Overview

The PEC12R-4220F-S0024 is a 12mm incremental rotary encoder featuring 24 pulses per revolution and a built-in momentary push switch. It provides a standard 2-bit quadrature output and is designed for horizontal PCB mounting via through-hole pins. This component is ideal for user interface navigation where both rotational input and tactile selection are required.

Why Choose This Part

This encoder features a compact 12mm form factor with a flatted 6mm shaft, making it easy to pair with standard control knobs. It includes a physical detent for tactile feedback during rotation and is rated for a minimum rotational life of 30,000 cycles.

Applications

Audio Equipment Volume Control
Providing digital volume adjustment and power/mute toggling via the integrated push switch.
Menu Navigation
Scrolling through options on OLED or LCD character displays in embedded systems.
Instrument Parameter Adjustment
Fine-tuning values like frequency, temperature setpoints, or timer intervals in laboratory or industrial gear.

Getting Started

Connect the quadrature A and B channels to microcontroller GPIOs with internal or external pull-up resistors to 5V or 3.3V. Implement a software debounce routine or hardware RC filter to handle contact chatter, and use interrupt-on-change pins to track rotation state transitions.
