Electrical Plugs
and Connectors
Cable diameter range: Ø6–10 mm (0.24–0.40)
Wire section range: Ø,5–1,5 mm2 (0.0008–
0.0023 in2)
Terminals: Screw type
Type of protection: IEC144 class IP65, when
plugs are fitted correctly to
the valves with interface
seals (supplied with plugs)
in place.
DIN 43650 Connector
Connector can be positioned
at 90° intervals on valve by
re-assembling contact holder
into appropriate position
inside connector housing.
Use U12 or U11 type connec-
tors with 12 and 24V DC coils
if rectification is required.
Connectors with and without
indicator lights are available
(order separately):

Surge Suppression Devices
(For DC Valves)
Standard diode
Diode in parallel with coil.
When switch (S
1
) is opened,
the energy stored in the coil
is trapped and dissipated by
the diode (D
1
).
• Works only with DC voltage
• Polarity dependent
• Increase drop out time
Transzorb
Diode and Zener diode in par-
allel with coil. When switch
(S
1
) is opened, the energy
stored in the coil is trapped
and dissipated by the diode
(D
1
) and Zener diode (Z
1
) and
the coil resistance.
• The Zener makes exact limi -
tation of inductive spikes.
• Works only with DC voltage
• Polarity dependent
NOTE: These surge suppres -
sion devices are “Polarity
Dependent.” Proper biasing
conditions must be met
when installing/connecting
a coil in a system.

Times represent cessation/
application of voltage to coil
versus velocity (start/stop)
of a cylinder using a single
solenoid, spring offset valve
(time in milliseconds).
