This Bourns incremental rotary encoder outputs quadrature signals with push-switch functionality, designed for audio and industrial parameter control applications.

The PEC11R-4220F-S0024 is an incremental mechanical rotary encoder that delivers quadrature A/B-phase digital output with 24 detents and pulses per revolution. This device converts rotary mechanical movement into electrical signals to detect rotation direction, position, and speed.

• Integrated momentary push-button switch for function confirmation
• Compact 11-mm size with through-hole PCB mounting
• Operating temperature range: -30°C to 70°C
• Long mechanical lifespan with stable anti-interference performance

Primarily used for human-machine interaction and parameter adjustment in various industrial and commercial applications:

• Professional audio equipment
• Consumer electronics
• Industrial control panels
• Automotive control modules
• Precision instruments

Provides reliable rotary input control for volume tuning, mode switching, parameter setting, and functional selection.
