40 m.
Connection Diagrams for 12V Encoder Systems
For encoder supply, use lines with the same line cross section.
ES with "MSK/QSK Encoder Inter‐
face" for Encoder Systems S1/M1,
S2/M2, S5/M5
1) Cable cross section ≥ 0.5 mm²; observe allowed encoder cable length
2) Cable cross section ≥ 0.14 mm²

tems S1/M1, S2/M2, S5/M5
For direct connection to the encoder system use our cable
RKG4200. For connector type and encoder connector pin assign‐
ment, please see the cable documentation.
Connection Diagrams for 12V Third-Party Encoder Systems
For encoder supply, use lines with the same line cross section.
Observe that the third-party encoder used has to be suited for the
voltage available at the encoder evaluation ES as voltage for en‐
coder supply.
