Description

The EC11B5AI is a mechanical incremental rotary encoder that translates shaft rotation into digital quadrature pulses. Its contact-based readout provides a tactile detent feel and precise positional feedback, making it ideal for user interface controls like volume knobs, menu selectors, and parameter adjustments.

Built with a compact footprint and a standard 19.5mm shaft height, it is engineered for direct PCB mounting in space-constrained electronic assemblies. The encoder is compatible with common 3.3V and 5V logic systems, facilitating straightforward integration with development platforms like Arduino, Raspberry Pi, and industrial PLCs for motion and position sensing tasks.

Key Features

  • Incremental Encoding: Generates A/B quadrature output signals for precise direction and speed detection.
  • Tactile Detent: Provides distinct mechanical feedback for each step, enhancing user interface control.

Frequently Asked Questions

What is the output signal type of the EC11B5AI encoder?

The EC11B5AI is an incremental encoder that outputs a standard quadrature signal. This consists of two channels (A and B) phased 90 degrees apart, allowing a connected microcontroller to determine both the direction of rotation and the relative position based on the pulse sequence.

What is the typical operating voltage for this rotary encoder?

This encoder is designed for use with standard digital logic levels. It is typically operated at 3.3V or 5V DC. Always connect the common pin to ground and use pull-up resistors on the A and B output lines as required by your microcontroller's input circuitry for reliable signal reading.

How do I mount and interface the EC11B5AI encoder?

The encoder is designed for surface-mount (SMD) or through-hole PCB installation with a 19.5mm shaft height extending above the board. It features a standard 3-pin configuration (A, B, Common). You must attach a knob to the splined 'plum blossom' shaft. The quadrature outputs connect directly to digital I/O pins on an Arduino, Raspberry Pi, or other microcontroller for decoding.
