The BOURNS PEC11R-4220F-S0024 is a mechanical rotary incremental encoder. This small-sized encoder has a flat design and weighs only 0.97oz.in. It provides straight quadrature digital square wave output with a resolution of 24 pulses per revolution (PPR). The encoder is designed to be mounted using through-hole PC pins for easy installation. It is suitable for applications that require precise rotary position sensing, such as in robotics, industrial control systems, and electronic devices.
