Electrical Plugs
and Connectors
DIN 43650 Connector
Cable diameter range:
Wire section range:
Terminals:
Type of protection:
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 ) is opened,
1
the energy stored in the coil
is trapped and dissipated by
the diode (D ).

• Works only with DC voltage
• Polarity dependent
• Increase drop out time

Screw type
IEC144 class IP65, when
plugs are fitted correctly to
the valves with interface
seals (supplied with plugs)

Transzorb
Diode and Zener diode in par-
allel with coil. When switch
(S ) is opened, the energy
1
stored in the coil is trapped
and dissipated by the diode
(D ) and Zener diode (Z ) and
1 1
the coil resistance.
• The Zener makes exact limi-
tation of inductive spikes.
• Works only with DC voltage
• Polarity dependent
