1 Description
The slip-on coils can be replaced without opening the hy
draulic envelope and can be positioned at any angle
through 360°. When combined with the appropriate core
tube, the coils produce an on/off solenoid function or a pro
portional solenoid function. Thanks to the wide variety of
connector types and voltages, these coils are suitable for
widespread use in mobile and industrial applications. These
coils are very adaptable in use, a benefit that is enhanced
by various power ratings and an optional protection diode.
The coil encapsulation and the plug base are glass-fibre re
inforced thermoplastic.

ATTENTION!
Protection of AC solenoid coils.
The rectifier built into the coil can be damaged by
high voltage spikes.
To prevent AC coils from being destroyed, a mat
ing connector with integral power varistor is re
commended.
IMPORTANT!
For solenoid coils with integrated rectifier as well
as for solenoid coils without protection diode and
for solenoid coils with bipolar protection diode the
two supply connections (UN) can be inter
changed. The earth connection is marked with …
ATTENTION!
Coils with a bipolar protection diode:
To protect the diode in the coil against overvoltage
and overcurrent the related data for this diodes
must be observed!

5 Installation information
Attention.
Because of the danger of overheating, the coil
must only be operated when it is properly fitted on
a valve. To prevent the ingress of water, both ends
of the coil on the core tube must be properly
sealed with O-rings.
Attention.
Delivery is done without mating connector.
