Encoder module P11159-01AS Small package and high resolution encoder module The P11159-01AS 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 P11159-01AS produces a 2-phase digital signal output matching the slit movement.
