PEC11R-4215F-S0024
Overview
The Bourns PEC11R-4215F-S0024 is a 12mm incremental rotary encoder featuring a metal flatted shaft and an integrated momentary push switch. It provides 24 pulses per 360-degree rotation with 18 detents, making it suitable for tactile user interface navigation in compact electronic devices. The rugged metal bushing and shaft construction ensure high reliability for through-hole PCB mounting applications.
Why Choose This Part
This encoder features a compact 12mm form factor with a rugged metal shaft that offers superior mechanical durability compared to plastic alternatives. The integrated push switch allows for single-knob operation of both selection and navigation, saving PCB real estate and reducing bill-of-materials costs.
Applications
Getting Started
To interface this encoder, connect the A and B quadrature outputs to microcontroller GPIO pins with internal or external pull-up resistors (typically 10k ohms). Use a hardware or software debounce circuit with a time constant of approximately 2ms to filter switch and signal noise. For software, a state machine or interrupt-driven approach is recommended to accurately track clockwise and counter-clockwise rotations.
