Pressure fluids
The following rules apply for the operation with var-
ious pressure fluids: The above information serves
for orientation and does not substitute user tests
among the particular operating conditions. Partic-
ularly no liability for media compatibility may be
derived out of it.

Electrical connection
The electrical connection of the valve takes place
by one common cable, which is coupled to the in-
tegrated electronic driver by a central connector
assembly.
The connection Codes F0, G0, M0, S0 requires a
6 + PE female connector EN 175201-804.
HFA Oil-in-water emulsion
HFB Water-in-oil emulsion
HFC Aqueous solution (glycols)
HFD Unhydrous fluids (Phosphor-Ester)
The female connector has to be ordered sep-
arately under article nr. 5004072.
A female connector with metal housing is re-
quired! Plastic made models may create func-
tion problems due to insufficient EMC-char-
acteristics.
The connecting cable has to comply to the follow-
ing specification:
Cable type control cable, flexible, 7 conduc-
tors, overall braid shield
Cross section min. AWG16/1.0 mm
2
Outer dimension 8...12 mm
Cable length max. 50 m
For cable lengths > 50 m consult Parker.
The connection cable is coupled to the female con-
nector by solder joints.
Skinning lengths for the connecting cable:
Do not disconnect cable socket under ten-
sion!
