Encoder module P11159-201AS Small package and high resolution encoder module The P11159-201AS is an optical encoder module that consists of a photo IC and red LED. The photo IC incorporates a 4-element photodiode and a 2-phase digital signal output circuit. When using 0.2 mm pitch slits, the P11159-201AS produces a 2-phase digital signal output matching the slit movement. Features Applications High resolution: 0.05 mm (2-phase output) Rotary encoder Positioning pin for easy alignment Linear encoder Small package Suitable for lead-free flow soldering Absolute maximum ratings (Ta=25 °C) Parameter Forward current*1 Input Reverse voltage (LED) Power dissipation Supply voltage Output voltage Output (photo IC) Output current Power dissipation*2 Operating temperature Storage temperature Soldering Symbol IF max.
