This EC11 rotary encoder switch is made for surface-mount (SMD) circuit boards, offering a compact way to add user input. It's an incremental encoder that sends out digital pulses as you turn it. The built-in push-button switch simplifies panel design by combining two functions into one part. Features and Benefits
- 5-pin SMD type - It mounts directly onto the surface of a PCB, saving space and making assembly easier for modern electronics.
- Integrated push switch - It combines rotational input with a press-to-select function, good for user interfaces.
- Tactile detents - You get a distinct click for each rotational step, allowing for confident, eyes-free operation.
- 10mm handle length - This offers a practical shaft length that works well for panel mount controls where a knob will be attached. Applications
- Serving as an audio digital potentiometer for volume and tone controls on small gear.
- Implementing data entry and menu selection on an industrial HMI or custom control panel.
- Adding a multi-function control knob to DIY Arduino projects with limited panel space.
What It Is
A rotary encoder is an electromechanical device that converts angular position or motion into an analogue or digital signal. This specific product is a rotary encoder switch, meaning it combines the rotational sensing function with an integrated push switch. It features a 5-pin configuration and a 10mm plum shaft, designed for surface-mount device (SMD) applications. This incremental encoder provides feedback on rotation, allowing for precise control in various electronic projects and devices.
Key Uses & Applications
This rotary encoder with a push switch is ideal for applications requiring both rotational input and a momentary switch function. As a position sensor, it is commonly used in user interfaces for electronic equipment, such as adjusting volume on audio systems, navigating menus on display panels, or setting parameters in control systems. Its compact SMD type mounting makes it suitable for integration into printed circuit boards where space is a consideration. The low voltage specification ensures compatibility with typical electronic circuits.
How to Choose
When selecting a rotary encoder, consider the required functionality, such as the need for an integrated push switch, as featured in this product. Evaluate the mounting type; this is an SMD type, suitable for surface mounting. Pin configuration is also crucial, with this product offering a 5-pin setup for connectivity. The shaft type and length, in this case, a 10mm plum shaft, should match the intended knob or interface. Always ensure the voltage requirements align with your project's power supply, noting this product operates at low voltage.
Grit / Spec Guide
This product is a rotary encoder and does not have a grit specification. Its key specifications are:
- Function: Rotary Encoder with Push Switch
- Mounting Type: SMD Type
- Pin Configuration: 5 pin
- Quantity: 5 pieces
- Shaft Length: 10mm
- Shaft Type: Plum Shaft
- Voltage: Below 50Vac or 75Vdc (EU LVD compliant)
These details are critical for ensuring compatibility and correct integration into electronic circuits. The plum shaft design provides a secure fit for corresponding knobs.
Care & Safety
Rotary encoders, being electromechanical devices, require careful handling during installation and use. Ensure all connections to the 5 pins are correctly made to avoid damage to the encoder or the connected circuit. As this product is designed for low voltage applications (below 50Vac or 75Vdc), always operate it within these specified limits to prevent electrical hazards. Avoid applying excessive force to the 10mm plum shaft or the push switch, as this can lead to mechanical failure. Store in a dry environment to prevent corrosion of the pins.

A: This is an SMD (Surface Mount Device) type encoder. It's designed to be soldered directly onto the surface of a printed circuit board.. Q: What is the handle length and type? A: The handle, or shaft, has a length of 10mm. It's a plum shaft, which is a D-shaped profile for knobs that use a set screw or have a matching D-hole.. Q: Does this encoder also have a push button function? A: Yes, it does. In addition to rotating, the shaft can be pressed down to activate a separate momentary switch, giving you an extra input from the same component.. Q: How many encoders do I get in one order? A: Each order includes five of the SMD encoders. This is helpful for projects that need several control knobs, like a custom MIDI controller or audio device.. Q: What happens if a switch is bad after I've already soldered it? A: Our return policy covers parts in their original, unused condition. We recommend testing the switch and rotation contacts with a multimeter before soldering it to your board to confirm it's working correctly..
