.. E38S6G5-600B-G24N .. aber dieser macht gar nichts .. 0.06V kann ich zu VCC messen und 0.16V zu GND ..
Du hast ne Versorgung dran? Nach nem (ersten) Klick im www gabs diese Liste:

DC5V-24V 600P/R Encoder Incremental Rotary 360 Pulses/R AB 2 Phase 6mm Shaft Features :

    Part Number: E38S6G5-600B-G24N
    600 p/r 
    Power source: DC5-24V
    Shaft: 6*13mm
    Size: 38*35.5mm
    Output : AB 2phase output rectangular orthogonal pulse circuit, the output for the NPN open-collector output type
    Maximum mechanical speed: 5000 R / min
    Response frequency: 0-20KHz
    Cable length: 1.5 meter
    Notice: AB 2phase output must not be directly connected with VCC, otherwise, will burn the output triode,  because different batches, and may not have the terminal
