Note
HEIDENHAIN recommends:
Preferably use a conductor cross section of 0.34 mm
2
if you use stranded
wires with wire-end sleeves. This cross section can be clamped
appropriately and ensures a reliable terminal connection.
If you use stranded wires with wire-end sleeves and a conductor cross
section of 0.5 mm
2
, the Weidmüller PZ 6/5 crimping pliers (setting 0.25–
0.5 mm
2
) must be used for crimping. In this case, orient the crimped wire-
end sleeve before inserting it into the socket connector. If crimping pliers
from other manufacturers are used for crimping conductors with a cross
section of 0.5 mm
2
, the crimped wire-end sleeves cannot be inserted into
the socket connector and clamped appropriately, and therefore do not
result in a reliable terminal connection.
