Technical data
The coils are specially designed to operate in the
aggressive environment of high humidity and
temperature fluctuations that you find in most
refrigeration systems.
The new Clip-on fastening system ensures a
faultless installation and makes the coils easy
to mount and dismount. A Danfoss Clip-on coil
can be mounted without any tools at all, and
it is simple to dismount the coil by means of a
screwdriver.
The Clip-on coils are available for the
entire range of Danfoss solenoid valves for
refrigeration, freezing and air conditioning
purposes.
Introduction
3-core cable
The external thread in the screwed cable entry
suits flexible steel hose or corresponding cable
protection.
Terminal box
Leads are connected to terminal screws in the
terminal box. The box is fitted with a Pg 13.5
screwed entry for 6 → 14 mm cable.
Max. lead cross section: 2.5 mm
2
.
Connection
DIN plugs
The three pins on the coil can be fitted with spade
tabs, 6.3 mm wide (to DIN 46247).
The two current carrying pins can also be fitted
with spade tabs, 4.8 mm wide.
Max. lead cross section: 1.5 mm

.
Use of the protective cap supplied will prevent
inadvertent contact with live parts.
DIN socket
(to DIN 43650)
Leads are connected in the socket. The socket is
fitted with a Pg 11 screwed entry for
6 → 12 mm.
