This Bourns incremental rotary encoder converts rotation to digital signals for audio and industrial parameter control.

PEC12R-4220F-S0024 is a 12-mm incremental mechanical rotary encoder manufactured by Bourns. Key features include:

• 2-bit quadrature digital square-wave output with 24 pulses per revolution (24 detents)
• Built-in momentary push switch
• IP40 dustproof grade
• Compact through-hole PCB mounting structure
• 6-mm flat shaft with 20-mm shaft length
• Converts rotary mechanical motion into electrical digital signals
• Detects rotation direction, angle, and speed
• Maximum 100 rpm operation speed
• 30,000-cycle mechanical service life
• Stable performance under -30℃ to 70℃ working temperature

This encoder is widely used for parameter adjustment and man-machine interaction in various applications:

• Audio-visual equipment volume/tuning control
• Timer setting
• Consumer electronic device mode switching
• Industrial panel knob control
• Medical device parameter regulation
• Automotive interior control modules
• Small-size precision control equipment requiring compact structure and high-reliability rotary input
