Bourns Mechanical Rotary Encoder 20 PPR Incremental, 6 mm Metal Flatted Shaft, PCB Mount PEC11H-4120F-S0020

The Bourns PEC11H-4120F-S0020 is a precision mechanical rotary encoder designed to provide incremental position feedback with 20 pulses per revolution. Engineered for electronic and industrial control panels, this encoder features a durable 6 mm metal flatted shaft, making it well-suited for demanding operational environments.

As an incremental encoder, it outputs digital square waves proportional to the angular movement of the shaft. The surface mount PCB style allows direct soldering onto circuit boards for integration into various assemblies, including level controls, timers, and tuning interfaces.

The shaft length of 20 mm ensures compatibility with panels and enclosures of different depths, while the non-indexed design supports smooth, continuous rotation - ideal when precise but unrestricted positioning is needed. The metal shaft construction increases mechanical robustness, providing high rotational life and reliability even with frequent use.

With a rated output current of 10 mA, this rotary encoder is optimized for low-power signal and control circuits. The RoHS compliance affirms its suitability for environmentally conscious manufacturing and integration across global markets.

Applications for this encoder include industrial automation, electronic instrumentation, audio equipment, medical devices, and any system where real-time angular position sensing is required. It is widely used for volume adjustment, parameter setting, and menu navigation in embedded systems and programmable controllers.

Bourns encoders are trusted for their accuracy and dependability in both commercial and industrial environments. Discover more Rotary Encoders and advanced sensing solutions in the Electronics & Electricals category, under the Bourns brand on EnvMart.
