EC12 series Insulated shaft type encoder is an encoder with a wide range of applications. A 12mm sized unit achieved high resolution,12 pulse/12 detent and 24 pulse/24 detent. Used a new structure for the shaft and bushing, and achieved a high precision, responsive system.
This datasheet describes the ALPS EC12 Series rotary encoders, covering both incremental and absolute types. It lists the available shaft options, detent configurations, and mechanical dimensions for each model.
Key electrical characteristics such as operating voltage, current, and signal output are detailed, along with mechanical performance data like operating life, torque, and environmental limits. The document also includes mounting dimensions and switch specifications for variants with push‑on switches.
