 5 pins and offers 24 pulses per revolution with a 360-degree rotation angle. The integrated button switch provides an additional control function.
Key Uses & Applications
This rotary encoder is primarily used as a controller in various electronic systems. Its 24-pulse output makes it suitable for applications requiring precise positional feedback. The integrated push button allows for selection or activation alongside rotational input. A common application is within audio mixers, where the 24-pulse resolution and push-button functionality are beneficial for controlling parameters like volume, pan, or menu navigation.
How to Choose
When selecting a rotary encoder, consider the required shaft type and length; this model has an 18mm Half Shaft. The number of pulses per revolution is critical for desired resolution; this encoder provides 24 pulses. The presence of an integrated feature, such as a button switch, can simplify designs. Ensure the number of pins, in this case 5-pin, is compatible with your circuit.
Grit / Spec Guide
This rotary encoder features 24 pulses per revolution, meaning it provides 24 distinct steps for every full rotation. It has a 360-degree rotation angle, allowing for continuous input. The shaft length is 18 mm, and it is a Half Shaft type. The material used is ABS. The integrated button switch provides an additional input method alongside the rotational sensor.
Care & Safety
Ensure proper handling to avoid damage to the 5-pin configuration and the 18mm Half Shaft. When installing, align the shaft correctly to prevent bending. Avoid excessive force when pressing the integrated button switch. Protect the ABS material from harsh chemicals or extreme temperatures to maintain its integrity. Disconnect power before installation or removal to prevent electrical hazards.

A: This encoder has 24 distinct positions, or detents, that you can feel as you turn the knob. It also outputs 24 digital pulses for each full 360-degree rotation.. Q: What's the expected lifespan of these encoders? A: They are built for frequent use. The rotational part is rated for at least 30,000 cycles, and the integrated push-button switch is rated for 20,000 presses.. Q: Could I use this rotary encoder for a volume knob on a custom audio device? A: Yes, that's a very popular application for this kind of rotary encoder. The 24 steps give you good control resolution, and the built-in button is useful for functions like mute or input select.. Q: What are the dimensions of the shaft? A: The shaft has a total length of 18mm and a diameter of 6mm. It's a D-type or 'half-moon' shaft, so it will fit knobs designed for that shape.. Q: The title says '2PCS'. Does this mean I get two encoders? A: That is correct. The price includes a pack of two identical EC12 encoders. Both will have the 24-pulse output, the push-button switch, and the 18mm D-shaft..
