CPX−AB−4−M12x2−5POL (−R), CPX−M−4−M12x2−5POL
Recommendation for the 4−input module:
Use the Festo DUO cable in order to connect two sensors to
sockets X1 and X3 with one plug at low cost.
CPX−AB−4−M12x2−5POL −R ,
CPX−M−4−M12x2−5POL
The metal thread of these sub−bases is connected internally
with pin5 (functional earth FE).
