Bourns PEC11J Series 12mm Rotary Encoders are designed for professional audio and lighting applications and consumer electronics. These encoders feature a quadrature output, flatted shaft, various resolutions, and a momentary push switch option. Suitable for applications where a menu select encoder is required, these encoders have an IP40 dust seal rating and a long 100,000 rotation cycle life. Bourns PEC11J encoders are drop-in replacements for the discontinued ALPS Model EC11J and enable users to continue to support existing applications.
